Charging the Battery
During periods of heavy use in a harsh environment, you will need to
recharge the battery after three hours of operation. Under better
circumstances, it may need recharging less often. The battery will last
longer if you recharge the instrument after each use.
When the battery charge is low, a lowĆbattery indicator
appears in
the upper right corner of the display. If the battery voltage drops below
7.32ĂV, the instrument automatically turns itself off.
In order to recharge the battery, plug in the External Power AC Adapter
and leave the instrument turned off for three hours.
NOTE
The 222PS batteryrecharges whenever you plug it into
external power. However, it recharges faster if the instruĆ
ment is off.
Charging the Battery Externally
You can charge the battery outside the instrument using the external
battery charger accessory. See the Optional Accessories information in
Appendix E. You can also use any other charger that supplies 9.8ĂVDC
at 20
_
C with the supply current limited to 1ĂA. For best results in
various temperatures, thermally compensate the charging voltage by
-10 mV per degree C.
For example, at 50
_
C, the charging voltage is
9.80 V + [(50 - 20)
-10 mV] = 9.50 V
To charge the battery, follow the steps on the data sheet that comes
with the battery charger unit.
Time Out
An automatic timeĆout feature prevents the battery from losing power
when the instrument is unattended for a long period. When you enable
the timeĆout feature, the 222PS turns itself off after two minutes of
operating under battery power with no changes to the controls.
