MINI-MAX Ultrasonic Bolt Tension Monitor
value should be very small. Therefore, if the zero is re-calculated and the delta is
very large, something else has gone wrong and the user should become
suspicious of the how well the probe zero was performed.
If we consider the initial probe zero value constant, as the hardware and cal bars
have not been replaced, the future verifications should always show an
elongation value of +/- 0.0001”, in order to be considered “In Spec”. If the probe
zero is out of spec, the user should make adjustments only to the physical
temperature setting in the MINI-MAX. In other words, the primary reason the
probe zero is out of spec is because the physical temperature of the probe zero
calibration standards has changed.
If the accessory temperature sensor is
being used, the sensor will automatically adjust the physical temperature
and the MINI-MAX should be “In Spec” and displaying an elongation value
of 0.0000” +/- .0001”. The next section outlines the verification procedures.
