2.5 Meter Optimisation
Pull up/Pull down ResistorsLink
The pulse meters that Fuellox utilises are based on reed switches and hall effect.
Lower cost meters tend to be Reed Based and more expensive meters tend to be Hall Effect or a combination of Hall Effect and Reed.
Fuellox has been designed with digital logic gates and contains "pins" that need to be correctly set for optimum pulse meter operation. Certain combinations of the pull up and pull down resistors can improve meter performance. If expected results are not sufficient, implement a combination to reach the desired result.

Overview of Meter TypesLink
Reed SwitchLink
If odd behavior is detected or low quality signal/noise from the meter output, a combination of pullup and pulldown resistors can be used. This can enhance the performance of the switch in question. A standard configuration can be found on the standard wiring guide

Hall effect sensorLink
The Pullup and Pulldown resistors can interfere with the Hall effect process, and small changes may be required to reach peak performance of the sensor. This can be done by implementing a combination of pull up and pull down resistors to reach the desired results.
