Operation
Power
Press >1 second to toggle power.
Backlight
Press to toggle the blue backlight.
Zero Modes (AZERO/MZERO)
DR82 starts up in automatic zero mode
(AZERO) which sets a new zero point every 4-5
seconds, indicated by a double beep.
Moving closer to the leak source will show the
relative increase in concentration, triggering the
alarm. Conversely, stopping at or moving away
from the leak source will not trigger a response.
Press MANUAL/AUTO >1 second to toggle
manual zero mode (MZERO). DR82 does not
zero automatically while MZERO is displayed
and will continue to alarm and display the
relative leak size.
Zero Set
In manual zero mode (MZERO), press ZERO to
initiate a 10 second calibration, during which
"Zeroing" is displayed. For best performance,
remain stationary until calibration nishes.
Numerical Leak Size Indicator
with Bar Graph
The number is the relative concentration of
refrigerant gas (0-99 units). The bar graph shows
the same measurement in steps of 10 units for
easy monitoring. The higher the number, the
higher the concentration of gas being measured
and the closer you are to the exact leak location.
Maximum Mode
Press MAX ON/OFF >1 second to toggle max
mode. When max mode is on, the highest leak
size detected is continually recorded.
The recorded max is cleared when the
sensitivity is changed or if manually zeroed.
Sensitivity (H/M/L/T)
DR82 starts up in high sensitivity (H) which is
recommended for most situations. When leaks
are dicult to pinpoint due to excess triggering
or sensor saturation, press SENSITIVITY to cycle to
another sensitivity (Medium/Low/Turbo). Turbo
is extremely sensitive, and may false trigger from
abrupt motion or small changes in gas content.
Mute (
)
Press ZERO and SENSITIVITY simultaneously to
toggle the speaker.
Red Leak Indicator LED
In most situations, the red LED at the tip is
easier to monitor than the display. Because the
blink rate increases as the relative concentration
increases, many leaks can be found without ever
viewing the display.
