This icon is used to do a reservoir fluid temperature sensor 2-point calibration, the sequence does
not matter. The procedure requires a calibrated reference thermometer. Before the calibration can
be performed the fluid temperature must be stabilized at 35°C and then again at 70°C.
Note
Performing a calibration at any other temperatures will result in an error display .
Once the temperature has stabilized at 35°C, or
70°C, press
then use the arrow key to
change the temperature to match the reference
thermometer. Once the desired value is displayed
press
to save the change or
x
to
not save the change.
Press to return to the home screen. Repeat the procedure for the other temperature.
These icons represent the low fluid protection status. The top indicates it is enabled, the bottom
is disabled. Press
to toggle between enabled/disabled. Press to return to the
home screen.
Note Low fluid protection is enabled by default.
When enabled and the reservoir level nears empty the bath will shut down and, if enabled, the
alarm will sound. The controller will also have an error display,
. See Chapter 6.

GP bath reservoirs can be filled with thermal beads instead of water. These icons are used to
select/deselect the reservoir bead mode.
Press to toggle between on and off. Note For safety considerations, the mode
automatically derates the bath’s heater performance, and it turns off low fluid protection so the
beads don’t trip the alarms. This mode also derates the bath’s stability and uniformity capability.
