BDF-1 engine dedicated tachometer calibration device

▲ Function 1. Simulated vehicle ignition state and the stable and accurate output of the ignition signal generating source, and according to the number of the selected cylinder and stroke ratio, the output speed to adapt the speed range of the output of the unit covering all the scale range of 2 checklist. Any keyboard input speed value. Certain procedures can also be scanned, sufficient residence time of 3 test at each speed points. Set 8-speed pulses Pulse / R select 4. Set the frequency output port, the frequency of Origin. ▲ Performance 1. Ignition signal range (corresponding speed value): 10 ~ 20000 r / min 2. Resolution: 1 r / min 3. Reference frequency accuracy: 1 × 10-5 4. ignition signal accuracy: 2 × 5. The ignition signal stability 10-5: 2 × 10-5 6. Select the number of pulses per revolution Pulse / R (the number of cylinders and the number of strokes and was seized table corresponding to the selected) tranche of a total of 8: 1/2 1, 3/2, 2, 5/2, 3, 4, 6, 7. Automatic scan rate: every 15 seconds 8. Total value of staying power: 40W ▲ apply to be examined in Table 1. Gasoline engine induction tachometer as: SE-1100 (Japan Ono), TES-1550 (Taiwan), HZJ-1100 (Shanghai), STK250 (Korea) 2. Cars with three tables (speed function) such as: UT106 (Hong Kong) DY220 (Shenzhen)
