1.9.2 Implications for Troubleshooting
The microprocessor will detect various component faults and out-of-range
conditions, and subsequently drop the output signal to 0.0 mA. When a fault is
detected, both relays will be deactivated as well. However, it cannot detect simple
out of calibration conditions, which can only be detected by applying a gas
standard.
2. Function and Configuration
2.1 Menu Structure and Use
Note: While the keypad functions are available without opening the case. It
is necessary to open the case to apply the calibration gases. The
‘keypad’ switches are located in the upper right side of the enclosure
