Calibration
Pneumatic Sensor Calibration
The LevelCom 100 performs a Hardware
Zero when the power is applied and
approximately every hour thereafter.
Calibration is not a routine maintenance
procedure. If you are not sure whether to
proceed with calibration please contact TMS
for guidance prior to adjusting the instrument.
This procedure must be performed by a
qualified technician.
Required Equipment
1. Calibration gauge accurate to at least
0.1" H
2
O (The gauge must have an
adequate range for the sensor in the
LevelCom 100).
2. Hand pump.
3. Fittings (1/8” NPT) and tubing to hook up
to the LevelCom 100.
Field Calibration Procedure
Note: This procedure assumes familiarity
with the LevelCom 100 program. If you
require assistance in entering the program
please refer to the programming sections of
the manual and the Configuration Flow
Chart. The CALIBRATE menu is an item in
the UTILITIES menu.
1. Determine the type of pressure sensor
installed in the LevelCom 100 by
inspecting the white silk-screened area of
the Pressure Sensor Circuit Board (Refer
to Figure 23 for the location).
2. Connect a fitting to PORT 1 DRAIN on
the LevelCom 100 if there is not already
a fitting in place (Refer to Figure 22 for
Figure 22 Bottom View of LevelCom 100
