Using the arrows, select the temperature; when the "gun" reads that temperature, press
Select
:
Repeat this up to 10 times. You should try to get a pretty nice distribution of temperatures from
the expected lowest to expected highest temperature.
Temperature channels can have alarms associated with them. See the section on Alarms.

Gear
Gear
Vehicles that have a gear sensor (e.g., many fuel-injected motorcycles) have a gear sensor which
can be used to determine gear. This type of sensor provides an analog voltage output which is
different for each gear. To calibrate this input, you must first enter, in the menu system, the
number of gears the vehicle has (not including neutral). Then you are prompted to put the
vehicle in each gear, and neutral. This completes the calibration. The data acquisition system will
then record this input as N (neutral), or 1-6 (for example, for a 6-gear bike).
There is an alternate method of capturing and calibrating gear data if a gear sensor is not present.
You must be connected and picking up RPM data (although you do not need to capture it if you
don’t want) in order for this method to work. For this calibration, you need to drive/ride the
vehicle in each gear, and when you are going smoothly and straight ahead in each gear, press the
Select button. (This records the relationship between speed and engine RPM to determine a final
drive ratio.) It is important that the tires are not slipping.
