Figure 9. Calibration graph of available outputs
To change the calibrations, a precision flat head screwdriver is needed. Locate the small hole located on
the back of the AEM gauge, as shown below. (Figure 10)
Figure 10. Calibration position screw location
With the screwdriver, clock the rotary switch into the desired calibration position, referring to the diagram
below (Figure 10A), and watch the alphanumeric readout, which will display the new position when
