4.4 SETUP MENU [SETUP]
The SETUP menu is used for one-time setup and for Diagnostics.

4.4.1 PMC 2000 (Manual) [SETUP \ 1 \ 2]
This menu is to calibrate the 2000 series controller for the particular PMC-2000 level transmitter
module located at the probe head. There are 3 calibration parameters: A, K, C. These values are
used to calculate the capacitance from the frequency signal received from the PMC-2000. The
parameters may be calibrated manually or automatically. Automatic Calibration is performed at the
factory on each PMC-2000 module. A label listing the A, K, C values is then affixed to the PMC-2000
connector. AUTOMATIC CALIBRATION IS ONLY TO BE PERFORMED BY AUTHORIZED
PERSONNEL AND IS BEYOND THE SCOPE OF THIS MANUAL. IF PROBLEMS ARE
ENCOUNTERED, OR IF THE A, K, C VALUES ARE NOT KNOWN, PLEASE CONTACT AN ARJAY
REPRESENTATIVE.
Manual entry of the A, K, and C values is described in Section 3.4.1
4.4.2 DIAGNOSTICS [SETUP \ 2]
This menu displays the received frequency signal from the PMC-2000 module at the probe head
and the calculated capacitance. Both of these values are useful in determining calibration or
performance problems.
****DIAGNOSTICS*****
12.04pF 4461.48Hz
1-4mA 2-20mA 3-Other
Pressing key 1 forces the mA output to 4mA. Similarly pressing key 2 forces the mA output to
20mA. Any other value between 0 and 20 may be set by pressing 3 for “Other” then entering the
desired mA output value.
This feature is convenient to check the performance of external recorders or PLC’s, which read
the mA output. The mA output reverts back to its actual level when the normal Display Menu is
selected.
4.4.3 SETTINGS MENU [SETUP \ 3]
This menu sets the digital filter and the engineering units. In addition the mA output may be
trimmed for maximum accuracy. Also the Tag number and Software revision may be viewed:

mA TRIM:
This procedure trims the mA output for maximum accuracy by compensating for the mA output
circuitry tolerances. THIS PROCEDURE IS PERFORMED ON EVERY TRANSMITTER AT THE
FACTORY AND IS TO BE PERFORMED BY AUTHORIZED PERSONNEL ONLY. IF
IMPROPERLY DONE, THE ACCURACY OF THE mA OUTPUT IS AFFECTED.
Under certain conditions this procedure may be undertaken in the field with Arjay’s permission:
