6.3.2.1 Sampling the measurement channels
The DIGIFORCE
®
9311 lets you sample signals using a combination of time interval (Δt), X -interval and
Y- interval (ΔX, ΔY). This provides flexibility while also letting you compress the measurement recording. It
means that you can use just a few measurement points to record curve regions containing a constant or
steadily changing signal, whereas you can use more points when you need to record and reproduce
steep signal slopes or alternating waveforms.
Note: When setting the signal sampling, don't forget that there is a maximum memory capacity for the
measurement curve data. The DIGIFORCE
®
9311 can store a maximum of 5000 value pairs per
measurement. Thus with the fastest possible sampling time of 0.1 ms per sample, the curve
memory is full after 0.5 s.
Parameters in the "Measurement mode, Sampling" menu (M19)
X sampling
On / Off Enable/disable
X sample rate <value input> Enter the sample interval for the X-channel
For values that are less than the channel resolution,
the smallest available sample interval is used
automatically.
Range 0.00001 to 999999
Y sampling On / Off Enable/disable
Y sample rate <value input> Enter the sample interval for the Y-channel
For values that are less than the channel resolution,
the smallest available sample interval is used
automatically.
Range 0.00001 to 999999
t sampling On / Off Enable/disable time-based sampling
t sample rate
<value input> Enter the sampling time interval here
Range 0.0001 to 99999.0 seconds
6.3.2.2 Measurement curve reference
The DIGIFORCE
®
9311 provides the following X-references for the measurement curve:
Parameters in the "Measurement mode, Reference" menu (M19)
Absolute
Absolute
Final force Final force
Y ref. line >> Crossing above Y reference line
Y ref. line << Crossing below Y reference line
Y trigger >> Crossing above Y trigger threshold
Y trigger << Crossing below Y trigger threshold
Note: For the "Crossing trigger threshold" reference, the DIGIFORCE
®
9311 does not start saving
curve data until the trigger event has occurred. The measurement, however, must be started
before the trigger event.
