1-2 Warning Messages for Safety
WARNING
1. Check the measurement type (insulation resistance, DC or AC
voltage) before measurement and select the appropriate
function for it.
2. Do not apply a voltage or signal exceeding the specified
maximum allowable input. (For the maximum allowable input
voltage value, see section 1-3 on the next page.)
3. Do not open the case or battery cover unless replacing the
batteries as described in this manual.
4. Always use the test leads specified in the manual.
5. If the insulation coating of a test lead is damaged or its
conductor wire is exposed, do not attempt to repair it.
Instead, replace with a new test lead.
6. Do not switch the measuring function during measurement.
7. Do not use the instrument when it is moistened, when your
hand is wet or when the ambient humidity is high (85 %RH or
more).
8. Do not touch the metallic parts of the test leads during
measurement.
9. Do not use the instrument if it is defective and incapable of
making the specified measurements.
10. Do not use the instrument using high-power or higher voltage
circuitry than the maximum allowable input.
11. Be sure to conduct annual inspections.
