OPERATING INSTRUCTIONS 

Current Measurements using the Clamp, DC/AC 

WARNING: 

 Make sure that the test leads are disconnected from the meter’s terminals before 

making current measurements with the clamp jaw. 

WARNING: 

 For safety, use the rubber input terminal cover when measuring current using the 

Clamp. 

1. 

Set the Function switch to 

2000A

 position. 

2. Press 

the 

FUNC

 key to select AC or DC current 

3. 

For DC current measurements, push & hold 
the 

DCA ZERO

 button until the reading 

indicates zero. 

4. 

Press the trigger to open jaw. Fully enclose 
the conductor to be measured (see 
diagram). 

5. 

The clamp meter will automatically select 
the proper range (Auto Range). To select 
the range manually, press the 

RANGE

 

button before pressing 

DCA ZERO

 button. 

6. 

Read the measured value from the LCD 
display. 

 

NOTE

: If the 

DCA

 zero button is used to zero the 

meter, the clamp meter remains in the auto-range mode. If the 

REL

 button is used, the 

clamp meter will be placed in the manual range mode. 

 

Current Measurements using the Test Leads, DC/AC  

1. 

Set the Function switch to the 

mA

 or 

µA

 position. 

2. Press 

the 

FUNC

 key to select AC or DC. 

3. 

Connect the black test lead to the 

COM

 terminal and the red test 

lead to the 

mA µA

 input jack. 

4. 

Break the circuit under test (put the meter in series with circuit 
under test) refer to diagram. 

5. 

Read the measured value from the LCD display. 

NOTE:

 The maximum reading for direct input current is 240mA AC/DC. 

INCORRECT

More than one

conductor in jaws

CORRECT

One conductor in jaws

µA and mA

Current
