Pressure Controller Operating Instructions
General Description
These operating instructions are designed for the operation of the Pressure Controller used with
Labconco’s Precise Glove Boxes. The Pressure Controller performs three automatic modes on
the glove box. First, it cycles the purging/filling process in the main glove box chamber and
transfer chamber up to 199 cycles. Second, it regulates vacuum/pressure between -5 and +5
inches of water gauge in the main glove box chamber through the glove box pressure control
program mode. Third, it regulates vacuum in the transfer chamber between 0 and -29 inches of
mercury during the purging/filling process.

Option 1
Units of Measure: If this option is selected, the key adjacent to “Next” is used to select pressure
units of inches of water/inches of mercury or mBar.
Helpful conversions are as follows:
1 mBar = .39 inches of water column
1 mbar = .0292 inches of mercury
1 inch of water = 2.52 mBar = .0737 inches of mercury
1 inch of mercury = 34.25 mBar
All pressures are measured with respect to atmosphere pressure.
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.
Labconco Operating Instructions 5242600, Rev. B 4/27/07, ECO E275 9 of 20
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.

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.
