Procedure of Operation
Preparation for Operation
Visual Inspection
Make visual inspection of the device, making sure that there is no mechanical damage to the electronic
transducer, connective cable.
Surface Preparation
Prepare the area of the tested surface by removing moisture, lubricants, scale, oxidation, rust, etc.
The roughness of the part to be tested and radius of curvature of the tested surface and also mass and
size parameters of the article shall correspond to the parameters given in the hardness tester data
sheet.
Transducer Connection
Transducer shall be connected to the electronic module by a five-pin plug. The transducer plug is
equipped with a rotating cylindrical lock
To connect the transducer, make the following steps:
•
turn the lock counterclockwise up to the stop;
•
Insert the plug of the transducer into the 5-pin female port by pushing slightly
•
turn the lock
clockwise
slightly until you feel it lock.
Power Unit On
•
Press
Ð
button to power on the hardness tester
•
The MET will automatically recognize the type of transducer and will show the results on the
display by showing either ‘ultrasonic transducer’ or dynamic transducer’
•
after the hardness tester performs this start up procedure, the hardness tester will show the last
parameters used and start up in the “Archive” section.
Power Supply Switching Off
•
The MET will automatically shut off after a 3 minute period of non-usage.
•
To Manually shut off the unit, Press the
ÍÎ
buttons simultaneously.
