4.3.2.  DC Voltage measurement 

 

 

CAUTION 

 

Maximum input for DC Voltage measurements is 1000V. Do not take any 
voltage measurement exceeding this limit in order not to risk electrical 
shock or damaging the tester. 

 

 

Fig. 4: Taking DC voltage measurements 

 

1.  Rotate the switch on   position 
2.  Insert the red test lead plug into 

V

 

CAP Temp

 jack and the black test lead plug 

into 

COM

 jack (Fig. 4) 

3.  Connect the two long ends of test leads to the desired circuit, then reading will be 

displayed 

4. When “

O.L.

" symbol is displayed, the result is over the maximum value that the 

instrument is able to measure 

5.  For HOLD, MAX/MIN and REL features please refer to § 4.2 

 

 

CAUTION 

 

  Due to the high input impedance is possible that the meter performs the 

zero of the display taking longer 

  The possible blinking values shown at display with open input terminals 

are not a problem of the meter

 and these values will not be added to 

the measured value
