9.4 Troubleshooting the DF–745 NanoTrace Analyzer

The DF-700 series moisture analyzer constantly performs internal monitoring of the analyzer

operation. In the event of a failure a system alarm will be displayed on the front panel. In

addition the failure will be logged in the System Error Log (see page 47). In the event of a

system alarm contact Delta F with information as displayed in the log as well as on the Signal

Monitor screen as shown on page 60.

Shipping

If it is necessary to return the analyzer to the factory or ship it to another location, follow the

packaging and shipping procedure below in order to prevent damage to the analyzer during

shipment.

1. Isolate the analyzer gas path properly by following the steps on page 37.

2. Turn off the power switch. Disconnect any source of AC power from the analyzer.

etc.).

4. Mark each for reattachment later.

original container.
