The polarity of the red lead connection will be indicated along with the current value
when making DC current measurement.
3. When only the figure”1” displayed, it indicates overrange situation and the higher
range has to be selected.
3.3 MEASURING FREQUECY
1. Connect the black test lead to the COM jack and the red test lead to the V
Ω
Hz
jack.
2. Set the rotary switch at kHz position and connect test leads across the source or
load under measurement.
NOTE:
1. Reading is possible at input voltages above 10Vrms, but the accuracy is
guaranteed.
2. ln noisy environment, it is preferable to use shield cable for measuring small
signal.

3.4 MEASURING RESISTANGE
1. Connect the black test lead to the COM jack and the read to the V
Ω
Hz jack.
(The polarity of red lead is
〝
+
〞
)
2. Set the rotary switch at desired
Ω
position and connect test leads across the
resistor under measurement.
NOTE:
1. If the resistance being measured exceeds the maximum value of the range
selected or the input is not connected, an overrange indication
〝
1
〞
will be
displayed.
2. When checking in – circuit resistance, be sure the circuit under test has all power
removed and that all capacitors have been discharged fully.
3. For measuring resistance above 1M
Ω
, the meter may take a few seconds to get
stable reading. This is normal for high resistance measurements.
4. At 200M
Ω
range display reading is around 10 counts when test leads are
shorted.

These counts have to be subtracted from measuring results. For example, when
measuring 100M
Ω
resistance the display reading will be 101.0 and the correct
measuring result should be 101.0-1.0=100.0M
Ω
.
3.5 MEASURING CAPACITANCE
1. Set the rotary switch at desired F position.
2. Before inserting capacitor under measurement into capacitance testing socket, b
e
sure that the capacitor has been discharged fully.
3. When measuring capacitors with shorter leads, a testing adapter is provided with
the meter. Insert the adapter into the capacitance testing socket on the front panel
to continue measurements.
WARNING
To avoid electric shook, be sure the capacitor measuring adapter has been
removed before changing to another function measurement.
