1. Turning D-TEK Stratus on and preparing for use
a. Long-press the power button to turn D-TEK Stratus on or off.
NOTE:
If the screen does not turn on, the battery is very low
and needs to be charged. D-TEK Stratus can be used
while charging.
b. D-TEK Stratus will begin a warm-up for 45 to 90 seconds. When
warm-up is complete, D-TEK Stratus is ready for use.
c. To switch modes, press the MODE button. This toggles between
Cloud Hunting, Pinpoint and Manual Zero modes.
NOTE:
D-TEK Stratus always starts up in the last mode that
was used.
2. Using Cloud Hunting (Portable Monitor) mode
a. Slowly move through the suspect areas and observe the ppm reading.
b. Follow the ppm reading to find areas of higher refrigerant
concentration. The higher the number, the higher the concentration
of refrigerant and the closer you are to the leak source.
NOTE:
Lingering in an area with refrigerant for several minutes
may cause the ppm reading to decrease. If this occurs,
move to an area of lower concentration for a few seconds.
c. Press the SENS/ZERO button to enable/disable the MAX
feature. When enabled, the highest ppm level observed is
shown below the main ppm display. To reset the max reading,
long-press the SENS/ZERO button.
NOTE:
There is no sensitivity setting in Cloud Hunting mode.
3. Using Pinpoint mode
a. Place the tip of D-TEK Stratus as close as possible to the
suspected leak. Do not block the air flow.
b. Slowly (2.5 to 5 cm [1 to 2 in.] per second) move the probe past
each possible leak point. If a leak is detected, D-TEK Stratus will
alarm and the on-screen indicators will illuminate.
NOTE:
In Pinpoint mode, D-TEK Stratus will automatically
zero to the background refrigerant after a few seconds.
