Section.3 Sensor Set-Up (Configuring Settings) General Settings Applies to: Enter a name for the sensor, the scale, the sample rate and transmission rate. Sample rate This sets how often the sensor takes a reading. Note: This is not how quickly the sensor transmits the data. Frequency of sample transmission This sets how often the sensor transmits the information back to the PC. In the example above the sensor takes a reading every 0 seconds and logs this information on-board the sensor and transmits every minute. After 6 readings the sensor will transmit the information to the PC. (0 seconds x 6 readings = minute). key: Temperature and Humidity Sensor Temperature Sensor with Probe Temperature only Sensor WiFi Hints and Tips 6
Section.3 Sensor Set-Up (Configuring Settings) Temerature Alarm set-up. Applies to: Low / High Alarms You can set an alarm to be triggered once a sensor exceeds a high or low temperature. Note: If you try to set the low alarm higher than the high alarm (and vice versa) you will get an error message. Alarm Hold This will hold the sensor in its alarm state even when the temperature has returned to an acceptable range. For example if the High Alarm is set to 4 C and the sensor rises to 46 C it will trigger an alarm. If the sensor then drops down to 4 C and Alarm Hold is switched on, the sensor will remain in an alarmed state. If Alarm Hold is switched off then the sensor would revert back to its normal state. In this situation you can check missed alarms by reviewing the graph. key: Temperature and Humidity Sensor Temperature Sensor with Probe Temperature only Sensor WiFi Hints and Tips 7

Section 9.0 Power & Optimising Battery Optimising battery performance: The sensors can be powered in one of two ways: Internal Battery Power USB/Mains Power Battery Power These sensors contain rechargeable batteries. It is good practice to optimise your system to avoid excessive recharging cycles. To do this be aware of the following; 3 Transmitting uses a lot of battery power. By increasing the time between transmissions the batteries will last longer. For example; for a short battery life transmit every minute, for a medium battery life transmit every 0 minutes and for a long battery life transmit every hour. The sensor has an automatic sleep mode. The sensor detects when your PC is turned off or the software is closed, and enters a power-saving mode. In this mode the sensor wakes-up less frequently to test communications, but continues to gather data ensuring that no information is lost. When you turn your PC back on, it can take up to 30 minutes for the sensor to synchronize. This saves a lot of power. Under normal circumstances the sensor will synchronize within 5 minutes. If the sensor is mains powered, synchronization will complete within 5 minutes. Once communication is re-established the sensor returns to its normal transmission rate. USB/Mains Power If you have a critical process or do not wish to recharge sensors, you can opt to have the USB charger plugged in continuously. WiFi Hints and Tips 5
Section 0.0 Sensor Maintenance Reset / Restore Sensor Reset Sensor Warning: The sensor will retain all settings but will lose any data that has not been transferred to the PC. The sensor can be reset by holding the button for 0 seconds. Release the button when LOW is flashing in the top right hand corner of the display. Restore Factory Settings Warning: Only use restore when all other methods have failed. A factory reset can also be performed, hold the button for 0 seconds until appears on screen. Doing this will return the sensor to the factory state deleting all settings and clearing all previously recorded data.
