3. OPERATING INSTRUCTION
3.1 MEASURING VOLTAGE
3.1.1 Connect the black test lead to the COM jack
and the red test lead to the V/jack.
3.1.2 Set the rotary switch at the desired “V” range
position and connect test leads across the source
or load under measurement.
3.1.3 Put down the "AC/DC" when measuring the
voltage. Meter will be transformed between DC
and AC range.
3.1.4 If you need data hold when measuring, you
can put on “HOLD”, it will hold the reading; if you
put the button again, data hold will not continue.
3.1.5 When only the figure“1”is displayed, it
indicates overrange situation and the higher range
has to be selected.
3.2 MEASURING CURRENT
3.2.1 Connect the black test lead to the COM jack
and the red test lead to the A jack for a maximum
of 200mA. For a maximum of 10A, move the red
lead to the 10A jack.
3.2.2 Set the rotary switch at desired “A” range
- 8 -
- 7-

position and connect test leads in series with the
load under measurement.
3.2.3 Put down the "AC/DC" when measuring the
current. Meter will be transformed between DC
and AC range.
3.2.4 If you need data hold when measuring, you
can put on “HOLD”, it will hold the reading; if you
put the button again, data hold will not continue.
3.2.5 When only the figure“1”is displayed, it
indicates overrange situation and the higher range
has to be selected.
3.3 TESTING DIODE/CONTINUITY
3.3.1 Connect the black test lead to the COM jack
and the red test lead to the V/jack. ( NOTE: The
polarity of red lead connection is positive“ ”)
3.3.2 Set the rotary switch at position and
connect the red lead to the anode, the black lead
to the cathode of the diode under testing. The
meter will show the approx. Forward voltage drop
of the diode. If the lead connection is reversed,
only figure“1”will be displayed. If continuity exists
( i.e., resistance less than about 20), built —in
buzzer will sound.

3.4 MEASURING RESISTANCE
3.4.1 Connect the black test lead to the COM jack
and the red test lead to the V/jack. ( NOTE :The
polarity of red lead connection is positive“＋”)
3.4.2 Set the rotary switch at desired range
position and connect test leads across the
resistance under measurement. Read LCD
display.
NOTE:
1. For resistance above 1M, the meter may take
a few seconds to stabilize reading.
2. When the input is not connected, i.e. at open
circuit, the figure “1”will be displayed for the
overrange condition.
3. When checking in - circuit resistance, be sure
the circuit under test has all power removed and all
capacitors are full discharged.
4. At 200Mrange display is 10 counts when test
leads are shorted. These counts have to be
subtracted from measuring results. For example,
when measuring 100Mresistance, the reading
will be 101.0 and the correct measuring result
should be 101.0 —1.0 = 100.0 M.

and the red test lead to the V/jack.
3.5.2 Set the rotary switch at the desired “BAT”
range position and connect test leads across the
battery.

condition in the above descending order before
detecting other fault conditions. The detection and
indication of the presence of a fault is handled on a
“one-per-test” basis. Once a fault is corrected, it is
recommended the cable be tested again for other
faults.
OPEN There is no “OPEN” indication. A typical
cable may have 2, 3, or 4 pairs. OPENS are
displayed as an unlit symbol. The user will
determine if a pair is present and continuous or
OPEN by comparing the illuminated symbol to the
expected number of pairs that should be good.
SHO. A short circuit condition exists (see Fig.1).
MIS. Indicates the improper assignment of
individual wire pairs to pins for the wiring schemes
tested (see Fig.2).
REV. Reverse wiring means the pin for one wire
in a pair is connected to the opposite pin for the
pair in the remote jack (see Fig.3).
SPL. Split pairs occur when the tip (positive
conductor) and ring (negative conductor) of two
twisted pairs are interchanged (see Fig.4).

3.7.1 Connect the RJ45 test jack to one end of the
cable to be tested.
3.7.2 Connect the remote unit to the other end of
the cable.
3.7.3 Push TEST button to perform test. Example:
The Cable Fault is a SHORT on Pair 1-2 and Pair
3-6, the LCD status will be as follows:
Pair 1-2, Pair 3-6, Pair 4-5, Pair 7-8, SHIE and
SHO will display at the same time.
3.7.4 Push TEST button again, Pair 1-2, Pair 3-6
and SHO will display. Continue to Push TEST
button, the next pairs will display.

5. BATTERY FUSE REPLACEMENT
If the sign“ ”appears on the LCD display, it
indicates that battery should be replaced.
Remove screws on the back cover and open
the case (see the right photo). Replace the
exhausted battery with a new one.
Fuse rarely need replacement and blow almost
always as a result of the operator’s error. Open
the case as mentioned above, and then take
the PCB out from the front cover. Replace the
blown fuse with same ratings.
- 17-

WARNING
Before attempting to open the case, be sure that
test leads have been disconnected from
measurement circuits to avoid electric shock
hazard.
For protection against fire, replace fuse only with
specified ratings: F 250mA/250V
