WARNING

To avoid possible electric shock or personal injury, and to avoid damaging the multimeter or equipment being tested, adhere to the following rules:

• Before using the meter, inspect the exterior casing. Do not use the meter if it is damaged or if any part of the exterior casing is removed. Look for cracks or missing plastic. Pay special attention to the insulation around its connectors.
• Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity.
• Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and grounding.
• The manual rotary switch should be placed in the correct position before any measurements and should NOT be moved during measurements to prevent damage to the meter.
• When the meter is working at an effective voltage over 60 Vin DC or 30 V rms in AC, special care should be taken because there is an increased danger of electric shock.
• Use the appropriate terminals, functionss and range for your measurements.
• Do not use or store the meter in a high-temperature environment, do not exposeit to high levels of humidity,or use it near strong magnetic fields. The performance of the meter may deteriorate after being exposed to any of these environments.
• Disconnect the circuit’s power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or hFE.
• When using the test leads, keep your fingers behind the finger guards.
• Replace the battery as soon as the battery indicator appears. With a low battery, the meter may produce inaccurate readings that can lead to electric shock and personal injury.
• Remove the connection between the testing leads and the circuit being tested, and power off the meter before opening its case.
• When servicing the meter, only use replacement parts with an identical model number or electrical specifications.
• Do not alter the meter’s internal circuit. Doing so may damage the meter.
• Only clean the surface of the meter using a soft cloth and mild soap. Do not use abrasive materials or harsh chemicals; doing so may corrode and damage the meter.
• Turn the meter off when not in use and take out the battery when it is not going to be used for an extended period of time. Regularly check the battery as it may leak when it has not been used for some time. Replace the battery as soon as leakage appears. A leaking battery will damage the meter.

1. Connect the test leads: Insert the red test lead into the “Input” jack and the black test lead into the “COM” jack.
2. Turn the rotary switch to the “v-” or “v~ “setting according to the measured voltage.
3. Connect the circuit: Connect one end of the test leads to the circuit that needs to be measured, in parallel with the circuit.
4. Reading: record the reading from the LCD screen.
5. After measuring, turn the rotary switch to the OFF position to turn off the meter.

NOTE:

• When a small measuring range is selected, the display of the multimeter may show unstable results if the test leads are not connected to the load. This is a normal event and will not affect the measurements.
• During DC voltage measurements, use the ” – ” symbol on the screen to judge the polarity of the red test lead connection. Without the ” – ” symbol onscreen, the red test lead is connected with positive polarity.
• To avoid damaging the meter, do not measure voltages exceeding 600V DC or 600VAC.
• If necessary, the “Range” Button can be pressed to manually set the range (default mode is auto range). During manual operation, please choose the widest range by pressing the “Range” Button, then choose an appropriate range based on the initial readings. When the “OL.:’ symbol is displayed on the screen, users must choose a wider range to obtain a reading. In Auto Range Mode, a range does not need to be manually set.
• Do not use the AC voltage test function to test DC voltage and vice versa. Performing this action has the potential to damage the meter or any components you are attempting to test.

Current Measurement

1. If the current to be measured is less than 600 mA, insert the red test lead into the “μA” “mA” jack. If the current is between 600 mA and 10 A, insert the red test lead into the “10 A” jack instead. 
2. Choose functions: Turn the rotary switch to the “μA”, “mA”, or “A” setting according to the estimated value.
3. Choose current types: Press the “Select” Button to choose between a DC or AC test.
4. Connect the circuit: Connect the test lead to the source lead or load to be measured in series with the circuit.
5. Reading: record the reading from the LCD screen.
6. After measurement, turn the rotary switch to the OFF position to turn off the meter.

NOTE:

• DO NOT test currents exceeding 10 A AC/DC.
• When performing DC measurements, determine the polarity of the red lead connection based on the presence or absence of ” – ” on the display.
• For your safety when testing a high current, each measurement time should be less than 10 seconds, and the interval time between tests should be greater than 15 minutes.
• When testing the current, there must be a load in the circuit. Do not connect the multimeter in series with the circuit without a load to measure; doing so may damage the meter.
• If necessary, the “Range” Button can be pressed to operate manually (default mode is auto range). During manual operation, please choose the widest range by pressing the “Range” Button, then set an appropriate range based on the initial reading access to precise reading. When the “QL:’ symbol is displayed on the screen, set a wider range to get results. In Auto Range Mode, a range does not need to be manually set.

