Functions common to F11N and F13N
Clamping the cable.
The specially designed shape of the jaws enables large
cross-section conductors to be enclosed, and satisfi es the
majority of high current applications.
A 2 busbars
B 2 cables
C 1 cable
Reminder : The clamp must only enclose a single phase
conductor, which can be physically subdivided into 2
smaller sections. In principle, the clamp cannot measure
current in a conductor that includes the phase cable and
the neutral cable.
1 Jaws
They enclose the cable to measure AC CURRENTS.
The jaws are designed with an «anti-pinch» system.
The red color was chosen to identify the zone which is
potentially dangerous during measurement of AC currents.
2 Guard
The non-slip guard protects the user from accidental
contact with an uninsulated conductor when clamping a
cable.
3 Trigger
To open the jaws.
4 MAX button
To activate the max value function on A and on V and for
the diode test function.
Typical acquisition time : < 500ms (except for calibre
change).
NB : This button is inoperative on frequency and resistance
measurement
5 HOLD buttons
This function makes it possible to measure in a harsh
environment, or little lit, by memorizing the value for a
differed reading.
This function is active for all the positions of switch 6 .
It is activated by pressing one of the two keys 5 and
released by pressing one of these two keys again (two-
way switch system).
