Chapter 6: Maintenance and Troubleshooting
However, because different components heat or cool at different rates, the device
is expected to reach a steady state temperature within a ±3 degree (Celsius)
bandwidth for five minutes before measurements can be taken. For convenience,
the electronics system is programmed to generate an error message when the
temperature exceeds a ±3 degree bandwidth. There is also a built-in routine for
the establishment of temperature stability; whereby, the device monitors itself for
five minutes and indicates to the user that it is ready for use.
Electrostatic Discharge (ESD)
Electrostatic Discharge (ESD) refers to pulses generated by the discharge of
loaded objects and/or people. The charge usually comes from friction between
materials, at least one of which is a nonconductor.
• Although these units are protected against damage by ESD, extra care and
proper ESD procedures still must be observed and followed.
If an error occurs because of ESD, check the Error Message displayed on the
screen and follow the steps below to resume normal operation. If you experience
anything out of normal operation:
1 Turn off the Edge.
2 Wait for at least five seconds before powering the unit on.
This should restore communication with the host computer.
ESD Best Practices
The following is a list of equipment and best practices to avoid ESD events.
Wrist Straps - Wrist straps fit snugly around a person’s wrist and are connected
to an ESD ground point (never earth ground) or to a grounded mat. A poor
connection with a wrist strap is associated with a loose fit or dry skin (use an
ESD lotion for dry skin). A wrist strap may be used if an approved ESD smock is
not available. However, wrist straps do not shield ESD sensitive components
from damage induced by the wearer’s clothing.
Heel Straps - Heel straps should be placed so that they make contact with a
person’s ankle. Static charges are dissipated through the floor by means of a
Conductive Flooring. When seated, heel straps do not offer the protections
required to dissipate a static charge.
ESD Lotion - ESD lotion provides a better connection between the user and a
smock, heel strap or wrist strap. This may need to be reapplied if the smock or
straps are removed.
