USE

Measuring DC or AC voltage

1. Connect the black test lead to the “COM” terminal and the red test lead to the “VΩmA” terminal.

2. Set the range selector to the desired V.DC or V.AC range position.
   If the amplitude of the voltage to be measured is unknown, set the range selector to the highest range and reduce range by range until satisfactory resolution is achieved.

3. Connect the test leads to the source or circuit to be tested.

4. View the measurement on the display. For DC voltage measurements, the polarity of the red test lead connection will also be shown.

Note:
To avoid damage or injury, please do not measure voltage above 500V dc/ac even if you get a reading.
Measuring direct current

1. Connect the black test lead to the “COM” terminal. Connect the red test lead to the “VΩmA” terminal if the current to be measured is less than 200mA. If the current is between 200mA and 5A, connect the red test lead to the “5A” terminal.
2. Set the range selector to the desired A.Continue range position.
3. Turn off the power to the circuit under test. Then discharge all high voltage capacitors.
4. Turn off the test circuit and connect the test leads in series to the circuit.
5. Turn the circuit back on and see the measurement on the display.

The polarity of the red test lead connection will also be shown.
Note: If the magnitude of the current to be measured is unknown, set the range selector to the highest range and reduce range by range until satisfactory resolution is achieved.
Measuring Resistance

1. Connect the black test lead to the “COM” terminal and the red test lead to the “VΩmA” terminal.
2. Set the range selector to the desired Ω range.
3. Connect the test leads to the test object.
4. View the reading on the display.

Note:

1. For measurements > 1MΩ, the multimeter needs a few seconds to stabilize the measurement reading. This is a normal procedure for high resistance measurements.
2. When the input is not connected, for example on an open circuit, only the number 1 is shown on the display.
3. Before testing, please disconnect the circuit to be tested from any power supply and fully discharge any capacitors.

Testing the diode

1. Connect the black test lead to the “COM” terminal and the red test lead to the “VΩmA” terminal. (Note: The polarity of the red cable is positive “+”.)
2. Set the range selector switch to the position .
3. Connect the red test lead to the anode of the diode under test and the black test lead to the cathode of the diode.
4. The display shows the approximate forward voltage drop of the diode. If the connection is reversed, only the number 1 is shown on the display.

Note:
Before testing, please disconnect the circuit to be tested from any power supply and fully discharge any capacitors.
Measuring the gain of a transistor
Unlike a diode, the transistor has 3 connections. There are 2 types of transistor “NPN” or “PNP” which have the same operating principle.
The current Ie at the output of the emitter = current Ib (base input) + current Ic (collector input).
The ratio between lc and Ib is called the transistor gain.

• Set the selector switch to the hFE position.

• Insert the emitter (E), base (B), collector (C) of the transistor to be tested into the appropriate inputs (one side for a transistor).
  inputs (one side for a PNP transistor and the other for an NPN transistor).

• Read the hFE value (current gain) of the transistor.

| Test current lb| 10 pA
---|---|---
VCE = test voltage between collector-transmitter| Test voltage VCE| 2.8 V
Gain| | 0 to 1000

NOTE: If you do not know the type of transistor, choose either NPN or PNP. If the display shows (negative) the choice is wrong, or the transistor is defective.
