4.2 DCAMEASUREMENT
(1) Press the clamp gunlock to open the clamp jaw to get
testing wire inserted in the middle and clipped
completely. To ensure measurement accuracy, please
check to ensure that the testing wire is placed in the
middle of clamp jaw. Measure one wire in one time. If
measure more than one wires in one time, the reading
will be inaccurate.
(2) Turn the rotary function switch to position. The meter is default at DCAmeasurement after
power on. Press SELECT to switch between DC measurement.
(3) When the meter is used in a strong magnetic field, the readings could be unstable or inaccurate. Press
REL to clear to zero before measurement.
NOTE:
1) The meter uses Hall component to detect current. Hall component is a sensitive component. It is
magnetic sensitive. It is also sensitive to temperature and mechanical stress. Any impact on it would
cause the changes on reading in a short time. This causes some remaining values on the DC ampere
reading when there is no current. To get accurate reading, press REL key to clear reading before
measurement, and the testing wire must be placed in the middle of the clamp jaw.
2) Press the clamp gunlock to open the clamp jaw to get testing wire inserted in the middle and clipped
completely. Ensure that the testing wire is placed in the middle of clamp jaw. Otherwise there will be
additional accuracy ±1.0% of reading. Read the measurement current value of the testing wire on the
LCD.
3) In the measurement of the DC current, if the reading is positive value, the current is top to down
(broad is top, bottom cover is down).
4) The max testing current is 800A. Exceeding the rated current for long time will damage the meter.
Follow below instructions to get more accurate DC current measurement:
①Switch off the testing wire.
②Press the clamp gunlock to open the clamp jaw to get testing wire inserted in the middle and clipped
completely. Ensure that the testing wire is placed in the middle of clamp jaw.
③When the meter reading is stabilized in the minimum value, press the RELkey to clear it.
④Switch on the testing wire. Read after clamp meter remains stable.
⑤When measuring current, to get more accurate readings, the ambient temperature must be 0 to 60℃.
4.3ACA MEASUREMENT
(1) Turn the rotary function switch to position. The meter is default at DCAmeasurement after
power on. Press SELECT to switch betweenAC measurement.
(2) Open the clamp jaw and grip one wire and get the reading directly.
To get the most precise reading, should user put the wire in the middle of the close jaw.
Note:
1. Firstly users should select the highest range, if users are not sure about the range of current under
test, and then select the proper range based on displaying value.
2. DO NOT input the current higher than the limit, or it would damage the meter.
4.4ACV MEASUREMENT
(1) Set the rotary switch to “ ” range.
(2) Turn the function swift to ACV range. Insert the black test lead into “COM”
terminal, and the red one into “V/Ω” terminal.
(3) Connect the test leads into the circuit and get the measurement value from the
LCD.
Note:
1. DO NOT input a voltage over the limit or It may cause damage to the circuit of the
meter.
2. Be careful while measuring a high voltage circuit. Do not touch the high voltage
circuit.
4.5 DCV MEASUREMENT
(1) Set the rotary switch to “ ” range.
(2) Turn the function swift to DCV range. Insert the black test lead into “COM” terminal, and the red
one into “V/Ω” terminal.
(3) Connect test leads to the test point. LCD will display polarity and voltage of the test point connected
by the red test lead.
Note:
1. DO NOT input a voltage over the limit or It may cause damage to the circuit of the meter.
2. Be careful while measuring a high voltage circuit. Do not touch the high voltage circuit.
4.6 Non-Contact Voltage Detecting
WARNING
This Function might be disturbing by different external Sources, then might be incurred a wrong alarm
reminder, test result is just for reference when using this function.
Turn Switch button to “NCV” position, the Target Circuit to be placed on the top of
Meter, Meter will shows strong and weak signals, meanwhile, Beeper will makes
“tick-tick-tick” of alarm reminder.
Note:
1. Even if there is no any indication, the voltage might still be there. Do not rely on
NCV detector as the only way to judge whether a Voltage is still existed on the Wire
lead or not.
2. Voltage detecting may be affected by power socket design, type of insulation and its
thickness and other factors.
3. Interference sources at the external environment such as flashing light, motor might cause a wrong
signal for a wrong judgement.
4.7 RESISTANCE MEASUREMENT
(1) Set the rotary switch to “ ” range and press “SELECT” to swift to “Ω” range.
(2) Insert the black lest lead into “COM” terminal and the red one into “V/Ω” terminal.
(3) Connect the test leads to the measured resistance to get the measurement value.
Note:
1. Before measuring in line resistor, make sure that the power is off and all capacitors
have discharged completely.
2. Do not apply any voltage at resistance range.
3. When input terminal is in open circuit, LCD will display “OL”.
4. If there is an “OL” displayed on the LCD, it means it is over range, switch to a higher range. When
the test leads are shorted, there would be about 1Ω stray resistance.
4.8 DIODE AND CONTINUITY TEST
(1) Set the rotary switch to “ ” range. The original state is diode measurement mode.
(2) Forward measurement: Connect red test lead to the positive polarity and the black test lead to the
cathode polarity of the diode. LCD will display the approx. value of forward voltage
drop.
(3) Backward measurement: connect red test lead to the cathode polarity and the black
test lead to positive polarity of the diode. LCD will display “OL”.
(4) The complete diode testing includes forward and backward measurement. If the
result doesn’t meet the descriptions above, it means the diode is broken.
(5) Press “SELECT” key to select the continuity measurement mode.
(6) Insert the black test lead into “COM” terminal, and the red one into “V/Ω” terminal.
(7) Connect test leads to two points of tested circuit, if the resistance is less than 50 Ω, the buzzer
sounds.
Note:
DO NOT input any voltage value at this range!
4.9 CAPACITANCE TEST
(1) Set the rotary switch to “ ” range and press “SELECT” to swift to “ ” range.

(4) Connect the capacitor to “COM” and “V/Ω” terminal. (Note: the red test leads is for
positive pole +). LCD displays capacitance value.
Note:
1. Don’t input voltage or current at Capacitance range.
2. In order to assure the accuracy, please press “REL” to clear the reading before testing.
3. There is only the auto range mode under the capacitance range.
4. The capacitor must be completely discharged before testing.
5. The reading of 200uF range will take more than 15 seconds to be stable.
