Operation Section 1-Safety Take all the required safety procedures needed when working with power laser beams and wear protection glasses all the time! The laser beam must hit ONLY the sensor head front side. Avoid to incidentally expose the protected stainless steel stem to the laser beam as dangerous back-reflections can be produced! Never touch the sensor head as this part can reach 70 C of temperature! In the case the laser power density is close to the damage threshold of the head absorber coating, damages like coating discoloration or underlying beginning of metal melting could occur. In both cases consult LaserPoint 2-Starting the Instrument To switch on the instrument, keep the ON/Zero button pushed until the LCD shows the serial number and the model of your instrument (LP.X, where X = 1.5, 5.0 or 10), then release it (this step takes approximately 2 seconds). The instrument will also display the selected laser wavelength; two options are possible: CO 2 (10.6 m) or YAG (1060nm). The wavelength displayed the first time is random; to change it refer to Paragraph 10 of this section. 3- Auto-check Cycle When the ON/Zero button is released, the instrument starts an auto-check cycle during which both circuit and display are controlled and reset. During this cycle, the LCD shows all available segments of alphanumeric characters and the bar graph at full scale. Upon completion of this cycle, the LCD displays the last recorded value of measured power.. 4-Zeroing/Resetting Before starting the first measurement or a new one, the instrument needs to be zeroed; to do so, just push and soon release the ON/Zero button. The LCD displays CAL and the LED on the right side of the LCS, turns steady green for approximately 5 seconds. At this point, any previously recorded value is zeroed and the instrument is ready to measure. LaserPoint s.r.l. Cronos Instruction Manual All Rights are Reserved 4
5-Measurement Cycle Check the laser shutter is closed and the laser is on; align the probe to the laser beam path and start the measurement cycle by opening the laser shutter. The measurement starts automatically and the measurement time is shown by a count down displayed on the LCD starting by Run 8 down to Run 0. This step takes approximately 8 seconds. During the acquisition time the LED blinks green. The bar graph indicates the head temperature on an arbitrary scale. Avoid measurements while the laser is warming up or when it shows instabilities on a few seconds period, as they can be meaningless or misreading. Always keep the instrument steady and the beam well centred, in particular on conical probes; do not move it during the readings to avoid measurement errors. 6-Measurement Display As soon as the measurement is over the LED turns into steady red. Remove the probe from the laser beam: the display shows the actual power, and the remaining thermal capacity. If the bar graph is below full scale, one or more measurements can be carried out before the sensor head needs to be cooled. The following measurement can be executed after the LED automatic shuts off and this takes between 10 and 20 sec depending on probe model. To perform a new measurement go back to Paragraph 4. 7-Cooling the Head Should the probe reach its limit temperature, the LCD shows COOL and the LED blinks red. Put the absorber head (only the head!) into water to cool it down. When the temperature falls below its maximum allowable limit, the LCD displays the last measured value and when the bar graph shows few bars, accurately dry the absorber by dry and clean air; the probe is ready for new measurements. 8-Auto Off /Battery Warning As the battery pack is about getting exhausted, a battery symbol pops up on the LCD: it warns you have approx. 10 hours of residual power.

Note: to increase the battery life, the instrument automatically switches off after 5 minutes of stand by operation. However the last recorded value is not lost; to retrieve it, go back to Paragraph 2 and follow the instructions. After the internal auto check cycle, the display will show the last measured value. To intentionally shut the instrument off, keep the ON/Zero button pushed until the LCD shuts off (this takes approximately 4 seconds). 9-Out of Range Notice When the head is exposed to a source exceeding its full scale, the LCD shows ERR instead of a numeric value. 10-Wavelength Selection To select the wavelength of operation (from CO2 to YAG or viceversa), go back to Paragraph 2 (shut the instrument off), but keep the ON/Zero button pushed until the wavelength change appears on the display (this step takes approximately 7 seconds). At this point release the button and the instrument is ready for a new measurement.. The displayed value is the last recorded power measurement carried out at this wavelength setting. 11-Customer s calibration This instrument can be re-calibrated by the user to match a custom reference. Remove the plastic cover of the adjustment switch located at the right side of the instrument body. Zero the instrument as indicated in Paragraph 2 of this Operation Section and afterwards carry out a measurement of a known laser source. Shift the switch on + or if you need to increase or decrease the reading displayed on the LCD to match your reference. This is done by limited pushes on the ON/Zero key, until the desired power value is achieved on the display. Reset the switch to its middle position CAL and re-cap. The instrument is ready for new measurements. LaserPoint s.r.l. Cronos Instruction Manual All Rights are Reserved 6
Notice to European Union Customers: European Union Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC The European Parliament will enforce new Directives in 2006 concerning the disposal of electrical and electronic equipment such as the Monitoring and Control Instruments. The regulations place responsibilities on the instruments supplier and the purchaser/user. One of the actions required by suppliers is to inform users of their obligations. The present instrument has been assessed in accordance with the European Parliament Directive2002/96/EC on Waste Electrical and Electronic Equipment, usually referred to as the WEEE Directive. The WEEE Directive requires that the instrument is disposed of at the end of its useful life in an environmentally responsible manner. Parts and materials that can be re-used and/or re-cycled have been identified in order that the use of new resources and the amount of waste going for landfill can be minimised. The WEEE Directive requires that if you are replacing the instrument with a new equivalent product from the original supplier, then that supplier can collect the old item without cost to yourself. It is emphasised that this no-cost return option is only available when you purchase a new product of equivalent type that fulfils the same function. Please inform your supplier of your wish to have the old instrument collected when ordering the replacement. If you wish to dispose of the instrument without replacing it then the appliance must not be mixed with unsorted municipal waste. The crossed-out wheeled bin symbol on the unit label or unit packaging, as shown in the table below, indicates this requirement. You must ensure that the instrument is disposed of at an authorised treatment facility; details can be obtained from your local council. Your rôle is critical and will help to ensure that the Earth s resources are maintained and that as much re-usable and re-cyclable material as possible is processed. It will also ensure that landfill volume requirements are kept at a minimum and that hazardous materials are not buried thereby providing potential future problems for the environment and human health. Wheeled bin symbol and description The symbol apply to all LaserPoint electronic products placed on the European Market after August 13, 2005. LaserPoint will affix the wheeled bin symbol with a bar to appropriate products. The bar indicates that the product was placed on the market after August 13, 2005. The WEEE Directive comes into force in January 2006. LaserPoint s.r.l. Cronos Instruction Manual All Rights are Reserved 7
