Input Capture– Input Capture is used to match the device input and output zero and full scale
to a known value.
Adjust input sensor to 0% value to TDZ
3
or THZ
3
and follow the screen instructions. This
will set the device’s output to known 4mA value. Adjust input sensor to 100% value to
TDZ
3
or THZ
3
and follow the screen instructions. This will set the device’s output to a
known 20mA value.
Variable Trim– This menu allows you to view the following options Device Variable Trim,
Device Variable Trim Reset, and Display Device Variable Trim. Refer to Figure 4.15.
AO Trim– Directs you to a sub-menu. Here you can select Reset Trim, Trim Zero or Trim Full.
AO Trim Reset– Directs you to a sub-menu. Here you can select No or Yes.
Loop Test– A loop test may be performed in order to check output performance and accuracy
and to trim other instruments in the loop. Your output will be a current value, in mA, equal
to the value you input. You can check the other current devices on the loop and calibrate
them to this signal.
Input Simulation – Allows you Clear or Set a simulated Input.
S1 Corrosion Detection – This captures the nominal resistance value of Sensor 1, then
allows setting 2 threshold resistances (warning and alarm) to identify when corrosion
occurs. This applies only to Thermocouples and 3W and 4W RTDs. See section 1 for
more information on Corrosion Detection.
S2 Corrosion Detection – This captures the nominal resistance value of Sensor 2, then allows
setting 2 threshold resistances (warning and alarm) to identify when corrosion occurs.
This applies only to Thermocouples and 3W and 4W RTDs. See section 1 for more
information on Corrosion Detection.
Unlatch Range Alarm– This allows you to select and reset an actively latched range alarm
(1-4) provided that the input has returned to a non-alarm level.
Note: The Unlatch RA* menus are only visible if Advance Settings is Enabled.
Note: After making all desired changes enter SEND to update the unit.
