Recorder Output Operation
The output at the recorder output terminals is a 4 - 20 mA signal for each
active channel that is proportional to the detection range of the channel. A
channel that is set as CHANNEL NOT USED or CHANNEL DISABLED in
the Channel Control & Setup Program (see “Chapter 5: Channel Control
and Setup Program” on page 28) has an output of 0 mA.
There are several special circumstances where the recorder output will
behave as follows:
• When a channel is in WARMUP after the Rig Monitor is turned on, the
recorder output will be at 4 mA.
• If the Rig Monitor is being powered by a battery and is in low battery
alarm, the recorder output for each channel will be 0 mA.
• When a channel is added or a channel type changed, the display will
indicate NEEDS CALIBRATION for that channel when the Rig Monitor
is first turned on and will continue to indicate this until the channel is
calibrated. In this situation, the recorder output will be at 3.2 mA until
the channel is calibrated.
• If a channel goes into a fail condition, the recorder output will be 0 mA.
• If you enter any of the instrument programs, such as the Calibration
Program, the recorder output will hold at the value it was at when you
entered the program was entered until you return to normal operation.
