5.4.3 Basic Current Measurements 
WARNING Do not measure the current on a circuit when the voltage increases to 
more than 1000V. This can cause damage to the instrument and can cause injury to 
persons. 
 
When measuring current using the clamp jaws, only one conductor should be enclosed 
by the jaws—refer to Figure 5.2. 
 
 
 
Figure 5.2 Correct and incorrect setup 
 
1.  Ensure that the probe leads are disconnected from the meter. 
2.  Set the function switch to the A position. 
3.  To manually select AC or DC use the MODE button. 
4.  To manually select the measurement range (scale), press the RANGE button 
repeatedly. Refer to section 5.3 Auto/Manual range mode. 
5.  Press the trigger to open the clamp jaws. Fully enclose one conductor—refer to 
Figure 5.2. For optimum results, center the conductor in the jaws. 
6.  Read the current value on the display.
