4.4 Interface Connector Cleaning

WARNING

Always turn the 35360A TRACKER Display's power off prior to cleaning the interface connectors. Failure to do so may result in an electrical shock.

The presence of dust or lint at the interface connectors can produce leakage currents which may have a detrimental affect upon the accuracy of radiation measurements.

The ends of the interface cable typically pick up dust and lint as the cable touches the floor during packing and unpacking. Dirt may later be transferred to the interface connectors located on the 35300A Detector or on the 35360A TRACKER Display during mating with the interface cable.

In some cases, the offending foreign matter may be removed by gently blowing across the connector with dry air. Air containing moisture or other contaminants should be avoided. A suitable source of dry air is available where camera accessories are sold. They are intended for use in cleaning fine and delicate camera equipment.

If this cleaning method fails to produce satisfactory results, then service by Fluke Biomedical will be required.

A procedure for troubleshooting excessive leakage is given earlier in this section.

4.5 Cleaning the Instrument

To clean the exterior of the instrument, follow these steps:

1.Turn off the instrument and disconnect all input connectors.

2.Place the cap on the detector connector.

3.Moisten a soft cleaning cloth with a solution of three parts water and one part liquid dishwashing detergent.

WARNING

Do not soak the cloth in the solution; you must not let the solution drip inside the instrument.

4.Use the moistened cloth to wipe the instrument’s exterior cover.

5.Let the instrument dry completely before using.
