input terminals beforehand, press ZERO to automatically subtract the value
measured when the testing leads are short-circuited from the reading.
● For high-resistance measurement (>1MΩ), it is normal to take several
seconds to obtain a stable reading.
● To avoid harms to you or damages to the Meter from eletric shock, do not
attempt to input voltages higher than 33V AC or 70V DC.
● When resistance measurement has been completed, disconnect the
connection between the testing leads and the circuit under test and remove
testing leads from the input terminals.
Testing for Continuity (see gure 5)
Warning
To avoid damages to the Meter or to the devices under test, disconnect
circuit power and discharge all the high-voltage capacitors before
measuring continuity.
To test for continuity, connect the Meter as follows:
1. Insert the red test lead into the VΩHz terminal and the black test lead into the
COM terminal.
2. Set the rotary switch to and press SELECT button to select
