conditions.
The options are: 0% through 100% in 16 steps.
LCD Flash on Error
This menu line allows the user to select the LCD and Select button to flash when an error is
reported. The options are:
• Off — no flash
• On — LCD and Select button flash when errors are reported.
Channels in Use
This menu line allows the user to select the appropriate number of measuring channels that
should be enabled for use in the installation.
The minimum allowable number is 1; the maximum number is 12.
Recover from Fault

rectified. The options are:
