Enwatch Unit 19
Bias voltage reading
When you define a process measurement of DC in the Emonitor software, the Enwatch unit reads the transducer bias
voltage.
24V means open circuit, 10V is OK.
Maximum number of averages that can be supported
Number of samples required: Lines x 2.56 + lines x 2.56(#avg -1) x (1 -%overlap)
Max number of samples per configuration: 32768
Max number of averages = ((32768 / (lines x 2.56)) - 1) / (1 -%overlap) + 1)
The following table shows the maximum number of averages versus the number of lines and percent overlap for non-trigger
point.
The following table shows the maximum number of averages versus the number of lines and percent overlap for pre-trigger
point.
Signal detection
RMS, Peak, Peak-Peak
Configuration downloading
Route mode configuration downloads to Flash memory
Live mode configuration downloads to RAM
Note: You can reduce number of average or increase percent overlap to reduce amount of memory used.
