This display screen confirms that the doors are open and the sensors are ready
for auto-zeroing. First, select the Main Glove Box Chamber key (Box) and
wait for complete calibration to zero pressure. Next, select the Transfer
Chamber key (CH) and wait for complete calibration to zero pressure. Once
the key adjacent to “Save” is pressed, the new sensor offset valves for both
chambers are stored, and this pressure becomes the zero point for both
chambers. Select the back key two times when calibration is complete to
return to the three main modes of operation.
Pressure Control Foot Switch (Labconco #5243600)
The three position (increase gas/fill, off, purge/decrease gas) foot switch should
be plugged into the back panel of the Labconco Pressure Controller. The Foot
Switch has the same effect as pressing the Purge and Fill keys on the display
panel. The action of the Foot Switch depends on what mode of operation is
shown on the display. If the transfer chamber screen is shown on the display, the
Foot Switch will control the Transfer Chamber gas in and gas out valves. If the
display shows the Glove Box Pressure Control or the Glove Box Purge/Fill, the
Foot Switch will control the Glove Box Main Chamber gas in and gas out valves.
The foot switch will not work when the pressure/vacuum inside has exceeded the
user preset limits shown on the display.
