Accessories (not included)
Z751A Barcode Reader
For connection to the USB master port 
at the test instrument, and for reading 
in barcodes. This makes it possible to 
conveniently insert the ID numbers of 
DUTs into single measurements and 
test sequences. 
This device is based upon the concept 
of an instinctive scanning distance and 
provides best possible reading perfor-
mance. Green Spot technology pro-
vides a “good-read” projection directly 
on the code. The device is equipped 
with a USB port.
Barcode printer Z721E
For connection to the USB 
master port at the test 
instrument, and for printing 
out barcode labels.

Z721S Thermal Printer 
For connection to the USB 
master port at the test 
instrument, and for printing 
out test reports. 
SCANBASE RFID (Z751E) 
(RFID read / write) 
Compact write/read device 
with USB interface for pro-
gramming and reading of 
13.56 MHz transponders 
per ISO 15693.
SECUTEST BASE10/PRO/SEC-
ULIFE ST BASE(25) enable 
the user to populate the 
RFID tags direcly from the 
test instrument with the 
help of the programmer.
CEE Adapter (Z745A) for Testing Single and 3-Phase Electrical Devices
The Z745A CEE adapter allows for quick and efficient testing of 
devices equipped with a CEE plug. The adapter is equipped with 
the following CEE flush-type socket outlets: 5-pole 16 A, 5-pole 
32 A and 3-pole 16 A. Furthermore, the adapter includes five 
4 mm safety sockets to which 3-phase devices without perma-
nently attached plug or conventional measurement cables can be 
connected, e.g. by means of quick clamp terminals (not included).
The following tests can be performed on devices with CEE plugs 
with the help of the adapter:
• Testing of protective conductor continuity
• Insulation resistance, alternatively leakage current (equivalent 
leakage current)
• Function test (3-pole CEE outlet only)
The Z745A CEE adapter may also be used as an adapter for con-
necting devices with 3-pole CEE plugs to common earthing con-
tact outlets.
VL2 E (Z745W) 
Test adapter with 
single-phase and 
3-phase plug con-
nectors up to 
CEE 32A 
AT16-DI (Z750A) 3-Phase 16 A Differential Current Adapter
Devices which are 
equipped with a 5-
pole, 16 A / 6 h 
CEE plug can be 
quickly and effi-
ciently tested with 
the AT16-DI CEE 
adapter.
The following tests 
can be performed 
on devices with 
CEE plugs with the 
help of the AT16-DI 
CEE adapter:
•Testing of 
protective conductor continuity
• Insulation resistance, alternatively leakage current (equivalent 
leakage current)
• Measurement of protective conductor resistance with the following 
methods: equivalent leakage current / differential current / direct
• Function test
This differential current adapter is also available in a variant with a 
5-pole 32 A / 6 h CEE plug with the designation AT32-DI CEE adapter.
