WARNINGS

To ensure safe operation and service of the tester, follow these
instructions. Failure to observe these warnings can result in severe
injury or death. Know the characteristics of the gas you are working
with and use proper precautions to avoid hazardous conditions.

• Read, understand, and follow all instructions to ensure safe operation.

• Always turn on the gas detector in an area known to be free of gases.

• Initial calibration should be per
refrigerant gases. Calibration in an area containing refrigerant gas will
result in incorrect calibration and lower than actual readings. This could
result in refrigerant gases not being detected.

• The refrigerant gas leak detector is
device (PPE).

• The refrigerant gas leak detector is NOT insulated. Avoid contact with areas
where energized conductive elements may be present. Shut off power to
the area before starting measurements.

• Do NOT probe moving machinery that could catch any part of the meter
and cause harm to the operator and the meter.

OPERATING INSTRUCTIONS

1. In an area where gas is known to be not present, press the

power button

13

for 3 seconds. The tester will beep and start a
50-second zero-calibration process while the first indicator light
(blue)

4

blinks. Once complete, all indicator lights

4 5 6

will blink for one second, then the HIGH indicator light 6 will
illuminate and continue to flash, indicating it is ready to take a
measurement.

2. Start measuring in the High sensitivity mode (100 to 1,000 ppm).
o view higher values (200 to 3,000 ppm), press the LOW button

T

10

to enter Low sensitivity mode.

3. Point the sensor

3

towards the area to test. If all blue indicator
lights are illuminated in High sensitivity mode, switch to Low
sensitivity mode by pressing the LOW button

10

.

NOTE: Changing from High to Low sensitivity mode may cause
some of the indicator lights to turn off.

4. As you get closer to the source of a leak, the concentration levels
detected will increase, as indicated by increasing audible/visual
alarms. Move the sensor head in the direction of increasing
audible/visual alerts to the source of the leak.

WARNING: High concentrations of refrigerant gases can cause
asphyxia and other hazards that could cause serious personal
injury or death. Know the characteristics of the gas you are
working with and use proper precautions to avoid hazardous
conditions.
