MINI-MAX Ultrasonic Bolt Tension Monitor

Setting up the MINI-MAX for Measurement

Note: Check to see if the system was previously calibrated. You should

NOT change the calibration unless the transducer, transducer cable, or

instrument has been changed. In any event, the probe zero calibration

should always be checked prior to changing it and only changed if it is

required, as you can introduce error by uncertainty during the zero

procedure. If the MINI-MAX has been previously calibrated, open the

calibration data saved in the MINI-MAX and check the probe zero by simply

measuring the bars in an empty location (columns B – ZZ) in the existing

probe zero data group. If the zero is slightly off, minor adjustments to the

temperature, located in the Main Measure Menu, should be all that’s

necessary to bring the error between the two bars within a tolerance of

.0005”.
