2.6 Power supply and
battery recharging
EHP-50F has an internal rechargeable Li-Ion battery that can be recharged
with the battery charger supplied with it.
Make a full charging cycle before using the Analyzer for longest battery
operation time.
ALWAYS connect the battery charger to the power supply BEFORE
connecting it to the EHP-50F.
The battery charger has an internal protective circuit that will limit the
output of current if there is any load when connecting to the mains.
Always remove the shorting loop connector when recharging EHP-
50F.
Battery charger:
output: DC, 10 - 15 V, ~ 500 mA

In order to safeguard the features of the batteries, it is crucial to have
a complete recharge before storing them for periods longer than 4
months. Therefore, it is warmly suggested recharging the batteries at
least every 4 months even though the device has not been used.
The minimum voltage level for operation is about 3.25V. The batteries
must be recharged for lower voltages. Below such voltage the
analyzer will turn OFF automatically.
The time required for recharging the batteries is about 4-5 hours.
When the recharge is complete, this is indicated by the Led of the
EHP-50F, with a rapidly blinking Green light.
To take measurements ALWAYS remove the battery charger from the
EHP-50F Analyzer otherwise the system does not work.
The battery status is reported by the EHP-50 control program
When charging is in progress the connection to the probe is not available.
