4．Phase Measurement
Phase Test relationship of the instrument: U1U2, I1I2, U1I2,
I1U2, for every relationship the measured phase shows signal
1 ahead of signal 2.
The red U1 and U2 voltage jacks and the red dot marks or
arrow symbols on the clamp are dotted terminals
In phase test the direction of the input current should be in line
with the arrow symbol on the clamp
The phase relationship of three-phase line could be tested in
doubles.
（1）U1U2 Phase Test
Point the rotary switch to U1U2, connect the 4 black and red test lines with the
voltage input jacks of U1 and U2, and then connect the test lines with the U1 and U2
circuits; the result indicates the phase between the two circuits, namely the phase
angle between U1 and U2.
In U1U2 phase test, the two input circuits are fully isolated by insulation to avoid
short-circuit burning off caused by incorrect wiring.
（2）I1I2 Phase Test
Point the rotary switch to I1I2, connect the 2 current clamps to the current input
jacks of I1 and I2, and then connect the clamps with the I1 and I2 circuits; the result
indicates the phase between the two currents.
（3）U1I2 Phase Test
Point the rotary switch to U1I2, connect the 2 black and red test lines with the
voltage input jack of U1 and the current clamp with the current input jack of I2 in front;
then connect the test lines with the U1 and I2 circuits; the result indicates the phase
between the voltage and current.
（4）I1U2 Phase Test
Point the rotary switch to I1U2, connect the current clamp with the current input

- 8-
jack of I1 in front and the 2 black and red test lines with the voltage input jack of U2,
and then connect the clamp and test line with the I1 and U2 circuits; the result
indicates the phase between the current and voltage.
5．AC Current, Leakage Current Measurement
Point the rotary switch to the 10A range of I1, connect 1 current clamp to the input
I1 current jack in front, and then connect the current clamp with the measured circuit; the
result indicates the current or leakage current of the measured circuit. If the measured
current is relatively lower, just choose lower range and try again, so as to improving the
accuracy. Or point the rotary switch to the appropriate range of I2 and test the current or
leakage current with I2.Please note that the I1 and I2 pointed to by the switch must
correspond to the I1 and I2 input jacks on the clamp.
6．AC Voltage Measurement
Point the rotary switch to the 500V range of U1, connect 2 black and red test lines with
the U1 voltage input jack, and then connect the test line with the measured circuit; the
result indicates the current or leakage current of the measured circuit. If the measured
voltage is relatively lower, just choose lower range and try again, so as to improving the
accuracy. Or point the rotary switch to the appropriate range of U2 and test the voltage
with U2.Please note that the U1 and U2 pointed to by the switch must correspond to the
U1 and U2 input voltage jacks.
7．Inductive, Capacitive Circuit Judgment
Point the rotary switch to U112, input the circuit voltage into the U1 jack and the circuit
current into the I2 jack, if the phase is displayed as between 0° and 90°, the measured
load is inductive, if the phase is displayed as between 270° and 360°, the measured load
is capacitive.
8．Three-phase Voltage Phase Sequence Measurement
（1）Phase Sequence Discrimination of Three-phase Three-wire System
Point the rotary switch to U1U2, use test lines to connect the Aphase with the red
U1 jack, the Bphase with the black U1 and U2 jacks, and the Cphase with the red U2
jack. If the measured phase value of is 300°, it’s a positive phase sequence; if the
measured phase is 60°,it’s a negative phase sequence.

(2)Phase Sequence Discrimination of Three-phase Four-wire System
Point the rotary switch to U1U2, use test lines to connect the Aphase with the red
U1 jack, the Bphase with the red U2 jack, and the null line with the black U1 and U2
jacks. If the measured phase value of is around 120°, it’s a positive phase sequence; if
the measured phase is 240°,it’s a negative phase sequence.
F．Battery Replacement
Take note of the battery polarity, the polarity must be properly
installed, otherwise it causes damage to the instruments
Batteries replacement is prohibited in hazardous area
Must use qualified alkaline batteries（1.5V AA×6）
Old and new batteries are not allowed to mix in use.
1．“ ”is displayed when the power voltage is lower than 7.8V～8V,indicating that the
battery should be replaced as following.
2．Press OFF to switch off
3．Use the cross screwdriver to loose a screw on the battery cover, open the battery cover.
4．Remove the old batteries and replace a new battery, please take note of the battery
polarity.
5．Cover the battery cover, tighten the screws.
6．Press ON to switch on to check whether the battery is successfully replaced, repeat step
2 if it doesn’t work.
7．Take out the batteries if the instrument will not be used for a long time.

G．Other Descriptions and Notes
1．The special utility of current clamp
The two current clamps of each meter could only be used on this instrument.
The current clamp should be prevented from any impact, the clamp surface must be
kept clean and could fully close for a reliable test.
2. The maintenance of current clamp
The dust on the surface of the current clamp should be removed promptly after use;
don’t use rough material or corrosive to clean the clamp, which is best to be gently wiped
clean with soft cloth and lubricants (for example: WD-40 lubricants).
3. Preheat 3 to 5 minutes before the measurement to ensure the measurement accuracy
4．The instrument should be used for secondary and low-voltage circuit detection, and
cannot be used to measure the current of high-voltage lines to prevent electric shock.
