How high are sampling and processing rates in the ClipX?
The measurement channels are sampled and processed at 19.2kHz. Calcu-
lated channels are processed at 1kHz. Values are outputted via the analog
output at 19.2kHz, and via the fieldbus interfaces at up to 4kHz. The digital
inputs and the flags or bits for the outputs are analyzed after 1ms at the latest in
the event of a change.
How high is the resolution and accuracy of the ClipX?
The measurement channels have 32-bit resolution. This allows even very small
signals in the partial-load range to be measured accurately and reliably. The
accuracy class of full bridge strain gages is 0.01%.
Can the channels of adjacent ClipX devices be offset?
Yes. The value transmitted over the ClipX bus of a ClipX can be processed, i.e
in calculations or functions such as peak value, captured values, etc. Note that
the values from the ClipX bus might have a delay of up to 1ms relative to your
own values.
How many parameter sets/measurement programs are there in the ClipX,
and how long are the switching times?
A maximum of 10 parameter sets can be used in the ClipX. The switching time
is normally 0.1s. If sensor inputs, measuring range or filters are changed, the
ClipX waits 2.5s before outputting measured values again. This suppresses any
switching peaks and transient responses.
What happens if the power supply fails while a parameter set is being
saved?
The parameter set will be destroyed, and after restarting the ClipX is returned to
its factory settings. To avoid this, we recommend backing up the device settings
to PC.
What happens if the power supply fails during a firmware update?
If anything goes wrong when updating the firmware, such as if the power fails,
the ClipX initially restarts with the old firmware, or the device loads and initial-
