Description of Measurement Operation

AC / DC Voltage Measurement

1. Set the rotary switch to the voltage position. (V / V~)
2. If required press the select button to change the voltage sine wave from DC V to AC (V~)
3. Insert the black test lead banana plug into the negative COM input terminal & insert the red test lead banana plug into the positive V/ΩmA input terminal.
4. Connect test leads to the conductors to be tested.
5. Read the voltage in the LCD display.
   PLEASE NOTE: That the polarity of red test lead must be connected to the positive conductor to indicate the positive voltage measurement when conducting DC voltage measurements.

AC/DC Current Measurement

1. Select the rotary switch to the appropriate current measurement function & range.
2. Insert black test lead banana plug into the negative COM input terminal.
3. To perform current measurements less than 200mA insert the red test lead banana plug into the mA Input terminal or for current measurements between 200mA to 10A insert the red test lead banana plug into the 10A input terminal
4. Disconnect the circuit under test then connect the test leads in series with the circuit.
5. Turn the power on and read the measurement value displayed.
   If OL (Over Limit) is displayed, increase the measurement range/function.

Diode Test

1. Set the rotary switch to the “ ” position.
2. Connect the black test lead to the “COM” terminal and the red test lead to the “VΩ:” input terminal.
3. Pres the “SEL” button to select the diode function (If required)
4. Connect the test leads to the diode, test both the “Forward Bias & Reverse Bias” of the diode under test. Open circuit measurements will be indicated as OL on the display,

Continuity Indication / Buzzer Test

1. Set the rotary switch to the “ ” position.
2. Connect the black test lead to the “COM” terminal and the red test lead to the “VΩ:” input terminal.
3. Pres the “SEL” button to select the continuity function (If required)
4. Connect test leads to the circuit under test.
5. Measurement will be displayed and the audible indicator will sound, when measurements are under 70Ω.

Resistance Measurement

1. Set the rotary switch to the required resistance range.
2. Insert the black test lead banana plug into the negative COM input terminal & insert the red test lead banana plug into the positive V/ΩmA input terminal.
3. Connect test leads / probes to the measuring points
4. Read resistance measurement displayed on the LCD.
   If OL (Over Limit) is displayed, increase the measurement range/function.

Temperature Measurement

1. Set rotary switch to the “°C°F” function.
2. Select the measurement type by press the “SEL” button.
3. Connect the thermocouple by inserting the black lead in to the COM input terminal & insert the red lead in to the V/ΩmA input terminal.
4. Place the thermocouple either on or in the vicinity of the object / room under test.
5. Wait while measurement stabilizes.
6. Read temperature measurement displayed on the LCD.
