Modes of operation
Enhanced trigger circuit Enhanced start circuit
Probes subjected to high levels of vibration
or shock loads, may generate trigger signals
without having contacted any surface. The
enhanced trigger circuit improves the probe’s
resistance to these effects.
When the circuit is enabled, a constant nominal
10 ms delay is introduced to the probe output.
It may be necessary to revise the probe’s
program software to allow for the increased
stylus overtravel during the extended time delay.
Factory set to OFF.
Probes subjected to particular forms of light
interference may accept spurious start signals.
The enhanced start filter improves the probe’s
resistance to these effects.
When the filter is enabled, an additional 2 s delay
is introduced to the probe activation (switch-ON)
time.
It may be necessary to revise the probe program
software to allow for the increased activation
time.
Factory set to OFF.
Low power (battery save) mode
Where the separation between probe and OMM
or OMI is small, the low power mode may be
used. In this mode, the optical transmission
range will be reduced by 30 %, so battery usage
life will be extended. See battery life expectancy
(page 7).
Factory set to STANDARD POWER.
