Refrigerant Identification Operational Procedure

1. Plug the power cord of the instrument into a suitable receptacle. Various parameters of

the instrument are displayed and the warm-up period begins.

2. The warm-up period lasts for 90 seconds. The display reads SYSTEM WARMING-

CHECK FILTER, which is a reminder to inspect the instrument's sample filter.

3. During the warm-up period, it is possible to print the results of the last refrigerant

identification run made prior to power-up of the instrument. To print the prior results,

connect a user-supplied cable and printer to the instrument printer port, and press the

“A” button. The prior results are downloaded to the printer.

4. During the warm-up period, enter the local elevation above sea level into the instru-

ment memory. The instrument is sensitive to elevation changes of 500 feet (152

meters), and the local elevation must be entered into the instrument memory upon

initial use. After the local elevation has been entered into the instrument memory, there

is no need to enter it again unless the instrument is moved to a new elevation. To enter

the elevation into the instrument memory, follow the procedure presented by the

instrument display.

a. During the warm-up period, depress and hold the “A” and “B” buttons simulta-

neously until the display reads USAGE ELEVATION, 400 FEET. This is the factory

setting of 400 ft. (122 meters) elevation.

Use the “A” and “B” buttons to adjust the elevation to the nearest 100-foot (30-meter)

increment. Pushing the “A” button increases the elevation setting by 100-ft. incre-

ments. Pressing the “B” button decreases the elevation setting by 100-ft. increments.

The setting is adjustable from 0–9000 feet (0–2743 meters) and is displayed while

adjusting.
