CAUTION: If you select "SAVE" at the end of the calibration, you overwrite one of the pre-configured
calibrations (or one you may have already modified) in the probe! The original

RS485 adapter (e.g. SM-USB).

To start measuring the material, press the "Measure" key
again. Four measurements are taken to increase the accu-
racy. An average of these measurement values is then cal-
culated. The measuring time is approximately 20 seconds.
When the measurement is finished, the measured pulse
transit time is displayed briefly.
NOTE: Before you start measuring, make sure that the
rods of the probe are fully immersed in the mate-
rial to be measured. The probe must remain in the
material for the entire duration of the measure-

memory set at the start ("Save"). The selected memory is
only overwritten once the "Measure" key
word "OWN:" now appears in front of the original memory
name to clearly indicate which memory has been overwrit-
