MEASURING DC VOLTAGE
Ꮨƽ Warning
Do not measure voltage higher than 600V. Doing
so may damage the meter’s internal circuitry. If
the voltage is over 1000 VDC, the beeper will
sound continuously, indicating an over-range
measurement.
(1) Set the function switch to the position.
(2) Plug the black and red test leads into the
– and + input terminals, respectively.
(3) Touch the black test lead to the lower-
potential point of the circuit under test, and
the red test lead to the higher-potential point.
(4) Read the measured voltage on the display. If
the test leads are reversed, a minus sign will
appear to the left of the displayed value.
