Operation 

NOTICES

: Read and understand all 

warning

 and 

precaution

 statements listed in the 

safety section of this operation manual prior to using this meter. Set the function 

select switch to the OFF position when the meter is not in use. 

AC/DC Current Measurements

WARNING: 

Ensure that the test leads are

disconnected from the meter before making current  

clamp measurements. 

1. 

Set 

the 

Function 

switch 

to        

the

400ADC,40ADC,400AAC or40AAC

 range. 

2.  If the range of the measured is not known,  

select the higher range first then move to the lower  

range if necessary. 

3. Press the trigger to open jaw. Fully enclose one conductor 

 to be measured.

The clamp meter LCD will display the reading.

AC/DC Voltage Measurements  

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 

V

 position. 

3.  Select AC or DC with the 

MODE

 button.  

4.  Connect the test leads in parallel to the circuit under test. 
5.

Read the voltage measurement on the LCD display.  

Resistance Measurements 

1. 

Insert the black test lead into the negative 

COM

 terminal and the 

 red test lead into the positive terminal. 

2. 

Set the function switch to the   

:

•))) CAP

 position.                                                              

3. 

Touch the test probe tips across the circuit or component under  
test. It is best to disconnect one side of the device under test so  
the rest of the circuit will not interfere with the resistance reading. 

4. 

For Resistance tests, read the resistance on the LCD display. 

Diode and Continuity Measurements

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

COM

 jack and the red test lead 

banana plug into the positive diode jack. 

2.  Turn the rotary switch to the 

:

•)))

 CAP position. 

3.  Press the 

MODE

button until “     “ appears in the display.

4.  Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to 0.7V. 

Reverse voltage will indicate “

OL

”. Shorted devices will indicate near 0mV and an open 

device will indicate “

OL

” in both polarities.
