Question
Why do professional diagnostic tools require annual calibration?
Answer
To maintain measurement accuracy (e.g., voltage, current) and update protocol libraries for new vehicles.
Explain
Over time, tool hardware (e.g., multimeter inputs) drifts—CHEPQ’s annual calibration verifies voltage accuracy (±0.1V for 12V systems) and updates protocols (e.g., adding DoIP support for 2024-model vehicles). Calibrated tools avoid misdiagnosis (e.g., mistaking 11.8V for a dead battery when it’s actually 12.1V).
