2. .When testing DC voltage, if the probe L2 is connected to the
positive pole of the tested object and L1 is connected to the
negative pole of the tested object, the LCD will display the
corresponding voltage. Otherwise, the LCD will display "-". To
determine the positive and negative poles of the object being
tested, connect either probe to the object being tested. If the
"-" symbol on the LCD of the tester is not lit, it indicates that the
end connected to L2 is the positive pole, and the other end
connected to L1 is the negative pole.
3. When testing AC voltage, the two probes can be connected
to either end of the object being tested. The LCD displays "AC"
and the corresponding voltage value as well as the frequency of
the tested AC voltage.
Note: When testing AC voltage, the screen may display L and
R , and the phase sequence indication at this time is an
uncertain state. The L symbol or R symbol may be displayed,
and even be displayed alternately. Only when testing
three-phase power systems can the symbol L/R be displaye
correctly and stably.
Warning
This instrument cannot test voltage for a long time. If it is
necessary to test for a long time, it is necessary to follow the
requirement of disconnecting the test for more than 240
seconds after testing for more than 30 seconds.
