Brief introduction

These series have two models.

The 80000 is autorange and calibrated by 50Hz sine signal.

The 80000R is also antorange and can offer true RMS measurement.

Safety information

Read this operation manual completely before using the meter to ensure that you use the meter safety
follow the safety guidelines as below :

l

Use the meter only as specified in this manual; Other wise,the protection provided by the meter
maybe impaired.

l

Never measure voltage while the test leads are inserted into the current input terminals.

l

Do not use the meter if it looks damaged .

l

Inspect the leads for damaged insulation or exposed metal, check test lead continuity. Replace
damaged leads.

l

Disconnect the power and discharge all high-voltage capacitors before testing in resistance, continuity,
and diode function.

l

Be Cautions when working above DC 60V or AC 42V,such voltages may cause a shock hazard.

l

When making measurement, keep your fingers behind the guards plant on the probes.

l

Select the proper function and range for measurement, To avoid damaging the meter, disconnect
the test leads from test points before change function.
