IMPORTANT
: The instrument’s software is designed to alert the
user if the sensor is dislodged or defective. If the sensor is not fully
inserted into the six-pin socket, or if it is defective, the instrument
will not come out of the “Warm Up” mode for proper operation when
the power button is turned on. Additionally, if the instrument
becomes unstable during its operation, it is an indication that the
sensor may be defective or dislodged.

3. WARM UP
: The detector automatically starts heating the sensor. During
the heating cycle the detector will sound a slow “beep”. Warm up is
usually less than 20 seconds.
4. READY
: The detector is ready to begin searching for leaks when the green
sensitivity LED turns on and the audio “beep” increases in frequency.
Changing the Sensitivity Levels for (SAEJ2791) and
(SAEJ2913)
The detector has an excellent response to tiny leaks for both R-134a and R-
1234yf. However, the three sensitivity levels for the two refrigerants are
different and require changing in order to comply with SAEJ2971 (R-134a)
and
SAE2913 (R-1234yf).
On power up the detector defaults to the sensitivity levels required for R-
134
automatically
as long as the ON/OFF is released while the low battery indicator
is still on. To set the sensitivity levels required for R-
1235yf on power up, press
and hold down the ON/OFF button slightly longer and releas
e when the low
battery indicator turns off.
