Meter Operation
Asleep / Awake Mode
Asleep is a battery-saving mode in which the display
goes blank after two minutes of inactivity during normal
operation. The display comes Awake from sleep mode
when any button is pressed.
High/Low Flow Rate Indicator
The electronic meter dispenses fluids at two different
rates.
As the trigger is partially engaged, the flow rate is low
and is indicated by two bars on the display. See F
IG. 9.
• When the trigger is fully engaged, the flow rate is
high and is indicated by four bars on the display.
See F
IG. 10.
Battery Life Indicator
On the right side of the display is a series of four bars
located under the word BATT. See F
IG. 11. The pres-
ence of all four bars indicates a fully charged battery.
The bars decline in number as the meter is used and the
battery discharges. All Matrix meter batteries should be
re-charged at the end of the working day to assure good
performance the next work day.
• Batteries can be recharged at anytime without
battery damage.
• At one bar on the display you will have about
20-40% of the charge remaining.
• If a meter is removed from service for an
extended time the battery should be removed
and recharged.
• If you see the message “Remove Low Battery -
Wait 30 Seconds Then Replace”, remove the
battery, wait 30 seconds, and then replace it
with a charged battery.
• Even when a meter is idle (asleep), the meter is
still functioning and the battery will be used.