Current Measurement (with Clamp Attachment)

1. Connect the leadsUsese clamps to test AC. Insert the black test lead into the “COM” jack. If the current is less than 600 mA, insert the red test lead into the “μ/1:’ “m/1:’ Jack. If the current ranges from 600 mA to 10 A, please insert the red test lead into the “10/1:” jack.
2. Choose functions: Turn the rotary switch to the  setting.
3. Then, clamp the circuit to be tested and slowly release the trigger until the clamp head is completely closed. Ensure the circuit to be tested is in the center of the clamp head.

5. After completing your measurement, turn the rotary switch to the OFF position to turn off the meter.

NOTE:

• Each time a measurement is taken, ensure only one cable is clamped and is in the center of the clamp jaws.
• The clamp can only test up to 600 ADo not test circuits higher than 600 A.
• Do not touch the circuit with your hand or skin.
• The multimeter assumes a clamp has a sensitivity of 1 A/1 mV. The indicated value is the same as the measured value for clamps with 1 A/1 mV.
• If you use a clamp with a sensitivity that does not equal 1 mV/1 A, multiply the present reading by a factor that is determined by the used clamp; the result is the measured value. To determine this factor, please refer to the instruction manual of the other clamp.

Resistance Measurement

1. Connect: Insert the black test lead into the “COM” jack and the red test lead into the “INPUT’ jack.
2. Choose functions: Turn the rotary switch to the “” setting, the “MO” symbol will display on the screen. 
3. Connect the load: Place the test leads at both ends of the load to be measured.
4. Reading: record the reading from the LCD screen.
5. After measurement, turn the rotary switch to the OFF position to turn off the meter.

NOTE:

• If the resistance test value exceeds 1 MO, the meter may take a few seconds to stabilize the reading, which is normal for high resistance testing.
• Do not change the resistance while taking measurements. Doing so may damage the meter and affect the test results.
• Do not test parallel circuits. The accuracy of the measurement will be affected, and the results may not be accurate.
• Do not directly measure the internal resistance of micrometers, galvanometers, batteries,and other such instruments.
• In case of disconnection, the symbol “DL.:’ will be displayed.
• Before testing the internal resistance of the circuit, please ensure that all power sources are removed from the tested circuit and all capacitors are fully discharged.
• If necessary, the “Range” Button can be pressed to operate manually (default mode is auto range). During manuaoperationti  on please choose the widest range by pressing the “Range” Button, then set an appropriate range based on the initial reading access to precise reading. When the ·ot.:· symbol is displayed on the screen, set a wider range to get results. In Auto Range Mode, a range does not need to be manually set.

3. Connect the diode: Connect the red test lead to the positive end of the diode and the black test lead to the negative end.
4. Reading: The meter will display the approximate value of positive voltage. If the leads are incorrectly connected to the diode electrodes, the LCD will display “O.. To fix this change the tetest leads’  position.
5. After measurement, turn the rotary switch to the OFF position to turn off the meter.

NOTE:

• Is the diode functioning correctly? If the red test lead is connected to the positive pole of the diode and the black lead is connected thethe negative, then the diode should be in a forward conduction state, and the displayed value is the forward voltage drop.
• Normal diode forward pressure drop: the general silicon tube is 0.5-0.7 V, the germanium tube is 0.15-0.3 V.
• Polarity Judgment Method:
  1. Switch the multimeter to the Resistance setting.
  2. Connect the two test leads to the two electrodes of the diode.
  3. Measure one result, then swap the positions of the test leads, then measure the second result.
  4. The larger result is the reverse resistance, and the smaller result is the forward resistance. The smaller resistance is when the black test lead is connected to the positive end of the diode and the red lead is connected to the negative end.
