Measurement operation

DC & AC voltage measurement

Warning: To avoid harms to you or damage to the meter from electric shock. Please do not attempt to measure voltage higher than DC/AC 1000V although readings may be obtained. The DC voltage range are 200.0mV, 2.000V, 20.00V , 200.0V and 600V and then. The AC voltage ranges are 2.000V, 20.00V, 200.0V and 600V.

To measure DC or AC voltage:

• Insert the red test lead into the “VΩ” input terminal and the black test lead into the COM terminal.
• Set the rotary switch to DC or AC range.
• Connect the test lead across with the object under testing.

The measured value will be show on the LCD display.

Note: When DC or AC voltage measurement has been completed, disconnect the connection between the testing lead and the circuit under testing.

Resistance measurement

The resistance range are: 200.0Ω, 2.000KΩ,20.00KΩ, 200.0KΩ , 2.000M Ω.20.00MΩ.

To measure resistance, connect the meter as follows:

• Insert the red test lead into the ”VΩ” terminal and the black test lead into the COM terminal.
• Set the rotary switch to proper resistance range..
• Connect the test lead across with the object under testing.

The measured value will be show on the LCD display.

Note:

• The te st lead can add 0.1 Ω to 0.2 Ω of error to resistance measurement. To obtain precision reading in low resistance measurement, that is the range of 200.0 Ω , short the input terminal before measuring. In this time, the contact resistance displayed on the LCD. Y ou can subtract the contact resistance value from the
• measured value.
• For high resistance measurement (>10M Ω ), it is normal taking several second to obtain stable reading.
• The LCD display OL indicating open circuit for the tested resistor or the resi stor value is higher than the maximum range of the meter.

Diode/Continuity check

Diode

• Set the rotary switch to   ” position. First time, default mode is diode check mode. You can enter the continuity check mode by the FUNC Key.
• insert the red test lead into the V Ω terminal and the black test lead into the COM terminal.
• Use the diode test mode to check diodes, transistors and other semiconductor device. In the diode test mode send s a current through the semiconductor junction, and the measure the voltage drop across the junction. A good silicon junction drop between 0.5V and 0.8V.
• For forward voltage drop reading on any semiconductor component,place the red test l ead on the component anode and place the black test lead on the component cathode. The measured value show on the display
• Reverse the test lead and measure the voltage across the diode again.
  • If diode is good, the display shows OL
  • If diode is shorted, the display shows 0 (zero) in both direction.
  • If display shows OL in both direction, the diode is open.

Continuity Check:

• Press the FUNC key to enter to the continuity mode.
• The buzzer sound if the resistance of a circuit under test is less than 100 Ω

Frequency measurement

• Set the rotary switch to Hz position.
• Insert the red test lead into the “ V Ω Hz input terminal and the black test lead into the COM terminal.
• Connect the test leads across with the circuit under test ing . The measured value shown.on the LCD display.

NOTE: Input signal level must be higher than 0. 5V (it is sensitivit y).

DC/AC µ A or mA measurement

DC Current range is 200.0 µ A/2000 µ A and 20.00mA,/200.0mA and then 10A range.

AC Current range is 200.0 µ A/2000 µ A and 20.00mA,/200.0mA and then 10A range.

• Turn off power to the circuit. Set the rotary switch to the properDC/AC µ A or DC/AC mA position.
• Break the current path to be tested. Connect the red test lead to the more positive side of the break and the black test lead to the more negative side of the break.
• Turn on power to the circuit. The measured value show on the display.

DC/AC 1 0A measurement

• Insert the red test lead into the input terminal marked as “10A”.
• The measuring procedure is same as that of 5 5 section.

Note:

• For safety s sake, the measuring time for high current should be 10 second for each measurement and the interval time between two measurement should be greater than 5 minutes.
• When current measurement has been completed, disconnect the connection between the testing lead and the circuit under test.

Capacitance measurement

Note: To avoid damage to the instrument or device under test to measure capacitance previously, should cut off all power of the circuit to be measured and all high voltage capacitors discharge. DC voltage function determines the capacitor has been discharged.

• Capacitance is component’s ability to store charge.
• The unit of capacitance is ferrari (F). Most of the value of the capac itor is in thelaw (nF) between micro method (F). Instrument is through the capacitor charging (with a known current and time), then measure the voltage, then calculate capacitance value. 1000 mu F measuring takes about eight seconds, the faster the smaller capacitance measurement. Instrument test more than 500 mu F, there will be a slight jumps phenomenon.

Measurement of capacitance

• The rotary switch to gear.
• Respectively connects black test pens and a red pen to COM input socket and input socket.
• Use the test pen on both ends of the other measuring capacitance of the capacitor under test value and measured value read from the LCD display.
• When the meter measuring large capacitance, it takes time to stable reading.

Maintenance

• Replacing t he battery

When meter display the battery must be replace to maintain normal operation.

• Disconnect and remove all test probes from any live source and meter.
• Open the battery cover on the bottom case by screwdriver.
• Remove old batt ery and snap new one into battery holder

Fuse replacement

Replacing the defective fuse should the done according to the following procedure.

• To avoid electrical shock, remove the test lead and any input signal before opening the bottom case.
• Open the botton case and then remove the defective fuse and insert a new fuse of the same size and rating.
• Replace the bottom case and reinstall all the screw.

Cleaning and Decontamination

• The meter can be cleaned with soft clean cloth to remove any oil, grease or grim. Do not use liquid solvent or detergent.

Caution Please turn off the item when it is not in use in order to prolong its work ing l ife.
