4. Cautions
- Screen may become unstable or mark an error if the meter is used near
noise generating equipment.
- Only use the meter according to this instruction.
- Use extreme caution when working with bare conductors or busbars.
- Do not operate the Meter around explosive gas, vapor or dust.
- Check meter operation by measuring a voltage already known.
- Use the right terminals, functions and ranges for your measurements.
- When the measurement range is not known, start with the highest.
- Do not exceed the maximum input values shown in the charts.
- Do not touch the terminals that are not in use when measuring circuits.
- When making connections, connect the common test lead fi rst and then
the live test lead and vice versa when unplugging, remove the live test
lead fi rst and then the common test lead.
- Before changing functions, disconnect the test leads from the tested
circuit.
-- Do not measure voltages greater than 600 V CAT III installations.
(Category III is for measurements performed in installations of buildings.)
- Do not operate the meter without the lid.
