3.7.4 SELECT ANALOG OUTPUT (OPTIONAL)
The Analog Output Menu determines which data is sent to
the BNC analog outputs (REC 1, REC 2 REC 3, REC 4) at the
back of the Pressure Interface, four in total. Each output is
individually programmable. Any changes made to the analog
output will only affect the data collected by the external data
acquisition system. Therefore, it is important to check the
data acquisition setup when a change is made. The analog
output works in range of -2,5V to +2,5V.
Use SELECT to select the channel number to be changed.
Then press ENTER to go to the output set-up.
Use SELECT to select the line to be changed. Use Up and
DOWN arrows or DEFAULT to change/select a new set-up.
The following parameter in the Pressure Interface can be
selected as output on the analog channel.
Force, probe temperature, chamber temperature, pH1,
pressure regulation ON/OFF, Flow ON/OFF, (Optional: Digital
output 1, Digital output 2, Digital input 1, Digital input 2),
Pressure P1, Pressure P2.
When the parameter is selected press ENTER to save the
value.
The output range is -2,5V to +2,5V. The user can select the
parameter value that gives -2,5V and the value that gives
+2,5V. In this example -100mN is
-2,5V and +100mN is +2,5V. Selecting asymmetrical values is
also valid. They can be -2,5V = 0mN and +2,5V = 100mN.
OBS: REMEMBER TO PRESS THE ENTER KEY TO SAVE THE LINE CHANGES TO MEMORY
