Introduction
General Setup Tips
X
Read and follow the procedures in this manual.
X
Keep the probe tip openings clean and free of debris.
X
Do not place the probe tip in liquids or allow liquids to be drawn
into the analyzer sampling system. Contamination affects the
accuracy of any tests.
X
Do not place the probe in an exhaust pipe until the vehicle is at
normal operating temperature. This allows time for the exhaust
system to vaporize residual moisture.
X
Never move the analyzer by pulling on the probe, sample hose
or power cord.
X
Never drive over the probe, sample hose or power cord.
X
Never set liquids on the analyzer that could spill and run into the
ventilation holes.
X
Clean off any spills, like gasoline, brake fluid, cleaning solvents,
etc., from the exterior of the analyzer immediately to protect the
finish.
X
Always keep the calibration gas bottle valve in the closed
position, except when performing calibration procedure.
X
Perform a Leak Check (vacuum) daily, and also after probe
changes and filter service, to ensure accurate analysis. For
additional information refer to
Chapter 4–Maintenance
.
X
Prolonged use of the analyzer in conjunction with a
dynamometer and a hot-running vehicle under load may
damage the sample probe and affect readings.
X
The O
2
sensor has an average life expectancy of 12–18 months,
regardless of how often the analyzer is used.
X
The NO sensor has an average life of 15–18 months after
installation. It is powered by an internal battery in the analyzer.
The analyzer must run for at least 12 hours over a 30 day period
to maintain this battery at full charge.
