To start the calibration, use the Labconco 1000 Manual and enter
the “CALIBRATIION” mode on the display. Follow the
instructions on the display and alter the low and high exhaust
volumes with the speed control. The following suggested inflow
face velocity speeds are recommended to successfully calibrate.
Typical low air alarms are set 10-30 fpm below operational speeds.
Typical yellow cautions are set 3-10 fpm above the red low air
alarm. Be sure to enter “Done” after completing the calibration in
“SETUP.” Once completed, go to “RUN” and hit “ENTER.”
