This shows the analog output voltages versus Lambda for one of the two
analog outputs. The graph display is automatically scaled to the selected
voltages. For each output you can specify a minimum and maximum lambda
or A/F ratio value and the associated voltages.
By selecting the ‘use Air-Fuel-Ratio’ button you can program the curve by
AFR instead of Lambda. This does not change the programming, only the
unit of measure displayed.
Click the ‘Program’ button to upload the new programming data into the
LC-2. Once the unit is programmed the ‘Program’ button will grey out.
Factory Programmed Defaults:
Analog Output 1 is programmed to output between 0 V for an AFR of 7.35
(gasoline) and 5.0V for an AFR of 22.39. Analog Output 2 is 1.1 V for an
AFR of 14 and .1 V for an AFR of 15. Other settings, of course, are easily
programmable between the minimum and maximum range specified earlier.
Avoid connecting or disconnecting any of the serial ports labeled
IN or OUT while the unit is powered ON.
5.2.2 Advanced output

The ‘Advanced’ button allows the
user to set the analog out update
speed and the voltage output
during sensor Warm-up and Error
