Hardware Descriptions
Purge Vent Hose
The purge vent hose is a 6-foot length of neoprene tubing with a connector on one end to
mate with the purge vent port. The hose is used to direct venting refrigerant vapor and air
contamination away from the instrument and the ambient air inlet port. This process
ensures no calibration errors or faults occur during purging procedures.
R-134a Tank Adapter Fitting
The R-134a tank adapter fitting provides the user with an adapter to allow connection of
the R-134a sample hose service end to an R-134a cylinder ACME port.
Control Panel
The control panel contains all the user interfaces to permit operation of the instrument:
Digital Display
A 2-line, 16-character, alphanumeric display is provided to inform the user of system
status, required actions, and prompts for specific inputs.
Pushbutton Switches
Two switches, labeled “A” and “B”, are provided for various functions. All inputs from
the user to the instrument are made using these switches. Use of the switches is de-
tailed on the instrument display.
LED Status Indicator Lamps
Red and green LEDs are provided to inform the user of system status at a glance or to
alert the user of required actions or conditions. The LEDs serve dual functions, de-
pending upon the instrument function:
• During refrigerant identification functions, as indicated by the IDENTIFIER FUNC-
TION on the LED label, the green LED indicates refrigerant purity. The red LED
indicates refrigerant contamination or system faults.
• During air purging functions, as indicated by the AIR RADICATOR FUNCTION on
the LED label, the green LED indicates purge completion, and the red LED indicates
system fault.
Storage Case
The instrument is supplied with a portable, corrugated, storage case. The case houses the
instrument, the operating manual, and all associated accessories.
