would be needed for the minimum and maximum boundaries of the test range. Using the
range above, a one point calibration would be performed at .250” (6.35mm) and a two
point calibration at .080” (2.03mm), or something close to the min/max values of the
measurement range.
NOTE:
The TI-007DLX also offers the capability of setting the ‘probe zero’ to use any
reference standard as the ‘probe zero’ standard. For clarification, if it’s desired to use a
one inch reference of a specific material type as the ‘zero’ reference, performing the first
point of a two-point calibration sets the internal zero of the TI-007DLX . This should
be used only in manual probe zero mode “on block”.
The following steps outline this procedure:
Two Point Calibration
1. Physically measure a minimum and maximum calibration point of the exact sample
material, or locations directly on the material to be measured, using a set of calipers
or a digital micrometer.
NOTE:
A sample or location on the test piece should be used as close to the minimum
and maximum thickness of the test range to minimize error and improve linearity.
2. Apply a drop of couplant on the transducer and place the transducer in steady
contact with either the minimum or maximum sample or actual test material. Be sure
that the reading is stable and the repeatability indicator in the top left corner of the
display is fully lit and stable.
3. Press the key to enter the calibration edit screen displaying the current
measurement value.
4). Use the and keys to scroll to the known thickness value.
NOTE:
The longer the keys are pressed and held, the faster the value will increment/
decrement.
NOTE:
Pressing the key prior to pressing the key will abort the cal
routine without saving any changes.
5. Once the known thickness value is being displayed, press the key to display
“1 of 2”, which sets the zero value and returns to the measurement screen.
NOTE:
The internal zero of the TI-007DLX is now set. The procedure above can be
used to set the internal zero of the TI-007DLX to use any reference standard as the
‘probe zero’ standard if desired.
