General description The MICRO III is a very small and handy single gas monitor for measuring toxic gases or oxygen deficiency resp. surplus. There are 7 models of the MICRO III available: MICRO III Display Keypad Memory model Gases and lines G 01 No No No O CO H S (*1) G 0 Yes No No O CO H HCN HCl SO 3 (*1) G 0s Yes No No O CO H THT (*1) 4 4 3 G 1 Yes No No NO Cl O 3 ClO G 03 Yes Yes Yes O CO H HCN HCl SO 3 (*1) G 03s Yes Yes Yes O CO H COCl THT (*1) 4 4 3 G 13 Yes Yes Yes NO Cl O 3 CLO (*1) Please take notice of the detection range of CO and H-sensors (see section alarm thresholds - ) The s(special-) variants distinguish itself by the possibility to measure special detection ranges, resp. special gases, which need a very specific measurement of the sensor signal. With the exception of the model G 01, all detectors allow connecting any sensor from the relevant line of the above table. Please also see section alarm thresholds standard settings and test gas chart Detection principle For measuring toxic gases and oxygen, the MICRO III uses electrochemical (EC) sensors. Electrochemical sensor (EC) The electrochemical cells contain an electrolyte, a working electrode (anode), a counter electrode (cathode) and, depending on the sensor type, a reference electrode. The cell is adapted to the gas to be monitored by specific electrodes and a suitable electrolyte. The electrochemical reaction generates an electrical signal, which is proportional to the gas concentration. GfG sensor cells are using the capillary diffusion barrier technology, which, in combination with additional temperature compensation, avoids effects caused by changing atmospherical pressure and temperature. 4

Turning on Turn the MICRO III on before you enter a possibly confined area. Only this makes sure that accidents caused by gas hazards are prevented. For turning on put the battery in or, if it is already fit, press button. Turn on (initial) Insert battery Turn on Press button At first stage the MICRO III checks, if a valid sensor is fit, and if not, the rear LED flashes. The display reads SENS.ERR. This fault report is indicated until a valid sensor is plugged in. Then the MICRO III does a complete self-check. Both LEDs light up shortly, and the buzzer sounds for approximately 1 second. The battery capacity is displayed as well (see check of battery capacity). The warm-up time of the sensor is indicated by an audible signal every second, and the display reads a countdown (only for the initial activation). Once the self-check is completed, the MICRO III turns to detection mode. The LCD display indicates the gas and the concentration, e.g.: Display 0.0 PPM alternating 0.0 CL Depending on the parameter setting, either a visual or an audible confidence beep in regular intervals is activated during the detection mode. This signal proves that the detector is ready for operation. You can choose between a visual and an audible signal (see confidence beep). 6
Display illumination Press button shortly to illuminate the display for approximately 8 seconds. Peak and minimum value memory The MICRO III provides a peak value memory (TOX sensors) or a minimum value memory (OX sensor). Press the DATA button for approximately seconds, and the display indicates the minimum value measured by the oxygen sensor respectively the peak value measured by the TOX sensor. If you do not hit any button within approximately 5 seconds, the detector returns to normal indication. If you press and hold the RESET button, the memory value is set to the current measurement value, and the detector returns to normal indication after 5 seconds. Turning the detector off or removing the battery deletes the memory as well. Turning off The current consumption of the MICRO III is very low. A single AA battery is sufficient for continuous operation of 6 months, depending on alarm and display conditions. Turn off Press buttons and simultaneously for at least 1 second 7
Alarm Should the gas concentration exceed a pre-set threshold, a visual and audible alarm is triggered immediately. The MICRO III provides 3 alarm thresholds: Detectors for: Description Alarm thresholds Toxic gases Oxygen AL 1 Alarm 1, exceeding s AL Alarm, exceeding s AL 3 Alarm 3, exceeding s AL 1 Alarm 1, falling below t AL Alarm, falling below t AL 3 Alarm 3, falling below s The thresholds AL1, AL, and AL 3 stand for instantaneous concentration alarms. Alarm signals The alarms are distinguished by means of different flash and sound frequencies of the visual and audible alarm signals: Audible and visual Alarm Alarm signal Priority alarm AL 1 Slow sound and Low x x... flash frequency Medium sound and AL 4 x 4 x... Medium flash frequency Fast sound and AL 3 8 x 8 x... High flash frequency The LCD display indicates the gas and the alarm threshold, e.g. Display 7.5 AL alternating 7.5 CL 8
Special notes for oxygen monitoring Sour gases like CO and SO are easily absorbed by the electrolyte of the oxygen sensor. This results in an increased oxygen signal of e.g. approximately 0.3 % of the measurement value per 1 Vol.-% CO. The oxygen sensor, therefore, cannot be recommended for continuous measurement in concentrations above 5 Vol.-% CO. If the carrier gas is a gas with a molecular weight, which is different from that for nitrogen, the display values may also be incorrect. There are no cross sensitivities of the oxygen sensor for toxic gas concentrations within the TLV range. Battery The MICRO III is powered by one 1.5 V AA battery (mignon). This battery allows a continuous operation of up to 6 months. The operational time may be reduced by frequent alarms, by display indication or by activated confidence beep. The correct battery type is: Duracell MN 1500 LR6 Battery alarm The MICRO III monitors the battery voltage permanently and gives a warning, if it falls below the minimum voltage, which is equivalent to approximately 5 % of the battery capacity. A battery alarm is indicated by an audible warning. Audible battery alarm Alarm signal Fast sound frequency ( strokes) x 6 seconds pause x.... The LCD display indicates the battery capacity XX bat, e.g. Display 5 bat 9
The remaining capacity after the first battery alarm allows detection for at least another 15 minutes. For safe operation, the battery is to be replaced as soon as possible. Should the battery voltage become so low that proper functioning is no longer possible, the detector turns off automatically. The display reads bat. EMPTY. This reading is shown until the battery is replaced or until the battery is discharged completely. Battery replacement (only in safe area, resp. outside of Ex-areas) Note: The Duracell MN 1500, LR 6 battery must be inserted or replaced in safe areas only. Take care of the correct polarity when fitting the battery (fit the plus pole first). Once the battery is fit, the MICRO III effects a self-check, testing the visual and audible alarms. Slide battery cover to the top Replace battery For battery replacement slide the battery cover to the top. Then take the old battery out and replace it by a new one. Note: Use only Ex-proof batteries in hazardous areas! Watch out for the correct polarity of the new battery! Fit battery with + pole first! 10
Check of battery capacity Activation of battery check Press button shortly Once the self-check is completed, the battery capacity is indicated by a multiple signal: 1 3 4 5 Number of signals empty full Battery capacity The capacity is also shown in the display: e.g. 90 bat = 90 % battery capacity. Display 90 bat Service mode In the service mode you can check the confidence beep and the calibration (sensor adjustment). Adjustment procedures are done by means of the keypad. Activation Activation of service menu Press button for approximaletly 5 seconds Display SERVICE 11
Once you activated the service menu, you can select the individual menu points one after the other by shortly pressing button. These menu points are: Confidence beep Sensor adjustment with fresh air Sensor adjustment with test gas The individual menu points are characterized by a certain display readout as shown below: Button Menu point Display Oxygen sensor TOX sensor Confidence beep Sensor adjustment with fresh air Sensor adjustment with test gas beep ON or beep OFF AUTO - CAL AUTO - ZPT beep ON or beep OFF AUTO - ZPT AUTO - CAL Press the RESET button changing its setting. to leave every menu point without For the procedures below you must have selected the relevant menu point: 1
Confidence beep In the standard setting the alternating display of gas and unit indicates that the detector is operated in detection mode. An additional confidence beep can be activated, reminding the user in regular intervals that the detector is working. The confidence beep interval is 1 minute. The audible signal can also be turned off again.

