Field Calibration Procedures
(Correction Factor Method)
1. To calibrate, press and hold the CALIBRATE
and DISPLAY buttons for about 3 seconds
until you see FLdCAL. Release both buttons
and you will see CF - 00.0. You are now in
the field calibration mode and values from
-99.9% to +99.9% can be entered.
+
2. The /– position appears either as an
"underscore" character for plus, or as a
"hyphen" character for minus. The DIS-
PLAY button selects the position and the
CALIBRATE button toggles this character.
3. The DISPLAY button can then be pushed
to select the numeric positions. Press the
CALIBRATE button to scroll from 0 to 9.
Enter the percentage of change you want
the display to correct. When satisfied with
the value, press both CALIBRATE and
DISPLAY buttons simultaneously. CALEnd
will be displayed and unit will go back to
normal operation, less the FAC (factory
calibration) icon.
4. All enabled units-of-measure remain visible
and selectable – the entered correction will
be applied to all enabled units.
5. To return to factory calibration (FAC), press
and hold both CALIBRATE and DISPLAY
buttons for about 3 seconds until FAcCAL
is displayed. Then release buttons. Unit
should return to normal operation and FAC
icon is visible.
Calibration with Conditioned
Signal Output Module
The K-factor of your meter appears on the
calibration report as the number of pulses per
gallon. The factor is determined during produc-
tion using water at 70° F (21° C). This K-factor
may be used for "single point" calibration
and provide acceptable accuracy. However,
readings may not be accurate when using this
calibration method in some situations. For
example, extreme temperature conditions,
non-standard plumbing configurations or with
fluids other than water.
MAINTENANCE
Proper handling and care will extend the life
and service of the meter.
Turbine Rotor
The meter is virtually maintenance-free. How-
ever, it is important the rotor moves freely. Keep
the meter clean and free of contaminants.
If the rotor does not turn freely, apply a pene-
trating lubricant on the rotor, shaft and bearings.
Remove any debris or deposits from the rotor
using a soft brush or small probe. Be careful
not to damage the turbine rotor or supports.
CAUTION
Blowing compressed air through the tur-
bine assembly could damage the rotor.

Battery Replacement

The computer display is powered by two
3-volt lithium batteries which may be replaced
while the meter is installed. When batteries are
removed or lose power, the batch and cumula-
tive totals and the field and factory calibrations
are re tained.
If the display becomes dim, blank or the low
battery message appears (see below), replace
the batteries as follows:
1. Remove the four Phillips-head screws from
the face of the meter and lift the faceplate
from the turbine.
2. Remove the old batteries and clean any
corrosion from the terminals.
3. Install new batteries. Make sure the positive
post is in the correct position.
4. When the batteries are replaced, the face-
plate will power ON. Check the display to
ensure normal functions have resumed
before assembling again.
5. Reseat batteries, if necessary, and posi-
tion the faceplate on the turbine housing.
To avoid moisture damage, make sure the
seal is fully seated. Tighten the four screws
on the faceplate.
