Reset The Pressure Sensors - GE AKTA pilot 600 User Manual

5.4.1

Reset the pressure sensors

Introduction
The ÄKTA pilot 600 system is fitted with three pressure sensors, for monitoring system
pressure, pre-column pressure and post-column pressure.
The pressure sensors should be reset at intervals by setting the reading for atmospheric
pressure to zero in UNICORN software. The pressure sensors themselves are not acces-
sible to the user.
This section gives instructions for resetting the pressure sensors.
Maintenance interval
The pressure sensors should be tested every week, or when the the ambient temperature
has changed by more than 5°C. Reset the pressure sensors if the atmospheric pressure
reading is outside the range ± 0.02 MPa (0.2 bar, 2.9 psi).
Tubing connections
Resetting pressure sensors involves disconnecting tubing from the appropriate module
according to the table below.
