MEASUREMENT INSTRUCTIONS
First, please check the battery, and turn the knob to the proper range
that you need. If the battery is out of power, the " " symbol will
appear on the LCD. Pay attention to the symbol next to the jack
for test leads. This is a warning that the voltage and current should not
exceed the indicated value.
1. DCV and ACV measurement
5
1-1. Set the knob to the mV/ACV/DCV range, and connect the test leads across to the circuit under test. The voltage and polarity of the point which the red test lead is connected are display on the LCD.
1-2. Insert the black test lead to "COM" jack, the red one to " " jack.
1-3.The auto range is already set by default after the meter is turned on, LCD displays "AUTO" symbol, press the "RANGE" key to convert to manual range, the range 40mV,400mV (only for DC mV/AC mV range), 4V, 40V, 400V, 1000V/750V (DCV/ACV) are optional.
1-4.You can get the result from LCD. 1-5. At the DC mV/AC mV range, short press the "Hz/DUTY SELECT"
key to convert DC/AC mV measurement. The DC mV range is already set by default after the meter is turn on. Note: (1) Do not input a voltage over DC 1000V or AC 750Votherwise the circuit might be damaged. At the DC/AC mV range, the input voltage should not exceed 250VDC/ AC RMS. (2) Please keep the test leads away from the circuit after finished your testing. (3) When measured voltage is higher than 220V, it's necessary to wear personal protective equipment (such as approved rubber gloves, face masks, and flame-retardant clothing etc.) to prevent the injury from electric shock and arc. 2. DCA and ACA measurement 2-1. Set the knob to a proper DCA/ACA range, and then connect the test leads to the power or circuit under test in series. The polarity and the current value of this point which connects to the red test lead will display on the LCD. 2-2. Insert the black test lead to "COM" jack, the red one to " " (max. 400mA) or "10A" (max. 10A) jack. 2-3. You can get the result from display.
6
2-4. Short press the "Hz/DUTY SELECT" key to convert DCA or ACA, the DCA range is already set by default after the meter is turned on. Short press "RANGE" key to convert to manual range, you can choose 400uA, 4000uA at the uA range, and 40mA, 400mA are optional at the mA range, 4A, 10A are optional at the A range. The auto range is already set by default after the meter is turned on.
Note: (1) If the tested current range is unsure beforehand, please start from
the highest range then find the proper range according to the reading. Do not measure the voltage in the current jack. (2) If the reading displays "OL"the value is beyond the present range. Now you need to set the knob to the higher range. (3) Be careful when measuring 10A range. Continuous measurement of high current will heat the circuit, even affect the accuracy and damage the meter. (4) When measuring the large current above 10A, it's necessary to wear personal protective equipment (such as approved rubber gloves, face masks, and flame-retardant clothing etc.) to prevent the injury from electric shock and arc. 3. Resistance measurement 3-1. Set the knob to resistance range, then connecting the test leads to the tested resistance. 3-2. Insert the black test lead to "COM" jack, the red one to " "jack. 3-3. You can read the measurement results from the display. 3-4. Auto range method is already set by default after the meter turned on, short press "RANGE" key to convert to the manual range, The range 400, 4K, 40K, 400K, 4M, 40M are optional. Note: (1) If "OL" displays on LCD, it means over range, now you need to set the range knob to the higher range. When measuring resistance is
7
more than 1M, the reading may take a few seconds to stabilize. This is normal for high resistance measurement. (2) When the input terminal is under open circuit, the figure "OL" will be displayed for the overload condition. (3) When checking in-circuit resistance, be sure the power has been switched off and all capacitors are fully discharged. 4. Capacitance measurement 4-1. Set the range knob to a proper capacitance range, connect the test leads to the capacitor under tested (the polarity of red test lead is "+"). 4-2. Insert the red test lead to " " jack and the black one to "COM" jack. 4-3. You can get the result from LCD. Note: (1) If the LCD displays "OL", it indicates the value is over range. The maximal range is 100mF. (2) When measuring capacitance, because of lead wire and the distributed capacitance, there may be some residual reading without connection to capacitance under measured. It will be clearer when measuring small capacitance range. Measuring result is to subtract the residual reading for getting accurate reading. This will not affect the measuring accuracy. You can short press the "REL" key to clear the residual reading of open circuit, then measuring the relative value. (3) When under a large capacitance range, if capacitor is broken or leakage, the LCD will display some value and it's unstable. (4) Discharge all the capacitance completely before measuring to avoid the damage of the meter. (5) UNIT: 1mF=1000uF 1uF =1000nF 1nF=1000pF 5. TRANSISTOR hFE 5-1. Set the knob to "hFE" range. 5-2. Insert the adapter to " " and "COM" jack, then according to
8
the NPN or PNP, insert emitter, base and collector to proper jack. 5-3. You can get the result from LCD. 6. Diode and continuity test 6-1. Set the range knob to the " " range. The diode range is already set by default after the meter is turned on, short press the "Hz/DUTY SELECT" key to convert the diode and continuity test. Set the black test lead to "COM" jack, and the red one to " "jack (the polarity of red test lead is "+"), meanwhile connect the red test lead to the positive of the diode and the black one to the negative. The reading is the approx. value of the diode positive volt drop. If the test leads connect to the reverse polarity of diode, the LCD will display "OL". 6-2. Connect the test leads to two ends of the circuit under tested, if the resistance is lower than approx.50±20, the LCD displays " " symbol, and the buzzer sounds. 7. Frequency measurement 7-1.Turn the knob to frequency range, and connect the test leads or shielded cable across the signal source or the load under tested. 7-2.Insert the black test lead to the "COM" jack and the red one to the " "jack. 7-3.You can get the result from the LCD. 7-4.Short press the "Hz/DHTY SELECT" key to convert to duty cycle. Note: (1) When it is over 10V RMS, you can get the result, but we cannot promise the accuracy. (2) It is preferable to use shielded cable for measuring small signal in noisy environment. (3) Be careful when measuring high voltage. (4) Do not input a voltage over DC 250V or AC peak value to avoid damage to the meter. (5) It is auto range at the frequency range, you can test 10Hz ~20MHz. 8. Temperature measurement
9
When measuring temperature, insert the negative of the thermocouple sensor into the "COM" jack, and insert the positive into the " " jack; put the sensing part of the temperature probe on or inside the tested object. Read the value from the LCD which shows as Celsius. Short press the "Hz/DHTY SELECT" key can convert the Celsius or Fahrenheit unit. 9. Non-contact voltage induction measurement NCV 9-1. Turn the knob to "NCV" range. 9-2. NCV induction voltage range is 48V~220V, let the upper position of the meter close to the measured electric AC power line, when the ACV is sensed, the upper red indicator lights of the meter flashing and at the same time a buzzer alarm on, the more close to the AC power line, the more stronger the ACV sensed, the corresponding flashing lights, and the buzzer alarm sounds faster. 10. Automatic power on/off To save power consumption and prolong battery life, the APO automatic shutdown function will be turned on by default after the meter is turned on. If the user does not operate the meter within 14 minutes, the meter will be prompted with 3sounds. If there is still no operation, the meter will automatically turn off the power after a long sound one minute later. Short press "SELLECT" can turn on the multimeter. To cancel APO function, please refer to the instructions in section 8, "key function".
