3.6 Pretravel check on the measuring sensor
This function allows, if programmed, to check the transducer's efficiency. The PreTRAV1 and
PreTRAV2 variables are programmable in the range from – 0,040 to – 5,000 mm (- .00155" to -
.19685") and allow to limit the pretravel value of the transducer.
If a single sensor is connected to the Quick Read (PROBE = Probe1), in the main menu only the
variable PreTRAV1 appears; if two sensors are connected (PROBE = Probe1&2), both variables
PreTRAV1 and PreTRAV2 appear.
Using this function the transducer is over range (OVER RNG is displayed) when it is not in
measuring position (i.e. when the transducer position is corresponding to a value bigger than the
programmed pretravel value).
The transducer might be damaged if the gauge is free and a measuring value (typically near to
zero) is displayed.
The following table shows what is displayed when this check is enabled, according to the
number of connected transducers.
