Auto  Select

In the 

Auto Select

 switch position, the auto-select function 

(automatic selection of measuring function) allows for 
autonomous recognition of the measured quantity, which is 
applied between earth and the voltage jacks.
An overview of possible measured quantities as well as the 
respective prerequisites for recognition can be found in the 
AUTO SELECT table on page 67.

Note!

☞

Diodes must be connected from the anode side (“+” 
pole) to the 

 jack. 

For polarized capacitors, the “+” pole must be con-
nected to the “F” jack and the “–” pole to the 

“

⊥

” 

jack.

Resistors and semiconductor paths connected in 
parallel to the capacitor distort measurement 
results!

➭

Set the rotary switch to AUTO SELECT.

Attention!

!

In the auto-select function, 

no more than 600 V

TRMS

 

may be applied between “

⊥

” and “V” jacks.

➭

Connect the measurement cables as shown. The “

⊥

” 

jack should be grounded.

Note!

The following chapter contains more information 
concerning individual measured quantities.
