11.9 Testing in Accordance with DIN VDE 0751

The following measurements can be performed in accordance with the 
above mentioned standard:

•

Protective conductor measurement R

PE

, test current: 200 mA DC

•

Insulation measurement R

ISO

 (can be additionally activated)

– R-ISO LN-PE

(Insulation resistance LN to protective conductor)

•

Equivalent device leakage current I

EDL

•

Device leakage current (direct measurement or by means of differential 
current)

•

Patient leakage current with probe

(Patient leakage current is not possible with SFC „Mains at Application Part“)

•

Equivalent patient leakage current with probe

Leakage current is converted to reference voltage (see limit values, 
chapter 8 on page 15). 
Reference voltage must be matched to the supply voltage range.

Check connection parameters and start test.

To 
Socket

This is the default setting. Refer to chapter 7 on page 14 for 
other types of connection.

Class

If the test instrument is equipped with features B00, 01 or 03, 
and if the DUT has been connected to the test socket, safety 
class recognition is performed (SC I or SC II). 
In all other cases, or if it is not clear whether or not all 
exposed, conductive parts are connected to one another or 
to the protective conductor, the safety class can be selected 
manually.

Type

Select the type of device under test from a list (device type).
If “Old devices” is selected, limit values specified in 
DIN VDE 0702 are used.

Ap. parts... (BF): The type of application parts can be changed manually: 

Select the “Ap. Parts” line with the 

 

or 

 key, acknowledge 

with the 

 

key and change with the 

 

or 

 

key

.

ID No.

See parameters database in chapter 11.2 on page 27.

Refer to chapter 11.2 on page 27 regarding setup of the 
measuring sequence.
