5.8 Abnormal reading
A seasoned operator should be capable to distinguish the abnormal
reading, practically result from rusting, erosive recess surface / incorrect
calibrate sample block/ the inner flaw of material.
5.9 Choose and using coupling agent
Coupling agent serves the high frequency ultrasonic wave transmit-
ting between the transducer to the hardware. Choose incorrect agent or
wrong operation man cause error or poor coupling which lead to failure
of measuring. The coupling agent should be used in proper way, typic-
cally, a single droplet of agent is sufficient.
It is important to use proper coupling agent, low viscosity agent(the
provided agent / machining oil) is suitable for smooth surface. For
rough / veritcal / aluminum surface, high viscosity agent like glycerin
and lubrication grease is applicable. All kinds of coupling agent is
available in local market, you can buy it form local distributor as well.
6. Maintain
6.1 Battery replacement
When low battery icon is showed, please replace the batteries.
A. Press ON/OFF to turn off.
B. Open the battery door properly.
C. Replace the low power batteries by new batteries in correct polarity.
When the gauge is not use for long period, please take out the batteries.
.
6.2 Protection of transducer
Because the wear face of transducer is propylene material which easy
to be scratched. During taking measurement on rough material, please
using the transducer in gentle motion. The temperature of the hardware
should not over 60℃, otherwise it will cause damage on the transducer.
Adhering oil, dust on the wear face will speed up aging of transducer
and lead to rupture. Clean the lead-wire & transducer after use.
