MAINTENANCE
Do not perform any service by yourself. Service should only be done by qualified personnel and
trained technicians.
Service
If the instrument fails to operate, check battery and test leads. Replace them as necessary. If
the instrument still cannot work, verify with the operating instructions to make sure correct
procedures are followed.
When servicing, use specified replacement parts only.
Note: The meter must be completely turned off while replacing the battery. Refer to “Installing
Battery” section for details.
Cleaning
To avoid electrical shock or damaging the meter, prevent water from getting inside the case. In
the case that water gets inside, remove the battery immediately and do not operate the
instrument immediately. Doing so will immediately damage the instrument and void its
warranty.
Before cleaning this meter, make sure the power is OFF and remove external AC adapter if one
is used. To clean the meter, wipe the dirty parts with a soft cloth soaked with diluted neutral
detergent. Avoid having the instrument too wet to prevent the detergent from penetrating
into the inside components of the meter, causing damages. After cleaning, make sure the
instrument is completely dried before operating it again.
