By channel 3. This setting is only available if the unit is
equipped with three channels. The subsequent parame-
ter
t-off
is used to specify the switch-off threshold. The
sensor is switched off when the pressure on channel 3
exceeds the switch-off threshold.
5.2.9
Switch-off threshold (
t-off
)
This parameter is only available if the sensor deactivation
parameter is set to
CH 1
,
CH 2
or
CH 3
. See Chapter 5.2.8
Sensor deactivation (S-oFF),

The
t-off
parameter is used to specify a switch-off thresh-
old. The sensor is switched off when the pressure on the
respective channel exceeds the switch-off threshold.
