Total scaling factor

The total 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).

mber of samples

The PTX800A calculates the rate every 260 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

, the analogue output and rate display will be updated every 2.6 s.

Rate timebase

The rate timebase setting sets the timebase for the rate display. It can

be set to days, hours, minutes or seconds.

splay rate or total

Use the display rate/total setting to choose the measurement that will

normally be on display.

able 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.

arms 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.

arm 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.
