Agilent TwisTorr 305 FS Remote Controller User Manual
Range
0-99 Gauge gas load type. The value is divided by 10 (entering 12
the controller will apply 1.2)
Enter here the correction factor for gas (necessary only if
gauge is connected).
0-10000 Setpoint 1 value. Enter here the threshold value for the R1
output, valid only if B0-B2 of Parameter Buffer Offset-21 is
equal to 0,1,2 or 3.
0-30000 Setpoint 1 Mask Time. Set here the time, measured from the
start pump event, while the R1 output is masked (not activated)
0-10000 Setpoint 2 value. Enter here the threshold value for the R2
output, valid only if B3-B5 of Parameter Buffer Offset-21 is
equal to 0,1,2 or 3.
0-30000 Setpoint 2 Mask Time. Set here the time, measured from the
start pump event, while the R2 output is masked (not activated)
0-30000 Vent Valve Opening Delay.
Set the delay time between the stop command and vent
opening. Valid only in "purge/vent auto mode" (Parameter
Buffer, Offset 20, B0 = 0). 0 = infinite (the valve will never open).
0-30000 Vent Valve Open Time. Set how long the vent will remain open,
then both purge and vent will be closed. Valid only in
"purge/vent auto mode" (Parameter Buffer, Offset 20, B0 = 0). 0
= infinite (the valve remain open till next start command).
1-99 Setpoint 1 Hysteresis. Set the Setpoint1 hysteresis around the
nominal value
1-99 Setpoint 2 Hysteresis. Set the Setpoint2 hysteresis around the
nominal value
0-99 Setpoint 1 Pressure Value Mantissa.
Set the mantissa of the exponential value of the R1 setpoint
(format X.XE-XX) when it is used for pressure monitoring
(Parameter Buffer, Offset 21, B0-2 = 4). The value set here is
divided by 10, that means 11 = 1.1
-10 - Setpoint 1 Pressure Value Exponent.
+10 Set the exponent of the exponential value of the R1 setpoint
(format X.XE-XX) when it is used for pressure monitoring
(Parameter Buffer, Offset 21, B
