6.0 Maintenance & Troubleshooting

There are no general maintenance requirements for the Model 730 other than

periodic zero adjustment. If the unit fails to operate when received or if the

unit appears damaged, notify Setra Systems or your supplier immediately.

Retain packaging materials for inspection. Do not use if damaged. If the Model

730 is not going to be used immediately then replace the protective ﬂange

cover and store in suitable conditions described in Section 2.

If no obvious damage has occurred, a few simple checks can be made to verify

proper installation. Table 2 shows the solution to common problems with the

installation. If none of these problems/solutions are applicable, then please

contact a Setra Systems applications engineer for further assistance.
