Re-Calibrating The Signal Conditioner For Distinct Applications - CenterLine VeriFast MicroView 1.0 User Manual

6.
If the calibration process was successful, re-assemble the MicroView by securing the left side
cover in its place (see Figure 7 above).

Re-Calibrating the Signal Conditioner for Distinct Applications

The calibration instructions shown below may be performed if the values after calibrating the
Signal Conditioner as shown in the previous section (Re-Calibrating the Signal Conditioner for
Most Applications) are not as expected.
The Signal Conditioner returns to Operating Mode immediately after both positions have been set.
Calibration mode can be cancelled at any time by pressing the buttons 'A' and 'B' (see Figure 8
above) simultaneously for 3 seconds.
To calibrate, perform the following steps:
1.
Ensure that the left side cover is still removed from the MicroView (see step 1 in the previous
section).
2.
Ensure that the unit is warmed up for at least three (3) minutes (see step 2 in the previous
section).
3.
Enter the Calibration Mode by pressing both the 'A' and 'B' buttons (see Figure 8) until the
OPER LED will begin blinking (3 seconds minimum).
4.
Move the Pin to its fully retracted position and press the 'A' button once. Wait for the Position
LEDs to stop blinking.
5.
Move the Pin to its fully extended position and press the 'B' button once. The unit will exit the
Calibration Mode automatically and operate with its new calibration. The OPER LED will be
steady ON.
6.
If the calibration process was successful, re-assemble the MicroView by securing the left side
cover in its place (see Figure 7 above).

For certain LVDT weld bodies that have geometric variances, following
the calibration steps above can repeatedly lead to a failed calibration.
In those rare occasions, a slightly modified calibration procedure
should be followed, as illustrated next in the Re-Calibrating the Signal
Conditioner for Distinct Applications section.
