Operating Instructions
AccuProbe UV
1.
POWER ON: The detector is turned ON and
OFF by pressing the POWER button (see figure
1 below).
2.
WARM-UP: The detector automatically starts
heating the sensor to condition it for use. While
in this WARM UP phase – and until ready – the
instrument will signal audibly by beeping slowly
and visually by flashing the sensitivity LEDs
and the zero (0) in the SmartAlarm™ display
window. Warm up time is usually about 20
SECONDS or less. For maximum sensitivity,
wait an additional two minutes after normal
warm-up.
3.
SEARCH: The detector is ready for leak search-
ing when the sensitivity LEDs stop flashing and
the beep rate increases. At this time the zero in
the display window stops flashing. When a leak
is detected, the beeping sound and flashing LED
in the probe will increase in frequency, and the
SmartAlarm digital LED display will turn on
indicating the leak size. If no leak is detected go
to HI sensitivity and continue searching.
SmartAlarm™ Display
The SmartAlarm LED Display is a digital leak size
indicator that numerically displays the leak size on a
scale of 1 to 9 for all HFC and HCFC refrigerants –
regardless of the sensitivity setting. This value helps
you decide whether or not the leak is large enough to
require repair.
For example, when in the HI sensitivity mode, the
detector may sound a full audio alarm but the SmartA-
larm Display may show a low number – indicating
that the leak is very small. In contrast, when in the LO
sensitivity mode, a full audio alarm may not sound but
the SmartAlarm may show a high number, indicating
that the leak is large.

The maximum value displayed, once the source of
the leak is located, indicates the leak size. This value
helps you decide whether or not a leak is large
enough to require repair. The table above shows the
leak rates corresponding to the SmartAlarm numeri-
cal display.
EMITS ULTRAVIOLET RADIATION
Before leak checking with the UV light:
(a) Make sure the A/C system is properly charged
with sufficient dye (see manufacturer's specifi-
cations for proper dye charge.)
(b) Run the A/C system long enough to thoroughly
mix and circulate the dye with the refrigerant
and lubricating oil.

UV LIGHT OPERATION
CAUTION:
This UV LED during operation
radiates UV light
Avoid direct eye and skin exposure
to UV light
If viewing the UV light is necessary,
please use UV filtered glasses to
avoid damage by the UV light
Turn on UV light by pressing the UV light
ON/OFF button (see diagram on left).
Holding the leak detector approximately 10" to
14" away, shine the UV light beam slowly
over the components, hoses, and metal lines
that make up the A/C system.
When the UV light shines on the fluorescent
dye that has escaped from the system, the dye
will glow a bright yellow green.
The UV LEDs will automatically turn off after
five minutes.
