4.4.6. Capacitance 

measurement 

 

 

CAUTION 

 

Before carrying out capacitance measurements on circuits or capacitors, cut 
off power supply from the circuit being tested and let all capacitance in it be 
discharged. When connecting the multimeter and the capacitance to be 
measured, respect the correct polarity (when required). 

 

 

Fig. 27: Use of the instrument for Capacitance measurement 

1. Select 

position 

CAP

 

2. Press 

the 

F2 (MODE) key until the symbol 

“

nF

” 

is displayed. 

3.  Insert the red cable into input terminal VHz%CAPTemp 

 and the black cable 

into input terminal COM. 

4. Press 

the 

REL/

 key before carrying out measurements. 

5.  Position the leads at the ends of the capacitor to be tested, respecting, if necessary, 

the positive (red cable) and negative (black cable) polarity (see Fig. 27). The display 
shows the value of capacitance. The bargraph is not active in this function. 

6. The 

message 

“

O.L.

” 

indicates that the value of capacitance exceeds the maximum 

measurable value. 

7.  To use the HOLD and REL function, see § 4.2.   
8.  To use the internal functions, see § 4.3.
