4.7 Interface Connector Cleaning
WARNING
Select 0.0 V bias setting AND turn off the Model 35040 Therapy Dosimeter 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 that may have a detrimental affect upon the accuracy of radiation measurements.
The ends of the interface cable may 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 Model 35040 Therapy Dosimeter 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 will be required.
A procedure for troubleshooting excessive leakage is given earlier in this section.
4.8 Cleaning The Instrument

1.Turn off the instrument and disconnect all input connectors.
2.Place the caps on both triax connectors.
