4.7 Interface Connector Cleaning
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
To clean the exterior of the instrument, follow these steps:
1. Turn off the instrument and disconnect all input connectors.
2. Place the caps on both triax connectors.
3. Moisten a soft cleaning cloth with a solution of three parts water and one part liquid dishwashing
detergent.
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.
