• Charging the NiMH Battery
For safety reasons, the NiMH battery is not sufficiently charged at
the time of shipment. Fully charge the NiMH battery prior to use.
Use the instrument and AC adapter for charging.
WARNING
Be sure to use the CA150 to charge the NiMH battery. Charge the NiMH battery
in an environment with a temperature within the range of 10 to 35°C.
Charging the battery at a temperature that is not in the range above may
result in an insufficient charge, solution leakage, or heating up.
• Charging Procedure
1
Connect the AC adapter to the instrument when the NiMH battery pack
is installed in accordance with the installation procedure.
2
Press the POWER key to turn on the power.
Press the CHARGE key to start charging.
(The CHARGE mark appears.)
3
The CHARGE mark disappears when charging is complete.
(To stop charging, press the CHARGE key again.)
CAUTION
• Performing generation or measurement is possible during charging,
but accuracy is affected by the heat generated by charging.
To ensure accurate measurement (generation), use of the charging function
at the same time is not recommended.
• For details on the effect of heat generation on accuracy
(adding of temperature coefficient), refer to the specifications.
• Performing generation and measurement after charging is complete
(after at least 2 hours have elapsed) is recommended.
• Usage Guidelines
Usage time differs depending on the source function.
Source output
5 V DC/10 kΩ or more
Approx. 10 hours
(Measurement: ON, 24V LOOP: OFF)
Tip
Charging NiMH Battery
Depending on the use condition of the main body of the instrument,
charging may aborted.
E.g.) When outputting 24 V DC (loop), press the CHARGE key again
if the load current is high. If charging is aborted again, turn the OUTPUT OFF and
try charging again.
