Setpoint is redirected to Valve Out with
controller idle
Analog input is redirected to Valve Out with the
controller idle
After power-up the control mode will be set to 'Analog input' or 'BUS/RS232', depending on the customer's default setting for
analog or digital operation. Except when the actual control mode setting is other than 0, 1, 9 or 18 the actual control mode setting
is maintained. For more information see parameter 'IOStatus', section 4.2.2.
For dual interface operation or slave factors, see document nr. 9.17.023: Operational instructions for digital
instruments. http://www.bronkhorst.com/files/downloads/

4.1.2 Fluid information
The following parameters give information about the selected fluid range.
Fluid Number
The 'Fluid number' is a pointer to the set of calbration parameters. Each selectable fluid has its own set of calibration parameter
values. Parameter value 0 = fluid 1 and parameter value 7 = fluid 8. Up to eight fluids can be stored in an instrument. Default value
= 0 (fluid 1).
Fluid Name
0x8188…0x818C/33161…33165
This parameter consists of the name of the selected fluid number, e.g. 'Air'.
Fluid Unit
0x81F8…0x81FB/33273…33276
The 'Fluid Unit' can be read by parameter 'Capacity Unit'. This parameter contains the unit in maximal 7 characters.
Fluid Capacity (@100%)
0x8168…0x8169/33129…33130
Capacity is the maximum value at 100% for direct reading in sensor readout units.
Fluid Capacity (@0%)
0xA1B0…0xA1B1/41393…41394
This is the capacity zero point for direct reading in sensor readout units.
For using the 'Capacity Unit Index' or 'Capacity Unit' parameters, see document nr. 9.17.023:
