Display with Selectable Language
The LCD panel consists of a backlit dot matrix at which menus, 
setting options, measurement results, tables, instructions and 
error messages, as well schematic diagrams appear.
The display can be set to the desired language depending on the 
country in which the test instrument is used: 
D, GB, I, F, E, P, NL, S, N, FIN, CZ or PL
Operation
Device functions are selected directly with the help of a rotary 
selector knob. Softkeys allow for convenient selection of sub-
functions and parameter settings. Unavailable functions and 
parameters are automatically prevented from appearing at the 
display. 
The start and RCD tripping functions included directly on the 
instrument are identical to the functions of the two keys located 
on the test plug, allowing for easy measurement at difficult to 
access locations. 
Schematic diagrams, measuring ranges and help texts cab be 
displayed for all basic functions and sub-functions.
Phase Tester
Protective conductor potential is tested after starting a test 
sequence and touching the contact surface for finger contact. 
The PE symbol appears at the display if a potential difference of 
more than 25 V is detected between the contact surface and the 
protective contact at the mains plug.
Error Indication
• The instrument automatically detects instrument-to-system con-
nection errors, which are indicated in a connection pictograph.
• Errors within the electrical system (no mains or phase voltage, 
tripped RCD) are indicated at 3 LEDs and by means of pop-
up windows at the tilting LCD panel.
Battery Monitoring and Self-Test
Battery monitoring is conducted while the instrument is subjected 
to an electrical load. Results are displayed both numerically and 
with a symbol. Test images can be called up one after the other, 
and LEDs can be tested during the self-test. The instrument is 
shut down automatically when the rechargeable batteries are dis-
charged. A microprocessor controlled charging circuit is used to 
assure safe charging of rechargeable NiMH or NiCd batteries.
Data Entry at the RS 232 Port
Data can be read in via a barcode or RFID scanner connected to 
the RS 232 port, and comments can be entered with the help of 
the softkeys.
IZYTRONIQ User Software for PC
IZYTRONIQ is a test software developed from scratch. It enables 
the user to visualize and manage the entire testing procedure for 
all our test instruments and to document it in an audit-proof man-
ner. For the first time, it is thus possible to combine the test and 
measurement data from a great variety of test instruments and 
multimeters in one test and generate one report report thereof. 
The intuitive user guidance and modern design provide for quick 
access to all functions.
The software is available in different sizes and versions for trades, 
industry and vocational training purposes.
