What are the key operating points for driving during dual-idle speed testing?

[DelRowan]

Dual-idle speed testing should avoid direct sunlight or humid environments. Key operating points for dual-idle speed testing: Avoid splashing water, chemical solvents, benzene, or gasoline onto the equipment; prevent the equipment from experiencing impacts and vibrations, perform regular maintenance, and ensure the instrument does not inhale water vapor; connections between external devices such as communication data cables and printers and this instrument must be made under power-off conditions for both sides—never perform hot-plugging; if the equipment's fuse burns out, it must be replaced with an identical model; during equipment calibration, standard gas must be used to ensure measurement accuracy; the vehicle's exhaust system must not have any leaks; do not arbitrarily turn off the power during diagnostic testing or idle speed testing; after obtaining test results, the probe must be removed and the tachometer probe detached before driving; avoid direct sunlight or humid environments. Testing equipment: Exhaust gas analyzer, flow analyzer, tachometer analyzer, OBD diagnostic tool.
