Overview of Features Included with SECUTEST BASE, SECUTEST PRO and SECULIFE ST BASE(25) Test Instruments
1
10 A/25 A-R
PE
 measurements are only possible with line voltages of 115/230 V 
and line frequencies of 50/60 Hz.
2
Voltage mesurement inputs only with SECUTEST PRO (or device with Feature I01) and 
SECULIFE ST BASE(25) 
3
Terminal for 2
nd
 test probe for 2-pole measurement only with SECUTEST PRO (or de-
vice with Feature H01) and 
SECULIFE ST BASE(25)
4
Measurement of time to trip not possible in IT systems
5
No checking for reversed polarity takes place when the EL1 adapter is used.
Key
Alternative = 
alternative measurement 
(equivalent leakage current 
measurement)
Differential  = differential current measurement 
Direct = direct measurement 
LN(TS) = short-circuited conductors L and N of test socket
P1  = measurement with test probe P1 
P1-P2  = 2-pole measurement with test probe P1 & P2
PE-P1  = measurement between PE and test probe P1
PE(TS)  = protective conductor of test socket
PE(Mains)  = protective conductor of mains terminal
Overview of Differences in Features
* for voltage measurements or connecting current clamp sensors or AT3 adapter as 
well as for temperature measurement via RTD
Display with Selectable Language
The display panel consists of a backlit, color multi-display at 
which menus, setting options, measurement results, instructions 
and error messages, as well schematic and wiring diagrams 
appear.
The display and user prompting can be set to the desired lan-
guage depending on the country in which the test instrument is 
used.
Data Entry
Data can be entered, for example, via a barcode reader con-
nected to the USB port, a RFID scanner, a USB keyboard, or via 
the softkey keyboard when it appears at the display.
The touch screen of SECUTEST PRO (or devices with Feature E01) 
and SECULIFE ST BASE(25) allows for the convenient entry of data 
and comments while menu control is still based on softkeys.
