Caution
To avoid possible damage to the meter or to the equipment under test, follow these guidelines:
‐ Disconnect circuit power and discharge all high voltage capacitors before testing resistance, insulation
resistance, and test for continuity.
‐ Before rotating the range switch to change functions, disconnect test leads from the circuit under test.
‐ Remove test leads from the mater before opening the Meter case.

GENERAL DESCRIPTION
This instrument is accurate, reliable and easy to operate. For insulation resistance test, you can change the test
voltage among 250V, 500V and 1000V. It can also be used to test ACV, resistance which is lass than 200

, and
fest for continuity. You can use it to test transformer, motor, cable, switch, electrical appliance as well as to do
insulation resistance test.
