Preset Meter Operation
The preset operation of the meter is designed so the
trigger latch is released when the preset value is
reached, which causes the fluid flow to stop.
In order for the preset mechanism to operate correctly,
the user must latch the trigger and release the trigger
during each dispense.
Holding the trigger in the open position overrides the
preset functionality of the PM8/PM20 meter.
For additional operation directions, refer to the
, page 12, and the instructions on
page 13.
Activate the Meter
The meter can be activated by pressing any button or
by running fluid through the meter (F
. 3).
Press the Reset key to clear the meter before starting a
new dispense cycle. This is the best way to activate the
meter, because a second press also clears the quantity
of the last dispense cycle.
NOTE: The meter goes blank after approximately one
minute of non-use.
When activated, the meter displays the last completed
dispense quantity. Additional fluid may be dispensed,
increasing the total.
Pressing the Reset key advances the meter to the
Default Preset value, which is user definable through
the Setup Mode. The meter displays the Default Preset
value (factory default value is 4.0).
Pressing the Reset key again advances the meter so
that the Preset amount may be configured. The display
value is 1.0.
Preset Value Configuration
After reaching the Preset configuration screen, the
value may be increased using the 10, 1.0, and 0.1 keys.
After configuring the desired Preset value, fluid flow
may be commenced. The meter updates until the
Preset amount is reached. When fluid flow begins, the
value displayed changes from the preset value to the
amount dispensed, beginning with 0.0.
Function of Reset
Press the Reset key to clear the quantity of the last
dispense cycle and to reset the meter to the Default
Preset value (F
. 3).
Setup Mode
Press and hold the Reset button for approximately six
(6) seconds. All LCD segments and LED of the digital
display illuminate. The software revision displays for
approximately two (2) seconds. The LCD briefly goes
blank then displays AddL. The meter is now in Setup
Mode.
