If necessary, adjust and calibrate the temperature of the bath. If the temperature has not changed,
temperature calibration is not necessary.
Note:
Sensor training data is associated with the temperature setting of the
bath. When a tube is changed and the bath temperature is either kept the
same or changed to a temperature at which a tube was previously trained,
the CAV displays that the sensors are trained. This is correct. The sensors
must be trained whenever a tube is changed.

Replace Power Supply
The CAV 4.1 power supply is a switching regulated power supply designed to handle 90 – 240 V
AC
. To
accommodate different locations, only the MAINS AC power cable needs to be changed.
Caution:
The power supply is easy to replace. The side panels do not need to be
removed to access the power supply attachment point. It is not
connected via cable. Instead, a mating coupler is attached to a
bulkhead in the chassis.
1.
Turn off the CAV 4.1 and unplug it from the MAINS AC power.
2.
Remove the power cable.
3.
Remove the four screws securing the power supply assembly to the chassis.
4.
Firmly pull the power supply assembly from the chassis.
