Page 8: Powering The Unit
Oxygen Transmitter – Manual CO2Meter.com iSense Oxygen Transmitter – Manual CO2Meter.com Powering the Unit LCD Display The unit can be powered by hardwiring 24 VDC power through the The Liquid Crystal Display (LCD) screen shows the following features: MDCM‐4FP‐2M Cable (included) but sampling units can also be CO2 in percentage format (##.##%) for 100% powered by the included 24VDC International wall power supply. Theory of Operation The zirconia oxygen sensor utilizes solid‐state electrochemical reactions to produce a voltage proportional to the current oxygen. This voltage is then digitalized and filtered to a usable value. The oxygen sensor has also been factory calibrated to meet specifications. Calibration The calibration process varies depending on the type of unit and whether it has optional data logging functionality or not. All units are factory‐calibrated with multiple reference points of gas, and have been verified to be accurate within their specific functionality before shipment. However, if the unit is severely jolted or otherwise mechanically disturbed, the sensor can drift requiring recalibration. All calibration procedures follow a single‐point calibration routine that effectively shifts the zero‐point of the O2 sensor. ... -
Page 9: Calibrating Using Modbus Or Pc Connection
Oxygen Transmitter – Manual CO2Meter.com iSense Oxygen Transmitter – Manual CO2Meter.com Calibrating using MODBUS or PC Connection You can Download the software directly and free from this link in our website. (http://www.co2meter.com/pages/downloads) More precise calibrations can be performed using the PC connection. The unit can be attached to a PC using an optional USB to RS‐485 cable, available on our website, or via a mini‐USB cable to the internal USB connection. Using the USB cable you can connect the unit to the computer and start configuring through the software GasLab ®. Calibration of the Oxygen Sensor In the desktop software application O2 can be calibrated individually. The O2 sensor can be calibrated to 0% and then to 20.9%. During normal operation 0% calibration of the oxygen transmitter should not be necessary. Calibration can also be performed over MODBUS, see additional documentation for MODBUS registers. Calibration can be performed using either 0% CO2 calibration gas (typically nitrogen, Argon, etc.), or using a fresh source of air, assumed to be approximately 20.9% O2. Attach calibration gas to the unit and connect the unit to a personal computer. Open the calibration screen in the GasLab ® software. Click ... -
