The 3400-B series utilizes a high degree of integrated circuit
technology. For this reason the reliability level is very high and
repair is relatively simple because it consists of module or PC
Board replacement.
If the gauge will not perform the functions described in the
operating procedures, refer to the Troubleshooting section
(starting on page A-7) or contact a Troxler representative.
If all the gauge functions perform normally but readings are
suspect, perform stability and drift tests as outlined in the next
section. If the gauge operates normally and is stable but field
density and moisture readings are suspect, refer to the
Troubleshooting section.
