KD-2300 Instruction Manual Appendix C: Troubleshooting •

••

• 39

Problems with sensor mounting and nonrepeatable fixturing can be

sources of trouble:

• Make sure your calibration fixture is sound and repeatable.

• When you move the sensor from the calibration fixture to the

application fixture, maintain the offset.

• Make every effort to provide a thermally stable environment to prevent

drift. (Kaman can provide temperature compensation, but your best

choice is to control the environment if possible).

Inappropriate target materials can also lead to difficulty using the

system:

• When you calibrate, use actual target materials in the same sizes.

• Whenever possible use the actual application environment or simulate it

as closely as possible.

Do not make any arbitrary changes in sensor/cable and

measurement module combinations

Symptoms and Causes

The following information is a Symptom/Solution cross reference. If after

reviewing the previous checklist of common problems you don’t remedy the

problem you are having, find the symptom you are experiencing below and

refer to the list of possible causes. Symptoms are marked with letters;

causes/solutions are marked with numbers. For example, if you are

experiencing the symptoms described in C, refer to solution 3.

SYMPTOMS

A. A saturated output of +/- 6 to 7 volts, with no change in target position and

with target in range. See 2 (open only) and 3,5,6.

B. Unchanging output voltage, anywhere from +1 to -2, with change in target

position. See 2 (short only) and 3, 5, 6.

C. Output drifts with no change in target position. See 3.

D. Random changes in output with no change in target position. See 1, 3, 4, 5, 7

(for multiple channel system) and 8.

E. Non-repeatability. See 3, 4, 6, 7, 8.

F. Unable to calibrate, or while calibrating you ‘run out’ of calibration controls.

See 1, 2, 3, 5, 6, 8.

G. System does not meet linearity specification. See 3.
