INSULATION TESTER

1. SAFETY INFORMATION

The circuit under test must be de-energized and isolated before

connections are made except for voltage measurement.

Verify operation prior to measuring hazardous voltages (voltage

above 30V AC rms, 42V AC peak and 60V DC).

AMB-25

Do not touch the Circuit connections during a test.

Disconnect the live test lead before disconnecting the neutral

test lead.

INSTRUCTION MANUAL

After insulation tests, to protect electric shock, capacitive circuits

must to be discharged.

READ

Caution refer to this manual before using the meter.

Dangerous voltages.

Meter is protected throughout by double insulation or

reinforced insulation.

Comply with IEC1010-1

When servicing, use only specified replacement parts.

HOLD

Do not use the meter if the low battery indicator (BT ) is

showed.

Test leads (including crocodile clips) must be in good order,

clean and no broken or cracked.

Do not use the meter if it looks damaged.

Do not use the meter around explosive gas, vapor or dust.

Do not push test button before all connection and preparation is

done. 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.
