DMTA-10022-01EN, Rev. C, January 2015Chapter 1220012.2 Cleaning the InstrumentFirst, clean the instrument with a dry damp cloth. If necessary, use a wet damp clothwith a mild detergent to wash the instrument. Dry the instrument before using it.12.3 Maintaining TransducersThe ultrasonic transducers used with the 45MG are rugged devices that need littlecare. However, they are not indestructible, and some attention to the following itemsresult in a longer lifespan.• Take high-temperature measurements only with suitable high-temperaturetransducers. Standard transducers can be damaged or destroyed if brought intocontact with surfaces hotter than approximately 125 °F (52 °C).• Cutting, pinching, or pulling the cables causes damage to them. Take care toprevent mechanical abuse to the cables. Never leave a transducer in any areawhere there is a risk that a heavy object could be placed on the cable. Neverremove a transducer from the gage by pulling on the cable; pull on the moldedconnector only. Never tie a knot in the transducer cable. Do not twist or pull thecable at the point where it connects to the transducer.• Excessive wear at the tip of the transducer degrades its performance. To minimizewear, do not scrape or drag the transducer across rough surfaces. Operation of thetransducer may become erratic or impossible in the event that a transducer tipbecomes rough or cracked. Although some wear is normal, severe wear limitstransducer life. Take particular care with plastic delay line transducers; replaceworn delay lines.12.4 Using Instrument ResetsThe 45MG includes reset functions that can be used to quickly restore the gage to itsdefault parameters. Resets are useful shortcuts to known configurations. The resetfunctions are as follows:MEASUREMENT RESETChanges the measurement parameters to the default factory values listed inTable 14 on page 201.
