TPS Example:
To calibrate a TPS sensor, connect the sensor to for example an LMA-2 or LMA-3, switch the
ignition on but don’t start the car. Enter % as the unit and enter 0 in the upper box of field 3. Then
right-click on the upper box of field 4. A menu will show up that allows you to paste in the current
voltage of the TPS sensor into the upper box of field 4.
Next enter 100 in the lower box of field 3, depress the gas pedal fully and right-click in the lower
box of field 4. Paste in the full throttle voltage.
Field 6.
Clicking on the “Invert Scale” exchanges the upper and lower boxes of field 3. This is useful for
example for duty-cycle measurement. Normally the LMA-3 will measure positive duty cycle. This
means that 100% duty cycle happens when the input is at full voltage and 0% when the input is a
0Volt. A typical fuel injector and also ignition points show full voltage when off and 0V when on.
This is a negative duty cycle. By inverting the scale you can measure this duty cycle correctly
where 0V means 100% and full voltage means 0%.
Field 9.
Inverts the scale, so the 0V equivalent becomes equivalent to 5V and the 5V equivalent becomes
0V.
Field 10.
Adds or deletes custom lookup tables. See chapter 4.1 for details
Field 11.
Clicking on this button brings up a little calculator box.
This is a convenience to quickly calculate the voltage equivalents (or unit equivalents) for the
current channel configuration.
