Hardware Descriptions
HARDWARE
The instrument houses the following basic components required to
operate the Identifier:
1. Case: An injection-molded plastic housing that contains all internal
components.
2. Hanger: Connects into the top of the case and provides the user a
means to hang the instrument above the working area for hands-
free operation.
3. Sample Filter: Filters oil mists and particulate from the sample gas
admitted into the instrument to provide trouble-free function of the
detection and sampling components.
4. Control Panel: Consists of a two-line, 16-character, digital
display and two pushbutton switches. The display conveys
analysis results and instructions to the user. The switches provide
a means by which the user can communicate with the instrument
microprocessor during use.
5. Air Intake Port: Admits fresh air into the sampling system to
permit calibration of the infrared and chemical fuel cell detection
devices. Do NOT block or restrict the port hole during use of the
instrument.
6. Sample Exhaust Port: Emits sample gas that has been analyzed
by the instrument. Do NOT block or restrict this port during use of
the instrument.
7. Sample Inlet Port: Permits the connection of either an R-12 or
R-134a sample hose to the instrument.
