Introduction
The MoTeC Professional Lambda Meter measures Lambda (or Air Fuel Ratio) 
over a wide range of mixtures with fast response time. 
The display may be set to Show Lambda, Air Fuel Ratio (for Petrol, Alcohol, 
Gas, Diesel or ‘blend’ fuel), equivalence ratio or percentage oxygen. 
The PLM provides a differential Analog Output Voltage proportional to Lambda 
that may be connected to an Analog Meter or other measurement instrument 
such as an ECU, Data Logger or dynamometer. 
The PLM also supports RS232 and CAN data links to devices such as the 
Motec Dash Logger or M800 ECU for transmission of sensor and diagnostic 
data. 
This manual covers the configuration and operation of the meter.
