IM CW500-02EN
Power Supply
The CW500 can run on AC power or batteries.
Installing Batteries
Even when AC power supply is cut off such as due to a power failure, the
power supply can be switched to batteries to continue measurements.
AA alkaline batteries (LR6) or AA nickel-metal hydride batteries (Ni-MH)
can be used.
For rechargeable batteries, use the battery manufacturer’s charger to
charge them. You cannot charge the batteries with the CW500.
* The batteries included with the CW500 are AA alkaline batteries (LR6).
WARNING
● Never replace the batteries while measurement is in progress.
● Insert batteries with the correct polarity. Otherwise, the
batteries may leak, heat up, or burst.
● Do not mix new and old batteries or mix different brands or
types of batteries. The batteries may leak, heat up, or burst
due to their characteristic differences.
● The power inlet when the instrument is running on batteries is
isolated, but never touch it.
● When replacing batteries, be sure to turn the power off, and
remove the power cord, voltage probe, and current clamp-on
probe from the CW500.
CAUTION
● If you do not intend to use the instrument for a long time,
remove the batteries from the instrument. Leaving the
batteries in the instrument may cause the batteries to leak.
● If the batteries go flat during use, the measurement data will
not be saved. We recommend that you replace the batteries
as soon as they start to run low.
