1. SAFETY INFORMATION
The circuit under test must be de-energized and isolated before
connections are made except for voltage measurements.
Verify operation prior to measuring hazardous voltages (voltage
above 30V AC rms, 42V AC peak and 60V DC).
Do not touch the Circuit connections during a test.
Disconnect the hot test lead before disconnecting the neutral
test lead.
After insulation tests, to protect against electric shock, capacitive
circuits must to be discharged.
Do not use the meter if the low battery indicator (
displayed.
Test leads (including crocodile clips) must be in good order,
clean with no breaks or cracks.
Do not use the meter if it looks damaged.
Do not use the meter around explosive gases, vapors or dust.
Do not push the test button before all connections and
preparations are complete. The instrument must only be used by
suitably trained and competent persons.
Do not use the meter with any parts or cover removed.
Do not use the meter in a wet environment.
