Option 2
Restore Defaults: The restore defaults option restores all control settings to the initial
programmed settings which are listed in the back of these operating instructions.

Option 3
Calibration: The pressure sensors inside the controller can be calibrated
using atmospheric pressure (single point calibration) or atmospheric pressure
and a specific pressure level (two point calibration). Two point calibration
provides increased accuracy; however, Labconco recommends that only the
single point calibration be used because it does not require a calibrated
pressure measurement standard. When “Calibration” is selected, the display
screen below appears. The keys adjacent to the up and down arrows on the
lower right of the display are used to select one of the options. After toggling
up or down, push the NEXT key to select the option.

Note: If option 2 or 3 above is selected, an accurate, traceable pressure
measuring device must be connected to the Labconco pressure sensors.
Consult Labconco for further instructions for this type of calibration.

Option 1 above is normally selected. Both doors must be open so
atmospheric pressure is available to both the glove box main chamber and
transfer chamber. Select the NEXT key to advance the screen to sensor
offset for Option 1. The display screen changes are shown on the next page
for Option 1.
