7 | Turning On the Instrument and Preparing for Use JAVAC
074-710-P21-B JAVAC D-TEK 3 Operating Manual
7 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.
8 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.
11 / 21

9 | Manual Zero Mode
JAVAC
074-710-P21-B JAVAC D-TEK 3 Operating Manual
9 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.
10 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 JAVAC, 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.

13 | Replacing Filters JAVAC
15 / 21 074-710-P21-B JAVAC D-TEK 3 Operating Manual
13 Replacing Filters
D-TEK 3 uses a hydrophobic filter cartridge that allows air and refrigerants to pass
through while filtering out water, dirt, and oil. Examine the white cloth to determine if
the filter needs to be changed. If the cloth appears discolored, install a new filter.
Changing the filter is also an easy troubleshooting step if you suspect your leak
detector is not properly detecting refrigerants. A clogged air filter can limit the sample
air flow.
probe tip
filter
Exposing the filter to water or oil can block air flow. If this occurs, remove the filter with
the unit turned off and the probe facing down to avoid getting contaminants in the
probe and install a new filter. If the filter is wet, it can be reused once it dries.
CAUTION
Never use the instrument without a probe tip and filter.
To replace the filter:
1Unscrew the probe tip and remove the filter.
2Insert the new filter into the probe.
3Screw the probe tip on. Do not overtighten.

16 Optional Sensors
Optional sensors are available for use in CO2 (PN 724-701-G2) or flammable
refrigerant (PN 724-701-G3) applications. To use the CO2 or flammable refrigerant
sensor, remove the standard sensor and install the new sensor following the
instructions in Removing and Installing the Sensor [}17]. D-TEK 3 automatically
recognizes the sensor type and the MODE indicator illuminates the appropriate color
to indicate the sensor type the entire time the sensor is installed. Green indicates CO2,
red indicates flammable refrigerant, and orange indicates the standard refrigerant
sensor is installed.
If D-TEK 3 does not automatically recognize your flammable refrigerant sensor,
contact JAVAC to arrange a software update.
The flammable refrigerant sensor does not detect hydrogen, including hydrogen
forming gas.
While searching for CO2 leaks, it is recommended to wear a respirator or mask to
avoid exhaling CO2 toward the probe.
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
presence of explosive fumes, explosive dust, or other explosive
chemicals. Use in an environment with flammable refrigerant
