DCA MEASUREMENT

1. Press the clamp gunlock to open the clamp jaw to get the 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 the clamp jaw. Measure one wire in a time. If more than one wire in one time, the reading will be inaccurate.
2. Turn the rotary function switch to A,c; position. The meter is defaulted at DCA measurement after power is on. Press SELECT to switch between DC measurements. 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 a Hall component to detect current. The hall component is a sensitive component. It is also sensitive. It is also sensitive to temperature and mechanical stress. Any impact on it would cause the changes in reading in a short time. This causes some remaining values on the DC ampere reading when there is no current. To get an accurate reading, press the REL key to clear the reading before measure­ment, and the testing wire must be placed in the middle of the clamp jaw.
2. Press the clamp gun lock to open the clamp jaw to get the testing wire inserted in the middle and clipped completely. Ensure that the testing wire is placed in the middle of the clamp jaw. Otherwise, there will be an 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 a 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 a long time will damage the meter.

Follow the below instructions to get a more accurate DC current measurement:

1. CDSwitch off the testing wire.
2. Press the clamp gunlock to open the clamp jaw to get the testing wire inserted in the middle and clipped completely. Ensure that the testing wire is placed in the middle of the clamp jaw.
3. When the meter reading is stabilized at the minimum value, press the REL key to clear it.
4. Switch on the testing wire. Read after the clamp meter remains stable.
5. When measuring current, to get more accurate readings, the ambient temperature must be Oto 60 “C.

ACA MEASUREMENT

1. Turn the rotary function switch to position. The meter is defaulted at DCA measurement after power is on. Press SELECT to switch between AC measurements.
2. Open the clamp jaw grip one wire and get the reading directly.

To get the most precise reading, the should user put the wire in the middle of the closed jaw.

Non-Contact Voltage Detecting
WARNING: This Function might be disturbed by different external Sources, then might incur a wrong alarm reminder, test result is just for reference when using this function. urn 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 the NCV detector as the only way to judge whether a Voltage still exists on the Wire lead or not.
2. Voltage detection may be affected by power socket design, type of insulation its thickness, and other factors.
3. interference sources at the external environment such as flashing lights, the motor might cause a wrong signal for a wrong judgment.

RESISTANCE MEASUREMENT

1. Set the rotary switch to “ ” range and press “SELECT” to swift to the “ ” range.
2. Insert the black lead into the “COM” terminal and the red one into the ‘V/ ” 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 1 O stray resistance.

DIODE AND CONTINUITY TEST
