Adjusting Flow Valves
The Vent valve control on the instrument’s front panel adjusts the flow rate through the vent valve. If
the flow rate is high, you may not be able to achieve accurate dosing pressures. If the flow rate is low,
the length of the experiment will be increased. Close the valve slightly if the instrument is having diffi-
culty achieving dosing pressures within the specified tolerance. Open the valve slightly to speed up the
experiment.
The vent valve rate should be adjusted prior to the experiment to achieve a range between 5 to 15 sec-
onds per 1 bar decrease by monitoring the pressure on the manual control screen while adjusting the
Vent valve control.
