Troubleshooting
ccasionally, you may encounter problems with your LMI
instrument or detector that may be repaired or resolved in the field,
saving turnaround time and expense in returning the instrument to
us for repair. Toward that end, LMI electronic technicians offer the
following tips for troubleshooting the most common problems. Where
several steps are given, perform them in order until the problem is corrected.
Keep in mind that the most common problems encountered with this
particular instrument are: (1) detector cables, (2) sticky meters, and (3) battery
contacts.
Note that the first troubleshooting tip is for determining whether the problem
is with the electronics or with the detector. A Ludlum Model 500 Pulser can
be invaluable at this point, because of its ability to simultaneously check high
voltage, input sensitivity or threshold, and the electronics for proper counting.
We hope these tips will prove to be helpful. As always, please call if you
encounter difficulty in resolving a problem or if you have any questions.
