Checklist for Basic Troubleshooting
This troubleshooting section addresses the problems that commonly arise out
of misapplication of the procedures in this manual, simple oversight, or
changing environmental conditions. Understanding of the material outlined in
this manual and a common-sense approach to system use will preclude most of
the problems listed below from happening.
Approximately 98% of potential difficulties can be prevented or eliminated by
going over the following checklist:
If you have absolutely no output from your system, there is a good chance
that there is no power supply voltage.
•
Check your power supply for ± 15 VDC. If you have provided your own
power supply, make sure it is capable of supplying the minimum current to
operate the system.
•
Check loose plugs.
•
Make sure the power switch is on.
•
Check for a malfunctioning voltmeter.
After ensuring that you have a correct and reliable power feed:
•
Check the security of connectors.
Incorrect calibration procedures can cause problems:
•
Follow the calibration procedures in this manual closely.
•
A calibration span that is too large or too small, incorrect offset, or gross mis-
adjustments of the calibration controls can cause drift, erroneous output, or
make it impossible to calibrate.
•
Extremely high or low sensitivity/gain can cause drift and make the system
overly sensitive to temperature variations, target size, etc.
