12 CHARGING AND REPLACING THE BATTERY PACK
The level of the battery charge is viewable in the
top right corner of the display screen with the
battery symbol changing gradually from full to
empty. Should the battery be discharged, con-
nect your roughness gauge a soon as possible
to the charger supplied with the gauge.
Full recharging the battery pack takes at least
8 hours. The main switch must be in ON
position during the battery charging. There is no
recharging if the switch is in the OFF position.
Since the power supply unit incorporates a sys-
tem ensuring automatic regulation of the battery
charge, this unit can remain connected during
the measurement operations. Your roughness
gauge will continue to operate whilst the battery
is recharging.
Note
Do not leave the gauge unit unused for a long
period of time with discharged battery as it
could deteriorate. Check the charge level at least
every 30 days. Should the battery charge fall
below a given level, you won’t be able to switch
back the gauge. Do not replace the battery by
zinc-carbon or alkaline batteries as they might
blow up when attempting to recharge them, but
in any case be damaging to the battery if their
charge is low.
Whenever your gauge will be left unused and
stored over a long time, toggle the main switch
to OFF to disconnect the battery pack from the
electronics.
This procedure being similar to dismantling and
turning off the gauge, all preference settings
previously saved will be deleted.
The rechargeable battery can support a given
number of charge/discharge cycles before its
replacement by a new one from type NiMH, 8,4
V, 170 mAh, format PP3 (06960063) will be
necessary.
Procedure to access the battery pack:
– Remove the probe.
– Undo both socket head screws on the bot-
tom face of the gauge.
– Dismantle the upper case while paying a
special attention to the cables.
– Remove the battery pack from its location
and replace it by the new one.
Make sure both positive and negative
poles are not inverted.
Provided the replacement is made within a few
seconds, no data or setting value will be lost.
Otherwise each calibration value, header and
other significant data will be cancelled upon au-
tomatic resetting of the gauge.
