Calibrating Pressure Settings
WARNING! You must remove the tubing from the pressure sensor before you
calibrate it. The sensor must be at atmospheric pressure when you start.
You can calibrate sample pump pressure, system pressure, and column switching
valve pressure to zero. If pressure is not reading zero or close to it, you can reset the
pressure values to zero.
To calibrate a pressure setting
1. Select a pressure module in the Calibrate dropdown list at the top of the
Calibration dialog box.
2. Follow the dialog box instructions to reset the pressure setting to zero.
Note: To calibrate pressures at the upper limit, call Bio-Rad Support.
