SECUTEST BASE / PRO and SECULIFE ST BASE(25)
Test Instruments for Measuring Electrical Safety of Devices
Data Interfaces
Structures set up in, and measurement data saved to the test instru-
ment can be imported to
IZYTRONIQ report generating software via the
USB slave port. Data can then be archived at the PC, comments can
be added with the software and reports can be generated.
The following input and output devices can be connected to the
two integrated USB master ports:
• An external keyboard and a barcode or RFID reader,
• USB stick for data backup
, import, export and reporting
•A printer
Software Update
The test instrument can always be kept current thanks to firm-
ware which can be updated via the USB slave port.
Report Generating Functions
All of the values required for approval reports or device logbooks for
electrical equipment (e.g. per ZVEH) can be measured with this
instrument. The measured data can be documented and archived
thanks to the measurement and test report that can be printed with a
thermal printer connected to the USB port, or stored to a PC.
Automatic Detection of Measuring Point Changes
During protective conductor measurement, the test instrument
recognizes whether or not the test probe is in contact with the
protective conductor, which is indicated by means of two different
acoustic signals. This function is very useful where several protec-
tive conductor connections need to be tested.
Mains Connection Analysis
Line voltage and frequency are measured and compared with the
data specified in the setup menu. Momentary voltage or nominal volt-
age in accordance with the standard is required, for instance in order
to extrapolate measured values for the leakage current measurement.
Automatic Detection of Mains Connection Errors
The device automatically recognizes mains connection errors if
the conditions in the following table have been fulfilled. The user is
informed of the type of error, and all measuring functions are dis-
abled in the event of danger.

measurements are only possible with line voltages of 115/230 V
and line frequencies of 50/60 Hz.

if the test person is highly insulated, the following error message may appear: „In-
terference voltage at PE of mains connection“
Analysis of DUT Connection and Condition
Depending on the measurement or how the DUT is connected, the fol-
lowing states are checked and displayed before measurement is begun.
* applies to M7050 with feature B00, B09 and B10
** applies as from version 1.7.0; previous condition ≤ 1.5 Ω or > 1.5 Ω , respectively

Our test instruments SECUTEST BASE(10), PRO and

BASE(25)
allow for the active testing of devices with a nominal current (load
current) of up to 16 A. The test socket of the respective test instrument is
equipped with 16 A fuses and the switching capacity of the internal relays
also amounts to 16 A. Starting currents of up to 30 A are permissible. For
devices under test which are expected to feature a starting current of more
than 30 A, we strongly recommend the application of a test adapter for
higher starting currents: e. g. test adapter of the AT3 series
I > 16.5 A
