How does a Smiths Chronometric Speedo work?
Chronometric tachometers and speedometers contain clock mechanisms with balance wheel movements. These movements are cleverly driven by the rotating input cable through a slipping clutch. A three lobe camshaft, whose rotation is driven by the clock, serves as a ‘mechanical director’.
What is a Chronometric speedometer?
The Chronometric speedometer is a principle commenced by the Jaeger speedometer company in Paris, France, in the 1920s and as such is a METRIC instrument, that is the dimensions, screws, threads etc are metric and not imperial as generally thought.
How does a Smiths speedometer work?
The speedometer (speed indicator, not odometer) functions in just the same way as a tachometer. The cable spins a thin bar magnet. Just in front of the bar magnet is a disk mounted on a spindle. Also attached to this, on the same spindle, is the pointer that is visible over the dial face.
What is Chronometric time?
Chronometry (from Greek χρόνος chronos, “time” and μέτρον metron, “measure”) is the science of the measurement of time, or timekeeping. It should not to be confused with chronology, the science of locating events in time, which often relies upon it.
How do you calibrate a Smith Speedo?
The calibration mode is selected by switching on the ignition while simultaneously pressing the trip reset button. The pointer will travel to full scale and return to zero. If the button is released after the pointer returns to zero the ‘drive to set’ mode is selected and the LCD will show ‘DTS PPU. ‘
Is Chronometric dating Seriation?
Seriation is the ordering of objects according to their age. It is a relative dating method. In a landmark study, archaeologist James Ford used seriation to determine the chronological order of American Indian pottery styles in the Mississippi Valley.
What is Chronometric analysis?
a method for studying a mental process that involves varying stimulus input conditions and measuring participants’ reaction times to those stimuli. The relations between the stimulus variables and reaction times are then used to make inferences about the underlying mental processes.
How do I change my speedometer reading?
Press and hold the calibration button located on the speedometer, start the vehicle, and then release the button. Press that button again and then take the test drive. Once you have driven the distance needed, press the button once more and the speedometer will calibrate itself to accommodate the new tire size.
Can speedometer be calibrated?
A speedometer calibration is performed by mechanics and it’s a procedure that measures the accuracy of your vehicle’s speedometer. The mechanics test whether the speedometer is properly calibrated. The procedure comes with a report showing whether the speedometer was off and if so, by how many miles per hour.