Sensor adjustment with fresh air The fresh air adjustment sets the MICRO III in clean ambient air to its nominal value, which is 0 ppm for toxic gases (e.g. CO, HS) and 0.9 Vol.-% for oxygen. This means, that for toxic gas sensors the zero point is adjusted, while for oxygen the sensitivity is calibrated.

The display reads the current measurement value and the kind of 14
gas and, alternating, CAL or ZPT. Successful adjustment is indicated by three buzzer signals and by STORE in the display. Should the detector notice a fault during the adjustment, the LED flashes in a high frequency, and the display reads ERROR. Potential faults are a faulty sensor or a gas concentration, which is beyond the valid tolerance. In such cases please call GfG service. Press the RESET button to acknowledge the fault indication. Once the adjustment is completed successfully, the MICRO III returns to detection mode. Sensor adjustment with test gas The test gas adjustment sets the MICRO III to a gas specific nominal value. This means that for toxic gas sensors the sensitivity is calibrated, while for the oxygen sensor the zero point is adjusted. For toxic gas sensors make sure that the fresh air adjustment is effected is effected before calibration. Now you need the correct test gas. Test gases are: For toxic gases, e.g. carbon monoxide (CO), hydrogen sulfide (HS), etc. For the correct test gas please refer to the test report of your detector. For oxygen 100 Vol.-% nitrogen (N). Calibration procedure: Put the calibration adapter over the diffusion inlet of the MICRO III. For avoiding mistakes in calibration make sure that the MICRO III is exposed to a constant test gas flow for approximaletly 3 minutes. The flow rate should be 0.5...0.6 l/min. 15

Sensor replacement Note: Sensors may only be replaced in safe areas. Before an expert replaces the sensor, the battery must be removed as described above. Slide the battery cover off the casing completely. Now pull the sensor out and replace it by a new one. With the exception of the model G 01 all detectors allow connecting any sensor from the relevant line. Finally re-fit battery and battery cover. Note: ERROR An error message may appear in the display, if the O-ring (sensor seal) is missing. In this case you have to replace the rubber ring. Adjustment by means of configuration program The optional configuration program allows to connect the MICRO III to a PC by means of an adapter and to change the settings below: Alarm thresholds Alarm activation and deactivation Deactivation of sensor adjustment in air or with test gas Calibration gas concentration Time interval of confidence beep (6 to 90 seconds). Annex Cleaning Give the MICRO III a short sight check after use. Use a damp cloth to remove stains or soiling from the casing. Never use solvents or cleaning agents! 17
Service and repair Service stands for maintenance, inspection, and repair of gas warning equipment. The function test must be done at least once a year and checks: The charge status of the battery The indication and, if necessary, the adjustment with zero gas and standard test gas The activation of gas alarms, e.g. With alarm test gas The response time This test has to be done by an expert, and a written confirmation must be filed. In case of repairs, only genuine spare parts are to be used, and the manufacturer s instructions have to be adhered to. Maintenance and inspection Maintenance and inspection describe those measures, which retain the nominal status of the MICRO III. They include a regular check and adjustment of sensitivity and zero point. In addition to this, the working order of the detector is to be checked as well. Make the MICRO III pass a test before it is being used. This test checks: The charge status of the battery, The display with zero gas and with test gas, The activation of gas alarms. 18
