For each alarm to be defined, select:
- The target of the alarm (Vrms, Arms, VPST,
Vcf, Acf, Hz, Akf, Vthd, Athd, W, VAR, VA,
DPF, PF, Tan, Vh, Ah, or VAh - see the table
of abbreviations on page 9).
Note: VAh is meaningful only in the single-
phase context.
- The order of the harmonic concerned (for Vh,
Ah, and VAh only).
- The direction of the alarm (> or < for Hz,
Vrms and Arms).
- The alarm triggering threshold (possible
adjustment of the power of 10 of the unit for
W, VAR, and VA).
- The minimum duration of overshoot of the
threshold for validation of the alarm (in
minutes, seconds, or, for Vrms and Arms
only, in hundredths of a second).
- Activation (ON) or deactivation (OFF) of the
alarm.

Example 1: this alarm line is read as follows:
Hysteresis 1%
3 ON Arms <0010A 01s
The hysteresis is 1%. The alarm can be triggered
(On). During an alarm campaign ( ), alarm no. 3
will be triggered if the RMS current (Arms) is less
than 10 A (<0010A). The alarm will be stopped
when the current exceeds 10.1 A (10 A + 1%
hysteresis). The alarm will be recorded in the alarms
log if it lasts 1 second or more (01 s).
Example 2: this alarm line is read as follows:
Hysteresis 1%
1 ON Vh 2 >10.0% 10s
The hysteresis is 1%. The alarm can be triggered
(On). During an alarm campaign ( ), alarm no. 1
will be triggered if the voltage level of harmonic 2
(Vh 2) exceeds 10% (>10.0%). The alarm will be
stopped as soon as the voltage level of harmonic 2
falls back below 9.9% (10% - 1%). The alarm will be
recorded in the alarms log if it lasts 10 seconds or
more (10 s).

was:
- No, you return to the Parameterising menu.
- Yes, the message Data being erased is
displayed. The instrument then switches
itself off automatically. When it is next
started, the menus are in English; the C.A
8230 contains no information (factory
configuration).
Note: pressing the
