4.4 STANDARD OR ADVANCED MODE
The earth clamp can be used in two ways.
■
The
Standard
mode makes the standard loop ohmmeter clamp measurements.
■
The
Advanced
mode is used to refine and complete the measurements:
- Impedance referred to the selected frequency.
- Contact voltage.
- Resistive and inductive fractions of the loop impedance.
The choice of the
Standard
or
Advanced
mode and the alarm thresholds are
parameterized in the
SET-UP
menu. See §8.5, menus 4, 5, 6, and 9 for details.

4.6 USE OF THE
HOLD
KEY
This function, available in the
Ω+
A
and
A
measurement modes, freezes the
display of the measurement as soon as the
HOLD
key is pressed. The
NOISE,
clamp open (
), and alarm overshoot ( ) icons are visible if they were active.
With the
HOLD
state active:
■
The ►
key is active and can be used, in
Advanced
mode, to display the
various measurement screens.
■
The
MEM
key is active and can be used to record the values displayed.
■
The
HOLD
key is used to exit from the
HOLD
state. The
icon goes off
and the device returns to the previous function.
4.7 USE OF
PRE-HOLD
If the
Pre-Hold
mode was activated in the configuration (see §8.5, menu 11),
opening the clamp places the device in a state identical to the
HOLD
mode for as
long as the clamp is open. The utility of this function is that it makes it easy to
freeze the measurement with one hand, in particular when access to the
HOLD
