CALIBRATION PROCEDURE
1) Hold in “CAL” whilst applying mains power to the unit.
2) Release the “CAL” when two audio beeps are observed.
3) After a second audio beep is observed a “SET FAN SPEED” prompt message in a box will
appear on the LCD display.
4) The system must now be left for a minimum of 15 minutes to allow the Figaro sensor to
reach operating temperature ( if fitted ).
5) Using a calibrated handheld anemometer set the face velocity airflow to the required level
using the “FAN UP” & “FAN DOWN” switches to alter the fan speed.
6) When the required face velocity has been set and allowed to stabilise press the “CAL” switch
again, an airflow display in M/sec will appear on the LCD.
7) After the airflow reading has stabilised, use the “FAN UP” & “FAN DOWN” switches to set the
displayed airflow to match the calibrated handheld anemometer.
8) When the desired reading is observed press the “CAL” switch once, the audio will beep twice,
the fan & alarm LED will alternate on and off for approximately six seconds during which time
the airflow and saturation alarm settings are being stored.
9) The display will then return to the main run screen.
NB The airflow may alter from the target set point for a short period before stabilising,
to avoid this switch the power off and on again.
10) The saturation alarm function is disabled for 5 minutes from initial power up. During this
period no text is displayed. When enabled, FILTER OK is displayed. If no gas sensor is fitted, no
text is displayed after the 5 minute warm up period.
11) If the system detects a saturation condition of the filter, the FILTER OK text changes to
FILTER SATURATED , the alarm text flashes every second and an audio alarm sounds. This can
be muted using the alarm mute switch on the membrane panel.
