ETS-Lindgren HI-4433-STE Electric Field Probe - Manual (Page 24)

24 | Operation
ARM/OFF
The ARM/OFF switch activates and
deactivates the probe. In the ARM
position, the probe is powered by its
internal 3.6 VDC NiCd battery: in the
OFF position, the probe is inactive. To
prolong battery life, set the ARM/OFF
switch to OFF at the end of a test
sequence or when the probe is not in
use.
Charger
Each HI-4433 probe contains a
rechargeable nickel-cadmium (NiCd)
battery. A fully-charged battery
(nominal output voltage of 3.6 VDC)
provides up to 17 hours of continuous
operation.
ETS-Lindgren charges the internal NiCd battery of the HI-4433 at the
factory in order to calibrate the probe prior to shipment. While every
effort is made to ensure that your probe arrives ready to use, we
cannot guarantee that this will be the case. Always check the
condition of the battery prior to making any measurements.
A standard fast charger is supplied with the HI-4433. When charging is
complete, the fast charger acts as a trickle charger.
