Filter Cartridge High / Low Indicators Tip On / Off Switch Charge Indicator Probe Cap Green / Yellow LEDs Power Jack Flexible Probe High / Low Sensitivity Switch IR Cell Access Door Rubberized Grip Headphone Jack Power Cell Compartment Getting Started The D-TEK Select is shipped with the infrared cell and power stick installed. The nickel/metal hydride batteries in the power stick are not yet charged.
Using Your INFICON D-TEK Select WARNING DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF GASOLINE, NATURAL GAS, PROPANE, OR IN OTHER COMBUSTIVE ATMOSPHERES. Using the D-TEK Select is simple. Press the power switch once to turn the detector ON. The green ON indicator lamp will illuminate, and the yellow indicator lamps will illuminate from left to right in a running fashion while the infrared cell warms up (approximately 60 seconds).
4. When the D-TEK Select signals a leak, pull the probe away from the leak for a moment, then bring it back to pinpoint the location. 5. If the concentration of the refrigerant gas is high, press the sensitivity switch to change to the LOW sensitivity setting. The LOW sensitivity setting helps find the exact site when a leak is large. 6. Once you have isolated the leak source, return the sensitivity setting to HIGH to continue using the D-TEK Select.
WARNING DO NOT ATTACH ANY OTHER POWER CORDS TO THE 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. The D-TEK Select will operate off the AC power adapter. Connecting the supplied AC power adapter will allow operation of the detector while the power stick charges.
Changing the Infrared Cell WARNING COMPONENTS MAY BE HOT. TURN OFF DETECTOR AND DISCONNECT POWER ADAPTER CORD BEFORE REMOVING THE INFRARED CELL DOOR. The D-TEK Select’s infrared cell (IR cell) is located in the body of the detector. The IR cell is a complete assembly consisting of a metal tube, connectors and electronic components. The IR cell is not designed to be taken apart. Doing so will destroy the cell. This specialized IR cell will operate for about 800 hours.
NOTE: If the D-TEK Select does not power up after the power stick is replaced, check that the key connector on the power stick is mated properly to the connector on the circuit board. Reverse the connection if necessary and power up again. If the Hi/Lo indicators flash in a rapid, alternating manner when the AC adapter is connected, the power stick is installed backwards.
