For some sensors
special functions
are available in this context:
1. With pH probes, if the two keys
ENTER
and
F
are pressed during switch-on,
the locking is only temporary, i.e. until the device is switched off and set to
3. An undesired adjustment can then be avoided.
2.
Dynamic pressure probes
are very delicate and should be adjusted in an
unpressurized state before each use (i.e. disconnected hoses or Pitot tube
out of flow). The correction value must be entered before the conversion
'pressure-to-velocity' is performed. For the ranges L840 and L890 an
adjustment is possible even if the channel is locked.
The zero point error is temporarily being written into the calibration offset
until the switch-off is performed.
3. With the following sensors, a
slope adjustment
is performed in the same
way for the corresponding calibration value:
