TEST
Press the
TEST
button to start the measurement. The measurement stops automatically.
When the
TEST
button is pressed, the device checks that the contact voltage is less than U
L
. If not, it does not
make the loop impedance measurement.
This symbol invites you to wait while the measurement is in progress.

3.7.3. CONFIGURING THE MEASUREMENT
Before starting the measurement, you can configure it by modifying the parameters displayed:

A
k A
To activate the alarm on Ik.
To set the alarm threshold (see §3.14). As default,
the threshold is set to 10 kA.
The device proposes choosing the voltage for the Ik calculation from among the following values:
U
LN
(the measured voltage value),
the voltage of the old standard (for example 220 V),
the voltage of the current standard (for example 230 V).
Depending on the voltage U
LN
measured, the device proposes the following choices:
if 170<U
LN
<270 V: U
LN
, 220 V, or 230 V.
if 90<U
LN
<150 V: U

, 110 V or 127 V.
if 300<U
LN
<500 V: U

, 380 V or 400 V.
