Inputsignaltypeandrange
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.
DampingFactor
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).
TransferFunction
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.
Lowcut-outrate
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.
Totaldecimalpoint
The total decimal point position sets the number of decimal places for
the total display. Totals are displayed using the full eight digits.
Ratedecimalpoint
Sets the number of decimal places for the rate display. Rates are
displayed as five digit numbers.
