Overview
The working principle of the calibration device H1.0 for OBD diagnostic instrument: $r $n uses a handheld computer as a carrier to simulate various data and codes generated during engine operation, and sends relevant information to the OBD diagnostic instrument through a communication device, including CVN, CAL ID code, fault code, ready status, data flow, etc. The returned data of the OBD diagnostic instrument is compared and verified with the sent data to confirm whether the OBD diagnostic instrument meets the relevant technical standard requirements (especially the communication protocol).
Product Details
OBD diagnostic instrument calibration deviceWorking principle of H1.0:
OBD diagnostic instrument calibration deviceUsing a handheld computer as a carrier, simulate various data and codes generated during engine operation, send relevant information to the OBD diagnostic instrument through a communication device, including CVN, CAL ID codes, fault codes, readiness status, data flow, etc., and compare and verify the returned data of the OBD diagnostic instrument with the sent data to confirm whether the OBD diagnostic instrument meets the relevant technical standard requirements (especially the communication protocol).
Main functions:
1. Protocol comparison: Compare according to various communication protocols specified in HJ1237
2. Information comparison: Verification of the CVN and CAL ID code functions read by the OBD diagnostic instrument
3. Fault code comparison: Verification of OBD diagnostic instrument's fault code reading function
4. Ready state comparison: Function verification of OBD diagnostic instrument reading post-processing device related information
5. Data flow comparison: Verify the reading function of the OBD diagnostic instrument for engine data such as engine speed, throttle opening, nitrogen and oxygen sensor concentration, etc
6. IUPR comparison: functional verification of OBD diagnostic instrument reading sensor related information
7. Freeze frame data comparison: Verify the function of the OBD diagnostic instrument to read environmental data during engine faults
