BRONKHORST HIGH-TECH B.V.
Potmeters for controller parameter setting are accessible via holes in the rear panel.
Potmeter:
P6: controls the valve quick start-up voltage. Set for optimum fast response behaviour from zero
setpoint. (optional)
P3: (flow control only) Controls the output differentiating network. This determines the dynamic
response characteristic of the system.
P4: (flow control only) Controls the D-action of the control circuit.
3.2 Connection to measuring devices
The instrument connector is a female sub-miniature 9-pin D-connector. The pin designation is according to the
