3.3 4-20 mA Current Output:
For industrial applications or long output cable lengths, a 4–20 mA current output may be used. For
current output, connect the – lead to terminal 2 and + lead to terminal 6 as shown. The loop is
powered by the KD-2306.
NOTE ABOUT CURRENT OUTPUT: Early versions of the KD-2306 (i.e. serial numbers beginning
with “S08”) require a separate loop supply. The loop supply must have adequate voltage to deliver
20 mA to the load. If the voltage is too low for the load resistance, 20 mA will not be achieved.
Part 4 - Calibrating the KD-2306
4.1 Calibration Controls
There are 6 controls to calibrate the KD-2306, all located on the front panel and accessible by the
narrow end of an adjustment tool. The controls are: Coarse & Fine Linearity, Coarse & Fine Gain,
Coarse & Fine Zero. Coarse controls will give you a large change in adjustment; Fine controls will
give you a smaller change in output and are used in final adjustments.
The calibration controls have been relabeled in newer versions of the KD-2306. Instead of Offset,
Gain and Linearity, the terms MIN, MID, and MAX are used to be more descriptive of their functions
(i.e. effect on calibration curve)
