5. Measuring Operations

5-1 AC Voltage and DC Voltage Measurement
Warning
1. Don't allow to measure any voltage in excess of 600V
r.m.s. DC or AC in case of electric shock or meter
damage.
2. Don't allow to apply any voltage in excess of 600V
r.m.s. DC or AC between meter and earth in case of
electric shock or meter damage.
3. Don't measure AC/DC voltages if a motor on the
circuit is being switched ON or OFF. Large voltage
surges may occur that can damage meter.
The voltage ranges of the meter are:
DC Voltage: 400.0mV, 4.000V, 40.00V, 400.0V, 600V;
AC Voltage: 4.000V, 40.00V, 400.0V, 600.0V.
The method of measuring voltage is:
1. Turn rotary switch to
V
2. Press key and select AC or DC measuring range.
FUNC
3. Apply the two ends of test leads to measure the
voltage value of circuit under test. (Paralleled with
circuit under test)
4. Read measured voltage value with LCD. When
measuring DC voltage, the display shall display the
voltage polarity connected with red test leads at the
same time.
Notice:
At DC200mV and AC 2V ranges and under non-input,
the meter shall have several readings because of
outside interference, but its normal usage and
measuring accuracy will not be affected.
