Voltage Measurement

1. Insert the black test lead into the negative COM terminal and the red 

test lead into the positive V terminal.

2. Set the function switch to the DCV or ACV position. 
3. Connect the test leads to the source or load being measured.
4. Read the voltage measurement on the LCD display. The polarity of the 

Red connection will be indicated when making a DC measurement.

Current Measurement

1. Insert the black test lead into the negative (COM) terminal and the red 

test lead into the positive (μA, mA) terminal for a maximum measure

-

ment of 400mA. For a maximum measurement of 10A, move the red 
test lead to the positive (A) terminal.

2. Set the function switch to the μA, mA or A position and press the DC/AC 

button to select the DCA or ACA measurement mode.

3. Connect the test leads to the source or load being measured.
4. Read the voltage measurement on the LCD display. The polarity of the 

Red connection will be indicated when making a DC measurement.
