(Item 29) and gasket (Item 28).
3] Remove battery, and clean any
corrosion from the battery terminals
(to protect terminals from corrosion
or condensation coat the terminals
with petroleum jelly).
4] Install the new battery.
5] Check gasket (Item 28) for damage
(replace if required). Position gasket
(Item 28) and cover plate (Item 29)
correctly, insert the screws and
tighten.
Display Operation
All meter operations are reflected in the
readout on the face of the meter. The
readout contains three lines of
information; refer to Fig. 7.
Note: The calibration is preset and is
permanently stored in the meter’s
computer.
The meter will turn on automatically
when the liquid flows through the
meter. The meter can also be turned on
manually by pressing and releasing the
display button.
Turn Off
The meter turns off automatically two
minutes after flow stops. When the
meter is off, the readout is blank.
Batch Total
The resettable batch total indicates flow
during a single use. This total can be
reset by holding down the display
button for three seconds until zeros
appear. The batch total can be found by
pressing and releasing the display button
until the bottom line displays “Total 2”.
Cumulative Total
The cumulative total is the total of all
the liquid measured since the meter’s
power supply was connected. This total
cannot be manually zeroed, but will
zero when the battery has been
removed, goes dead, or when it
reaches the maximum value of
999,999.
The cumulative total can be found by
pressing and releasing the display
button until the bottom line displays
“Total 1 Locked”.
Flow Rate
The flow rate is the rate the fluid is
flowing through the meter. The flow
rate setting can be found by pressing
and releasing the display button until
the bottom line displays “flow rate”.
Propeller
Any time liquid flows through the
meter, a small propeller displays.
Battery Replacement
Your meter is powered by a 9 volt
lithium battery. (Replacement batteries;
Lithium U9VL, Alkaline 522 or
MN1604). If the meter’s readout should
become dim or blank, the battery
should be replaced.
When the battery either falls or is
disconnected the batch and cumulative
totals return to zero. The factory
calibration is retained in the meter’s
computer permanently and will not be
affected by battery failure.
Auxiliary Facilities
Connection of an external 12 volt DC
power supply facility;
1] Remove the 4 large screws (Item 30)
and remove the register from the
coverplate.
2] Disconnect the internal battery.
3] Solder the external power leads to
the terminals marked ‘Ext 12V’ on
the registers printed circuit board.
4] Re-assemble the register onto the
coverplate, replace the 4 screws
(Item 30) and screw firmly together.
Connection of external pulse output
1] Remove the 4 large screws (Item 30)
and remove the register coverplate.
2] Connect external signal lead. (Refer
Fig. 8)
Pulse O/P and Ext Power are the
connections located on the interface
PCB, to use this output a 1K resistor
will need to be soldered between the +
voltage of the external power input and
the + of the pulse O/P. Pulse signal
represents the output cabling to the
receiving instrument.
