Desiccant Replacement
The EpiSensor contains a small package of desiccant that is designed to
maintain a low humidity level inside the unit. If the case is open for a long
period of time, opened repeatedly for inspection or adjustment, or in very
humid conditions, the desiccant may be incapable of absorbing more
moisture. This is shown by the ink on the desiccant pack turning from its
original blue to pink. When this happens it should be replaced.
New desiccant can be ordered from Kinemetrics as P/N 700403. Be sure to
follow electro-static discharge (ESD) precautions when the sensor case is
opened.
Instructions for opening and closing the EpiSensor case are provided in
Chapter 3.
Caution:
Potential electrostatic discharge (ESD) hazard to equipment
.
Wear a grounded wrist strap with impedance of approximately 1 M
%
when
handling the EpiSensor circuit boards to protect components from damage.
Troubleshooting and Repair
If your EpiSensor does not appear to be working, we suggest you first check
that the cabling and power supply are correct. If the problem persists we
recommend you return the unit to Kinemetrics for repair and re-calibration.
