Electrical Tester
Instruction Manual
Safety Information
Never use the tester if it or its test leads appear damaged.
Never apply more than 1000V DC or 1000V AC rms. between any
terminal and earth ground.
It is indicates terminals dangerous voltage present if the LED turns
on.
When using the probes, do not touch the metal probe tips.
Disconnect the live test lead before disconnecting the common test
lead.
Before each use, verify the tester’s operation by measuring a known
voltage.
Automatic Operation
The tester automatically turns on when you place the probes across a
complete circuit. The tester selects continuity or DC or AC voltage mode
based on the resistance or voltage between the probes. The tester
automatically turns off when you remove the probes from the complete
circuit.
Measuring Voltage
Connect test leads across the source or load under measurement, the
LED turned on at between 70% and 100% of their rated voltages.
DC Voltage AC voltage
220V DC maximum 690V rms. Maximum 45 Hz to 66 Hz
Testing for Continuity
Turn off circuit power before testing. Beeper indicates shorts lasting 1ms
or longer
OPEN short or 0-85KΩ
