Input signal type and range

You can not change the input type during set-up mode. The input is

either current or voltage according to the components used when the

unit was built.

The input range is determined by the values supplied during

calibration. So, if you change the range displayed in setup, you will

have to calibrate the inputs.

mping Factor

The PTX800A uses digital filtering to smooth the input signal. The

damping factor sets the amount of filtering from minimum damping

(factor of one) to the maximum (factor of ninety nine).

ansfer Function

To use the PTX800A with square law rate measuring devices, like

differential pressure cells, set the transfer function to square law.

Otherwise use a linear setting. For more complex relationships

between rate and signal level you can use a CLC/AR to linearise your

input signal.

w cut-out rate

To prevent accumulated errors at low input levels, you can set a low

cut-out rate. When the input is below this value the total does not

increase.

tal decimal point

The total decimal point position sets the number of decimal places for

the total display. Totals are displayed using the full eight digits.

te decimal point

Sets the number of decimal places for the rate display. Rates are

displayed as five digit numbers.
