7.5 Pitot factor(not available with 200kPa Range)
This step, represented by the '
Pit
' symbol in the bottom line of the display,
allows the user to enter the factor for a pitot tube.
Selects which digit of the display is to be changed (digit will flash).
Increases the selected digit in increments of +1 (0...9
0). If the set
value exceeds the limits of the setting range, it is not added onto the
next highest digit (no overflow); the digit in question is instead set back
to 0.
Exits the entry mode for the pitot factor and continues on to the next
step: entering the 2V pressure for the analogue interface.
7.6 Setting the scale for the analogue output
This configuration parameter is used for setting the pressure at which the
analogue output reads out 2V. Users have the option here of setting the
analogue output to any desired final pressure between 20 and 100% of the
measurement range. While operators may enter final pressures <20%, doing
so will decrease the DA resolution. The bottom line of the display will show the
code '
AnH.
'
Selects which digit of the display is to be changed (digit will flash).
Increases the selected digit in increments of +1 (0...9
0) If the set
value exceeds the limits of the setting range, it is not added onto the
next highest digit (no overflow); the digit in question is instead set back
to 0.
Exits this mode and continues on to the next step: entering
attenuation.
7.7 Analog offset for +/- measurement
7.8 Attenuation
It may be desirable to determine and display an average value over a specific
period if input pressures fluctuate significantly. This parameter allows the user
to set the number of measured values to be used to determine an average.
Assuming a display rate of 2 measurements per second, this value (1...20)
sets an attenuation time between 1 and 10 seconds. The bottom line of the
display will show the code '
dAn.
'
Selects which digit of the display is to be changed (digit will flash).
