1. SAFETY INFORMATION

Do not operate the tester if the body of meter or the test lead look
broken.
Check the main function dial and make sure it is at the correct position
before each measurement.
Do not perform resistance and continuity test on a live power system.
Do not apply voltage between the test terminals and test terminal to
ground that exceed the maximum limit record in this manual.
Keep the fingers after the protection ring when measuring through the
test lead.
Chang the battery when the

symbol appears to avoid incorrect

data.

Environmental Conditions

Operation Temperature: 0°C to 40°C(32°F to 104°F); < 80 % RH
Storage Temperature: -10°C to 60°C(14°F to 140°F); < 80 % RH

Explanation Symbols

Attention refer to operation Instructions.

Dangerous voltage may be present at terminals.

This instrument has double insulation.

Approvals:

EN61010 300V CAT IV

2. GENERAL SPECIFICATION

Digital Display:

4 digital liquid crystal(LCD), Maximum reading 5000.
