Maintenance
5.1 Routine Maintenance
The Model 2750 Turbine Generator Gas Analyzer is a rugged
instrument and needs little maintenance. Routine maintenance is limited
to instrument cleaning, periodic calibration and leak checking. If any part
of the instrument malfunctions or fails to perform, the unit should be
removed from service and returned for repair and calibration. The 2750
contains no user-serviceable parts.
5.1.1 Instrument Cleaning
Use a damp cloth to wipe the instrument clean. Do not use abrasive
cleansers or solvents especially on the LCD. Do not store the instrument
with the case open and in direct sunlight.
5.1.2 Periodic Calibration
The Model 2750 will require periodic calibration; the frequency
will depend on the user’s application and frequency of use. It is a good
idea to verify the zero each time the unit is used. If the zero has drifted
then perform both a zero and span calibration on all ranges. Refer to
Section 3.3 for calibration procedures.
5.1.3 Leak Checking
CAUTION: HYDROGEN IS A FLAMMABLE AND EXPLOSIVE
GAS. NEVER USE A FLAME TO CHECK FOR LEAKS.
CAUTION: DO NOT PERFORM LEAK CHECKING OR ANALYSIS
IN AN AREA WHERE EXPOSED FLAMES OR
IGNITION SOURCES ARE PRESENT
CAUTION: WHEN USING HYDROGEN GAS OR HYDROGEN GAS
MIXTURES, MAKE SURE THE GAS EXITING THE
UNIT IS VENTED PROPERLY.
