Changing the Maximum Scale Value, Continued:
2) Press the ENTER key, then scroll UP or DOWN to change the Maximum
Scale value. This value determines the maximum RPM, MPH or KM/H value
that will be displayed on the TELEMETRY screen ALL and RPM pages.
MAX SCALE setting range is 500 to 127500 RPM, 1 to 999 MPH and 1 to 999 KM/H. The default setting is 30000 RPM, 34 MPH
and 54 KM/H.
The Maximum Scale MPH and KM/H setting range will vary based on the 10Count Distance value programmed when you
calibrate the RPM Sensor. For more information, see the Calibrating the RPM Sensor - Changing the 10Count Distance
Value section on pages 58 and 59.
Calibrating the RPM Sensor - Changing the Ratio Value:
The Ratio value can be changed if you've selected UNIT > RPM. By changing the Ratio value you are able to read actual motor or
engine RPM even though the RPM sensor may be mounted to your model's spur gear and not to the motor's pinion gear or the
engine's flywheel.
1) From within the RPM menu and with UNIT > RPM Selected, scroll UP or
DOWN to highlight RATIO > 1.000.
The Ratio value is the gear ratio between the two gears that the RPM sensor is mounted to. For example, if the RPM
sensor is mounted to your spur gear, the Ratio value will be the gear ratio of your spur gear and pinion gear.
IMPORTANT: To calculate the gear ratio, divide the number of teeth in the spur gear by the number of teeth in the pinion
gear. For example, if your spur gear is 60T and your pinion gear is 14T, the gear ratio is 60 / 14 = 4.28.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired first Ratio
value. If using the example above, choose 4.
3) Press the ENTER key, then scroll DOWN to highlight the second Ratio
value. Press the ENTER key, then scroll UP or DOWN to choose the desired
second Ratio value. If using the example above, choose 28.
4) If necessary, press the ENTER key, then scroll DOWN to highlight the third
ratio value. Press the ENTER key, then scroll UP or DOWN to choose the
desired third Ratio value.
RATIO setting range is 1.000 to 64.999. The default setting is 1.000.
If the RPM sensor is mounted to your engine's flywheel or your motor's pinion gear to read the RPM directly, the Ratio
value should be set to 1.000.
Calibrating the RPM Sensor - Changing the 10Count Distance Value:
The 10Count Distance value can be changed if you've selected UNIT > MPH or UNIT > KM/H. By changing the 10Count Distance
value you are able to calibrate the RPM sensor to read your model's actual speed, in either MPH or KM/H.
