for the measurement of loop resistance, determination of
short-circuit current and the display of applicable fuse ratings.
In addition to complete testing for the effectiveness of RCDs, the
instrument is also
capable of phase sequence analysis, as well as the measurement of
voltage and frequency.

their respective electrical circuits, distributors and buildings with
the alphanumeric keypad.
- Unambiguous GO / NO-GO decisions are made possible with
LEDs and display messages.
