Fig. 4 Keys and LED‘s on the sensor
(1) select/zero key Measurement mode:
Sets analog output to
„Master“ or „Mid-point“, see Chap. 6.7, see
Chap. 6.8.
Setup mode: For changing the sensor
parameters, see Chap. 6.5.
(2) function/enter key
For switching between measurement mode
and setup mode.
(3) LEDs, see Fig. 5.
IMPORTANT!
Keys can be locked
via the serial interface,
