5.26 Diagnostics Menu [DIAG]
The diagnostics menu contains all of the user settings that are specific to the
system diagnostic functions, as well as functions that aid in troubleshooting
application problems.
Set Hold
The Set Hold function locks the current loop output values
on the present process value and holds relays in current
status. This function can be used prior to calibration, or
when removing the sensor from the process, to hold the
output in a known state. Once HOLD is released, the
outputs return to their normal state of following the process
input. The transfer out of HOLD is bumpless on the both
analog outputs - that is, the transfer occurs in a smooth
manner rather than as an abrupt change. An icon on the
display indicates the HOLD state, and the HOLD state is
retained even if power is cycled. Press ENTER to initiate
user entry mode, and entire value will flash. Use the UP
arrow key to modify the desired value, selections are
ON
for
engaging the HOLD function, and
OFF
to disengage the
function. Press ENTER to store the new value.
The Set Hold function can also hold at an output value
specified by the user. To customize the hold value, first turn
the HOLD function on. Press the ESC key to go to the DIAG
Menu and scroll to Sim Output using the UP arrow key.
Press ENTER. Follow the instructions under Sim Output
(see following page).
