bag after test is complete. Seal the bag to prevent the media from
drying out. Replace Test Vial when the green color is no longer visible.

MANUAL CALIBRATION MODE:
This mode may be useful when more control over the calibration is
required such as in heavily contaminated areas but may also be helpful when
searching for smaller leaks. In this mode the detector recalibrates to ambient
levels, but only when the user chooses to do so. The calibration will remain constant
when searching for small leaks.
TO USE THE DETECTOR IN MANUAL CALIBRATION MODE:
Select the sensitivity mode required High, Medium or Low. Press and hold the
Sensitivity button and release the button when the High, Medium or Low indicator
on the display starts flashing.
NOTE: when in this mode, the Sensitivity level indicator will blink (flash) continuously.
Reset or clear the alarm by pressing the Sensitivity button again.
Continue to reset the alarm as needed until the leak source is pin-pointed.
TO RETURN TO THE AUTOMATIC CALIBRATION MODE:
Press and hold the Sensitivity button until the sensitivity indicator stop flashing.
The Sensitivity level indicator will stop blinking and will stay on.
NOTE: the sensitivity levels can only be changed in Automatic Calibration mode.
TO CHANGE SENSITIVITY LEVELS WHILE IN MANUAL MODE:
Return to Automatic mode, select the desired level and return back to Manual mode.
1 Remove the plastic seal label on top of the Leak Test Vial by pulling it off (see fig. below).
2 Turn on the detector and allow the unit to complete the warm up mode
(Sensitivity level set at MED).
3 Place the sensor close to the small hole in the top of the Leak Test Vial.
The beep rate should increase and the Digital Leak Size Indicator Graph should display a
minimum of 3 bars indicating that the sensor and electronics are working properly.
BACKLIGHT
