The value of the AC voltage measured with this meter is True RMS (root mean
square). These measurements are accurate for sine wave and other waves
(without DC offset), square wave, triangular wave and step wave.
3.2.2 Electric resistance measurement
To avoid the meter or the measured equipment from damage, do
not attempt a resistance measurement unless the operator has
already cut off all power sources for the circuit to be measured and
fully discharged all high-voltage capacitors.
Ohm is the unit of electric resistance ().
The measuring ranges of electric resistance of this meter are 600.0,
6.000k, 60.00k, 600.0k, 6.000Mand 60.00M,
Measurement of electric resistance
1. Turn the rotary switch to the position and press “FUNC/Hz” to
choose .
2. Connect the test lead in black and test lead in red to COM input socket and
V/input socket respectively.
3. Use another two ends of the test lead to measure the electric resistance of
the circuit to be measured.
4. Read the measured electric resistance value on LCD screen.
Notes:
The measured value of the electric resistance of the circuit differs a bit
from the rated value of the electric resistance.
To ensure measurement accuracy, in attempting a low resistance
measurement, first put two pen-shaped meters in short circuit and
capture the resistance reading of these short circuits. Then subtract the
aforesaid reading from the measured resistance.
When the meter is in open circuit, the display unit will show "OL" that
indicates the measured value is over the measuring range.
3.2.3 Diode test
To avoid the meter or the measured equipment from damage, do
not attempt a diode test unless the operator has already cut off all
power sources for the circuit to be measured and fully discharged
all high-voltage capacitors.
Diode test outside the circuit:
1. Turn the rotary switch to the position and press “FUNC/Hz” to choose
.
2. Connect the test leads in black and in red to COM input socket and V/ input
