C.6.2a Setting Up Error Handling
This menu option lets you set how the XGS868i will handle the outputs for measurements and average (two-path)
measurements during an error condition. See Chapter 2,
Error Codes , in the Service Manual for a discussion of the
built-in error codes.
1. From the
Input/Output
option, highlight and double-click on the Error Handling option in the center pane.
2. Double-click on the desired Error Handling selection (as shown in Table 23 and Table 24).
a. If you selected Error Level in mA , enter the 4-20 mA Error Level (the number of milliamps the analog output
will put out during a fault condition). Enter a whole number between 0 and 22, and click
[Next Item].
See Table 23 and Table 24 for a description of the error handling options available and how the totalizers and display
respond to them for a single and two-channel meter.
For a one-channel meter, after responding to the above prompt, the meter returns to the
Global I/O
prompt shown on
page 113. For a two-channel meter, proceed to step 3 on page 115.

Error Level
in mA
Allows user to enter 4-20 mA error level in mA. Sends analog outputs to entered mA level
when a fault occurs.

Holds last “good” reading. Holds last “good” reading and continues
to totalize based on that “good” reading. Stops totalizing.
SUM Adds two channels using the
last “good” reading. Holds last “good” reading and continues
to totalize based on two channels. Stops totalizing if either or
both channels go into error.
DIF Subtracts two channels using
the last “good” reading. Holds last “good” reading and continues
to totalize based on two channels. Stops totalizing if either or
both channels go into error.
