4. Batteries and accumulators
At works the PH-T is equipped with a 9V battery. This will last approx. 72 hours when
used for simulation (instrument test). When used for measurement (sensor test) or
high resistance test, power consumption is higher.
NOTE
The instrument does not indicate low battery.
The battery is accessible from the back of the instrument. Observe the safety and
environment regulations for handling, storage, and disposal of batteries.
The PH-T can be used with rechargeable batteries and provides a charging function.
For specifications of connection and current-supply please refer to the technical data.
The time necessary for recharging of a completely discharged accumulator depends
on the type and the capacity. It can be calculated as follows:
Ni-Cd
Charging time (h) = capacity (mAh) x 0.07778
Ni-MH
Charging time (h) = capacity (mAh) x 0.08333
ATTENTION
The PH-T does not automatically stop the charging process. Take care
not to exceed the calculated charging time.
CAUTION
Never try to recharge regular batteries!
