Using the Manual Zero Mode
The D-TEK Select's automatic suppression of background contamination can be
disabled, allowing for a continuous display of a leak without "zeroing it out". When
the D-TEK Select is set in the manual zero mode, the technician may manually
reset or zero the detector.
To initialize this function, press and hold the HI/LO switch for 5 seconds. The "HI"
sensitivity indicator will flash to alert the user the detector is in manual zero mode.
Increases in concentrations of refrigerants will be displayed by the illumination of
the yellow LEDS. For best test results, allow the D-TEK Select to warm up for
5 - 10 minutes before engaging manual zero mode.
To "zero" the D-TEK Select, press the HI/LO switch once. Both the HI and LO
sensitivity indictors will flash for a few seconds while the detector measures and
sets a new background base level. Any increase in concentrations of refrigerant
above this base level will be displayed.
To turn off the manual zero mode, press and hold the HL/LO switch until the HI
sensitivity indicator becomes steady.
NOTE: When the D-TEK Select is turned on, it will always default to the
automatic zeroing mode.
