Alarm Thresholds; K Coefficient - Chauvin Arnoux C.A 25 Mode D'emploi

When only one value, or the cancelling symbols have been chosen, the validation
is done :
- either by pressing
disappears from the display.
- or by changing to another programming function using
SCAN
or
- or by turning the rotary switch to another measurement function, except OFF.
The instrument then changes to measurement function.
Switching from "rpm" to "OFF" when the instrument is in PRGM mode results in the
loss of the current non-validated value. The values previously input remain in the
memory.
The information contained in the memory can be read in the same way as for
programming, except that the buttons
are not pressed.
Alarm thresholds (CA 27 only)
The programming of the alarm threshold requires the previous selection of
, by a press (PRGM on the display).
PRGM
Two thresholds can be set. Programming of these values is done by pressing the
button on programming mode.
ALARM
A first press on
threshold. A second press on
HI
displays and allows programming of a high threshold (HI AL).
AL
When a threshold is programmed and the ALARM function is activated, its symbol
appears continually on the display on the measurement function. The digital value
is constantly compared to this value. The result of the comparison positions the
symbols on the display and controls the buzzer (see use of this function in
paragraph ALARMS).
K coefficient (C.A 27 only)
The K coefficient is a multiplier applied to the value of the measurement, before it
is displayed on the digital and analogue displays.
