CALIBRATION
& UNIT OF MEASURE
The 201-EBT-04(B) load scale must be calibrated both empty and loaded to
work properly. The scale associates the weight you enter with the air
pressure in the suspension system at the time of calibration. You will need to
calibrate once while the vehicle is empty, and again while the vehicle is
loaded for each axle group being monitored.
Only enter on-the-ground weight of axle or group being
monitored. DO NOT use gross weight, tare weight, etc.
CHANGING UNITS
With the gauge on, press and hold the UP ARROW
and then press the MENU button. This will toggle
the settings between pounds and kilograms.
