Display with Selectable Language
Menus, setting options, measurement results, tables, notes and
error messages as well as schematic diagrams appear at the
LCD.
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 can 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
connection errors, which are indicated in a connection picto-
graph.
• Errors within the electrical system (no mains or phase voltage,
tripped RCD) are indicated at 3 LEDs and in 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 tester is shut
down automatically when the batteries are depleted. A micropro-
cessor controlled charging circuit is used to assure safe charging
of rechargeable 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.
USB Port
Measurement data are transmitted to a PC via the integrated USB
port, at which they can be printed in report form and archived.
PC Database and Report Generating Software – ETC
ETC test software offers lots of helpful options for data collection
and management:
• Acquisition of all important data for reports in accordance with
IEC 60364-6
• Test reports (ZVEH) can be generated automatically.
• Created structures can be saved to memory and loaded to
the test instrument as required via the USB port.
• Distribution structures with electrical circuit and RCD data can
be individually defined.
• Data export to Excel, CSV and XML formats
• Editing of device selection lists
Instrument Updates
The test instrument can always be kept current because the firm-
ware/software can be updated via the USB port. Updating is exe-
cuted during the course of recalibration by our service depart-
ment, or directly by the customer.
