PART 4 – CALIBRATING THE KDM-8206
Figure 4 Front View of KDM-8206 Measuring Module
4.1 Calibration Controls
There are 6 controls to calibrate the KDM-8206, all located on the front panel and accessible by the
narrow end of an adjustment tool. The controls are: Coarse & Fine MIN, Coarse & Fine MID, Coarse
& Fine MAX. The terms MIN, MID, and MAX refer to which part of the measuring range that the
control is intended to adjust.
Coarse controls give a large change in output and are always adjusted first. Fine controls give a
smaller change in output and are used in final adjustments when the difference between actual and
desired voltage is 100 mV (0.1 mA for current calibration) or less. Actual sensitivity of the fine
controls will vary with sensor type.
The calibration controls have been relabeled from previous versions of Kaman products. Instead of
Offset, Gain and Linearity, the terms MIN, MID, and MAX are used to be more descriptive of where in
the normal displacement range they are adjusted
.
4.1.1 MIN Controls
The Min Controls (Coarse & Fine) set the electrical zero point. This control is also referred to as the
“electrical offset”. As illustrated in the diagram below, the Min controls adjust the point at which
output intercepts the x-axis.
