Rate scaling factor
The rate scaling factor sets the ratio between the total display and the
rate display. It must be a power of ten (i.e., 1000, 100, ..., 0.01, or 0.001).
Number of samples
The PTX800D calculates the rate every 60 mS. The analogue output
and display are then updated from the average over the programmed
number of samples. For example, if you set the number of samples to
10, the analogue output and rate display will be updated every .6 s.
Rate timebase
The rate timebase setting sets the timebase for the rate display. It can
be set to hours, minutes or seconds.
Show rate or total
Use the display rate/total setting to choose the measurement that will
normally be on display.
Enable Reset key
The front panel reset key can be used to reset the total. You can
disable this feature (for added security) using this setting.
Alarms disable/enable
If you do not need alarms, you can disable them. This simplifies the
setup process, as all of the parameters related to the alarm operation
are skipped.
Alarm type
Each alarm channel can monitor the total or the rate. Total alarms
operate when the setpoint is exceeded. A ‘total’ alarm trip condition
clears when the total is reset.
Setpoint
The setpoint is the display value at which an alarm activates. It can be
changed during normal operation if the setpoint security option is off.
