Setting Error
Processing
The Series 1 user program includes an Error Processing menu that
may be used to specify how the recorders/analog outputs and the
alarms respond to Range, Signal and Calibration errors.
The meter categorizes range errors as Under Range if the input
signal goes below the probe calibration range or Over Range if the
input signal goes above the probe calibration range. However, signal
errors are always categorized as Over Range, while calibration
errors are always categorized as Under Range.
Note: See Chapter 2 in the Service Manual for a detailed description
of Range, Signal and Calibration Errors.
When an error condition occurs, the meter displays an error message
on the screen and it drives the recorders/analog outputs and alarm
relays as indicated in Table 3-10 below.
IMPORTANT: The factory default setting for Error Messaging is
ON, but the factory default settings for both Under
Range and Over Range errors is
Ignore (this forces
the recorder/analog outputs to 0 mA or 0V).
Procedure for Setting
Error Processing
The Series 1 user program allows you to turn Error Messaging either
ON or OFF. In addition, if Error Messaging is ON, you can program
separate Over Range and Under Range responses for all alarm relays
(if installed) and recorder/analog outputs. The error responses are
independently programmable for each channel.
Table 3-11 on the next page provides instructions for entering the
Error Processing Menu, and Figure 3-17 on the next page shows a
typical menu screen. To suppress or activate the Display Messages
function, move the pointer to the Display Messages line and use the
ACTION menu key to select ON (the default) or OFF.
If Display Messages is set to
ON, use the steps on the next page to set
up error processing:
