MANUFACTURERS OF SPECIALIST TEST EQUIPMENT DTU6 Operating Instructions English Version Please read carefully before use

Description The DTU6 unit is designed to deliver an adjustable stabilised DC output voltage of 500V to 6kV for the detection of pinholes or porosity in dielectric (insulating) protective coatings applied to the metal substrate of a diathermy instrument. Fault detection is indicated by an audible alarm and a red LED on the front panel. There are two conditions that will cause an alarm: • A transient current pulse, caused by the ionisation of the air that exists in an imperfection of the coating material. Upon transient fault detection, the high voltage generator is momentarily disabled, during...

Setting the test voltage It is important to choose an appropriate test voltage – it must be sufficient to ensure that faults are detected, but not so high that it may cause damage to the items being tested. There are various published specifications for voltage calculation and the surgical instrument manufacturer may also have published suitable test voltages. If these are not available, it is necessary to know the coating material and minimum acceptable thickness in order to establish the necessary voltage for the test. The voltage must, in all cases, be sufficient to arc across an air gap of...

Instruction Manual Maintenance The DTU6 was designed for minimum maintenance by the user, however the following periodic checks/actions are recommended. • • • • Check the HT return lead for continuity. Keep the unit clean so that the control wording can be seen. Send the equipment back to the manufacturer or their agent for recalibration at yearly intervals. Remove the batteries if the unit is not in use for prolonged periods. Troubleshooting Q. Alarm sounds for no apparent reason as the test instrument is moved over the electrode. A. Is the surface clean and dry? Moisture on the surface is conductive;...

Risk Assessment It the user’s responsibility to complete a risk assessment before using Buckleys equipment. The following points offer some guidance but must not be assumed to be complete or sufficient. Personal safety  Have all users been trained in the correct and safe use of the instruments?  Are they aware that the instrument produces high voltages, and can give electric shocks if used incorrectly?  Is the instrument in good condition, undamaged? Is the instrument dry? Are the accessories similarly in good condition, dry and undamaged?  Is it possible to ensure that persons with pacemakers,...
