12.2 Cleaning the Instrument
First, clean the instrument with a dry damp cloth. If necessary, use a wet damp cloth
with a mild detergent to wash the instrument. Dry the instrument before using it.
12.3 Maintaining Transducers
The ultrasonic transducers used with the 45MG are rugged devices that need little
care. However, they are not indestructible, and some attention to the following items
result in a longer lifespan.
•
Take high-temperature measurements only with suitable high-temperature
transducers. Standard transducers can be damaged or destroyed if brought into
contact with surfaces hotter than approximately 125 °F (52 °C).
•
Cutting, pinching, or pulling the cables causes damage to them. Take care to
prevent mechanical abuse to the cables. Never leave a transducer in any area
where there is a risk that a heavy object could be placed on the cable. Never
remove a transducer from the gage by pulling on the cable; pull on the molded
connector only. Never tie a knot in the transducer cable. Do not twist or pull the
cable at the point where it connects to the transducer.
•
Excessive wear at the tip of the transducer degrades its performance. To minimize
wear, do not scrape or drag the transducer across rough surfaces. Operation of the
transducer may become erratic or impossible in the event that a transducer tip
becomes rough or cracked. Although some wear is normal, severe wear limits
transducer life. Take particular care with plastic delay line transducers; replace
worn delay lines.
12.4 Using Instrument Resets
The 45MG includes reset functions that can be used to quickly restore the gage to its
default parameters. Resets are useful shortcuts to known configurations. The reset
functions are as follows:
