Service and Maintenance
If the calibration of the TRICOR Mass Flow Meter shall be checked without adjusting the reading, just compare
the TCM reading with the reading of the reference meter at the desired flow rates.
If the TRICOR shall be adjusted according to the test results, make a test run (or better several tests runs) at
about 50% of the TCM full scale flow.
Read the current TCM meter variable:
CALIBRATION MENU
METER VAR.
UP DOWN EXIT
P
SET METER VAR
196.0
RIGHT UP EXIT
Calculate the new meter variable as:
METER_VARnew = METER_VARold * Reference_reading / TCE 8000_reading
If you made several test runs, use the average meter variable.
Use the keys
“RIGHT” and “UP” to set the calculated meter variable and confirm with “P” or skip with “EXIT”.
The display returns to the CALIBRATION menu.

Global Device Password
In order to protect the TRICOR Mass Flow Meter from unauthorized access, a user-specific password can be
set. It protects the access to all configuration menus. The password can be set either through the local display
as described below or through the Modbus interface (see TCM_COMO_S_EN_150408_E004, TRICOR Modbus
RTU manual).
NOTE:
If the global access code gets lost, the meter must be returned to KEM/AWL for resetting it. Resetting the code
onsite is not possible!
