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 figure 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 V Ω Hz terminal and the black test lead into the
COM terminal.
2. Set the rotary switch to and press SELECT button to select
