INFICON D-TEK Select Bedienungsanleitung Seite 7

To "zero" D-TEK Select, press the HI/LO switch once. Both the HI and LO
sensitivity indicators 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 HI/LO switch until the HI
sensitivity indicator becomes steady.
NOTE: When D-TEK Select is turned on, it will always default to automatic
zeroing mode.
Recharging the Power Stick
A fully charged power stick should provide power for approximately 6.5 hours of
continuous operation. When the battery is fully depleted, D-TEK Select will shut
down. To show the battery is depleted, the green ON LED, the last yellow leak
LED, and the amber battery charging LED will flash. Recharge the D-TEK Select
by connecting the supplied AC power adapter or cigarette lighter adapter.
NOTE: D-TEK Select does not need to be fully charged to operate nor fully
discharged before recharging.
W A R N I N G
Do not attach any other power cords to D-TEK Select's power jack
except the AC power adapter and DC cords designed for this
instrument.
The battery charging indicator (rear left side) will flash when the power stick is
charging, changing to steady illumination when the power stick is fully charged.
Allow 10 hours for a full charge.
D-TEK Select will operate using the AC power adapter. Connecting the supplied
AC power adapter will allow operation of the detector while the power stick
charges.
