instrument can be used to detect Refrigerant. When the

sensor in the probe tip detects a Refrigerant, the tic rate

will increase, and the instrument sounds a warbling tone

while the ALARM light is lit. As the concentration of gas

increases so does the tic rate.

If the situation calls for quiet operation, or if background

noise makes it difficult to hear the built-in speaker, you can

use an earphone. The jack is at the top of the instrument.

Note that listening to the alarm or tic through the

earphone is very loud.

If the READY light is off, the batteries are low. They should

be replaced immediately. Low batteries will adversely

affect the instrument's reliability. See the replacement

procedures.

Adjusting the Tic Rate (Sensitivity)

The tic rate tells you when the sensor (in the tip of the

instrument) is getting close to Leak Refrigerant. You can

control the tic rate using the rotary wheel in the center of

the instrument.

• Move the wheel clockwise to increase the frequency

• Move the wheel counterclockwise to decrease the

frequency

As the sensor comes near a Refrigerant source, the tic rate

increases. In order to isolate the source of a leak, you may
