BATTERY RECHARGE AND REPLACEMENT
The meter displays the remaining battery percent-
age when turned on. When the level is below 5%,
the battery symbol on the bottom left of the LCD
blinks to indicate a low battery condition.
If the battery level is low enough to cause erroneous readings, the Battery Error
Prevention System (BEPS) turns the meter off.
The 9V battery provided with the instrument can be recharged using the
optional
HI 710040
battery charger.
Plug the recharger and the green LED will turn on, then put the meter on the
recharger and the LED will turn to orange, to indicate that the battery is
charging.
It will take approx. 14 hours to completely charge the battery.
The supplied 9V Ni-MH recharge-
able battery can last for about
5 years. When the battery needs
to be replaced, remove the cover
on the rear of the meter and
replace the rundown battery with
a new one, while paying atten-
tion to the correct polarity.
Reattach the back making sure
that the gasket is in place and
tighten the 3 screws to ensure a
good seal.
Replacement should take place in a non-hazardous area using a 9V Ni-MH
rechargeable battery.
Note:
The meter can also be powered with a normal 9V alkaline battery.
NEVER USE THE HI 710040 CHARGER WITH NON-RECHARGEABLE
BATTERY
.
Note: Dispose of the Ni-MH battery according to local regulations.
