CRC System Calibration and Service Adjustments
CAUTION: THE CALIBRATION, ADJUSTMENTS, AND DEFAULT
VALUES WILL AFFECT OPTIMUM OPERATION OF THE
EQUIPMENT. THESE VALUES ARE SET BY THE
MANUFACTURER AND SHOULD NEVER REQUIRE
MODIFICATION. IF SYSTEM PERFORMANCE INDICATES
THAT CALIBRATION IS NECESSARY, CONTACT THE
BEARCAT SERVICE DEPARTMENT BEFORE PROCEEDING
WITH ANY CALIBRATION OR ADJUSTMENT.
To change the calibration and default values, proceed as follows:
a. On the Console Display press “next” until you reach the Settings
Menu.
b. Press Select until “Cal-1” is
highlighted then OK.
c. On the Calibration page
press “select” until the
desired “G-Cal” or “F-Cal”
box illuminates yellow.
d. Press “edit”.
e. Press up or down to change
the setting.
f. Press “OK”.
FCAL footage calibration. A setting of + 1 raises the measured footage by
1 part in 1000. A setting of 2 lowers the measured footage by 2 parts in
1000, etc.
GCAL Pump calibration (Gallons Calibration); raises or lowers measured
pump rate by a factor of GCAL/ 1000 (like FCAL).
Equalizer Valve Packing
The three equalizer valves shown require periodic tightening of packing
nut. Under the packing nut is graphite rope packing that seals the valve
shaft. Over tightening of the packing nut can seize the shaft and prevent
movement. If a leak cannot be stopped it is time for new shaft packing.
Remove the packing nut, clear out old graphite rope packing and replace
with new. The “K” valve also has similar packing.
