Operating Instructions 

WARNING

: Risk of electrocution. High-voltage circuits, both AC and DC, are extremely dangerous 

and should be measured with great care. 

1. ALWAYS turn the function switch to the 

OFF

 position when the meter is not in use. 

2. If “OL” appears in the display during a measurement, the value exceeds the range you have 

selected. Change to a higher range.  

AC/DC VOLTAGE MEASUREMENTS  

CAUTION: 

 Do not measure DC voltages if a motor on the circuit is being switched ON or OFF. 

Large voltage surges may occur that can damage the meter. 

1. Rotate the function switch to the 

V

AC

 or V

DC

 position.

 

 

2. Insert the black test lead banana plug into the negative 

COM

 jack. Insert the red 

test lead banana plug into the positive 

V

 jack. 

3. Touch the black test probe tip to the negative side of the circuit.  

Touch the red test probe tip to the positive side of the circuit. 

4. Read the voltage in the display.  

 

 

 

 

 

AC/DC CURRENT MEASUREMENTS 

1. Insert the black test lead banana plug into the negative 

COM

 jack. 

2. Press the 

MODE

 button to indicate “

DC

” or “

AC

” on the display. 

3. For current measurements up to 2000µA, set the function switch to the 

µA

 position 

and insert the red test lead banana plug into the 

µA/mA

 jack. 

4. For current measurements up to 200 mA DC, set the function switch to the 

mA

 

position and insert the red test lead banana plug into the 

µA/mA

 jack. 

5. For current measurements up to 10A DC, set the function switch to the 

10A

 position 

and insert the red test lead banana plug into the 

10A

 jack. 

6. Connect the test leads in series with the circuit under test. 
7. Apply power to the circuit. 
8. Read the current in the display.
