Description 
 
The FGD4 Safe Area Gas Detector uses the latest infrared sensor technology to accurately detect Carbon Dioxide. These detectors must only be used in areas without a risk of the presence of explosive gases. The detector requires a three-wire connection consisting a power supply connection to power the infrared sensor and a two-wire industry standard 4-20mA current loop to convey the gas levels to a separate control unit such as the Status Scientific Controls LC Series. Under zero gas conditions 4mA is drawn from the supply, and under full scale gas conditions 20mA is drawn from the supply. The current varies linearly for gas levels between zero and full scale. 
 
Calibration of the FGD4 can be carried out simply by using ZERO and SPAN buttons inside the instrument provided that the concentration of the calibration gas is the same as that used for factory calibration of the detector (refer to the instrument calibration certificate for details). 
 
Alternatively, the purpose designed plug-in hand held configuration unit shown below may be used together with any appropriate test gas concentration. 
Configuration Unit 
 
The FGD4 is calibrated using a purpose designed plug-in hand held configuration unit. To carry out a calibration, the operator must open the front cover of the unit, plug in the configuration unit and then present zero and span gases to the sensor during the course of the calibration procedure. 
 
Note - These gas detectors are not certified for use in potentially explosive atmospheres and therefore must only be used in applications where it is known that potentially explosive gases do not exist.
