7.3.2
Set the RANGE switch to a
V
position. If the magnitude of the
voltage is unknown, set the RANGE switch to the highest
V
position.
If the input voltage is higher than the previously stated limits, do not
attempt to measure!
7.3.3
Connect the test probes to circuit being measured. The LCD will display
the DC voltage.
7.3.4
If the display indicates overrange, i.e. “1- - -”, disconnect the test probes
from the circuit and rotate the RANGE switch to the next higher position.
Reconnect the test probes to the circuit and observe the reading on the
LCD display. If the RANGE switch is already at the highest position
(i.e. 1000 VDC), the input voltage exceeds the measurement capability
of the meter and should not be measured.
7.3.5
If the displayed value is less than “200” (decimal point not shown), a more
accurate reading may be obtained by setting the RANGE switch to a lower
range. Disconnect the probes from the circuit and rotate the RANGE
switch to the next lower position. Reconnect the test probes to the circuit
and observe the reading 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.
7.4 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 750VAC (CAT I), 600VAC (CAT II),
or 300VAC (CAT III), do not attempt to measure!
Use Caution when measuring voltages above 30V AC.
7.4.1
Connect the black test lead to the
COM
jack and the red test lead to the
VOLT / OHM / BEEPER / DIODE / FREQ.
“
V
Ω

” jack.
7.4.2
Set the RANGE switch to a
V
~
position. If the magnitude of the
voltage is unknown, set the RANGE switch to the highest
V
~
position.
If the input voltage is higher than the previously stated limits, do not
attempt to measure!
