probes, and rotate the RANGE switch to the next lower position.
Reconnect the test probes, reapply power, and read the voltage on the
LCD display. If the RANGE switch is already on the lowest position
(i.e. 200mV DC), no greater measurement resolution can be obtained.
7.2 AC Voltage Measurement:
WARNING!
If the magnitude of the voltage to be measured is unknown, always start
by setting the meter to the highest range, and then to lower ranges,
until a satisfactory reading is obtained.
Do not rotate the RANGE switch with the input applied to the meter.
If the input voltage is higher than 500VAC, or exceeds the limitations
of a CAT I 600V measurement, do not attempt to measure!
WARNING!
This meter will display voltages that exceed the maximum voltage that
can safely be applied to the meter. The fact that the meter displays the
voltages does not mean that it is safe to measure these voltages.
7.2.1 Connect the black test lead to the
COM
jack and the red test lead to
the
V/ Ω /mA / F
jack.
7.2.2 Set the RANGE switch to a
V
~
position. If the magnitude of
the voltage is unknown, set the RANGE switch to the
500 position. If the input voltage is higher than 500VAC, do not
attempt to measure!
7.2.3
With power disconnected from the circuit to be measured, connect the
test probes to the measurement points. Apply power to the circuit.
The LCD will display the AC voltage.
7.2.4
If the display indicates overrange, i.e. "1- - -", remove power from the
circuit, disconnect the test probes, and rotate the RANGE switch to
the next higher position. Reconnect the test probes, reapply power,
and read the voltage on the LCD display. If the RANGE switch is
already at the highest position (i.e. 500VAC), the input voltage
exceeds the measurement capability of the meter and should not be
measured.
