WARNING

This symbol alerts the user to the presence of important operating and

maintenance (servicing) instructions.

WARNING

Exposure to high concentrations of CO2 or refrigerants is dangerous and

can be life-threatening.

The instrument is not for use in toxic or hazardous environments. It is not a personal

protection or life-saving device. Always exercise extreme caution in potentially toxic or

hazardous environments.

WARNING

This product is not intrinsically safe and should not be used in the

4 Charging the Battery

D-TEK 3 uses a rechargeable lithium ion battery that comes partially charged. INFICON

recommends charging the battery before use. Using the supplied charger or charging

cradle accessory, a dead battery can be charged to 80% in approximately 2 hours and

100% in approximately 3 hours. A full charge typically lasts about 9 hours of operation,

depending on the operating temperature. The power indicator indicates the remaining

battery percentage.

Color % Charge

Green >30%

Orange 10–29%

Red <10%

D-TEK 3 can be used while charging.

INFICON Turning On the Instrument and Preparing for Use | 5

074-710-P16B D-TEK 3 Operating Manual 9 / 260

5 Turning On the Instrument and

Preparing for Use

If the unit does not turn on, the battery is low and needs to be charged. D-TEK 3 can

be used while charging.

1Long press the power button (located on the left side of the body of the

instrument) to turn D-TEK 3 On or Off.

ðD-TEK 3 begins a variable-time warm-up for 45 to 90 seconds. When warm-

up is complete, D-TEK 3 is ready to use.

2To switch modes, press the MODE button. This toggles between Pinpoint and

Manual Zero modes.

D-TEK 3 always starts in the last mode that was used.

6 Pinpoint Mode

1Place the tip of D-TEK 3 as close as possible to the suspected leak (do not

block the air flow).

2Slowly move the probe past each possible leak point.

ðIf a leak is detected, D-TEK 3 alarms and the leak indicators illuminate.

3When a leak is identified, pull the probe away from the leak for a few seconds

and then recheck the spot to verify the leak.

In Pinpoint mode, D-TEK 3 automatically zeros to the background refrigerant

concentration and only alarms again with a higher concentration of refrigerant. When

this occurs, either continue looking for a higher concentration of refrigerant or move

the probe to an area of lower concentration for a few seconds to reset the zero point.

Press the SENS/ZERO button to switch the sensitivity setting. When working with a

large leak, it can be easier to pinpoint the leak location using a lower sensitivity

setting. The current sensitivity is displayed by the sensitivity (SENS) indicator.

7 | Manual Zero Mode INFICON

10 / 260 074-710-P16B D-TEK 3 Operating Manual

7 Manual Zero Mode

Manual Zero mode operates similar to Pinpoint mode, but is identified by the MODE

indicator slowly flashing. Manual Zero mode allows the user to manually zero to the

background refrigerant by pressing the SENS/ZERO button. Once the new zero point is

set, D-TEK 3 will not alarm unless a higher concentration of refrigerant is detected.

Manual Zero mode beeps faster at the zero point than other modes. If the

concentration is lower than the current zero point, the beeping slows. This allows the

user to know if they are moving away from the leak by listening to a change in the beep

rate.

There is no sensitivity setting in Manual Zero mode.

Manual Zero mode requires an extra warm-up time of up to 15 minutes for optimal

performance.

8 Earbuds and Volume Control

A headphone jack is located on the right side of D-TEK 3 for listening to the alarm

sounds through headphones or earbuds.

WARNING

If attempting to use headphones not supplied by INFICON, be sure to test

them carefully to avoid hearing damage.

A volume button is located next to the headphone jack. Press the volume button to

toggle from 100% volume, to 50% volume, and to mute. The volume defaults to 100%

at startup. When headphones or earbuds are plugged in, the volume toggles between

100% volume and mute.
