Stylus position
Prior to taking a test, whether on your part or using
the calibration reference standard, the stylus
position must be leveled on the application. The
SRG-4500 has a built-in zero indicator to make this
simple and accurate.
Position the unit on the supplied reference standard
or your work piece and press the Enter (back arrow) button. The leveling indicator will appear on
the display. Using the supplied height adjusters on each side of the unit, raise or lower these slides
until the arrow falls on or close to the “0” in the center of the leveling scale. Once achieved, press
the Enter(back arrow) button to return to the main measuring screen.
Calibration
: using supplied reference standard
Accuracy of the SRG-4500 is +/-10% of actual value
Prior to measurement on your parts, you should verify the accuracy of the unit by performing a
quick calibration using the supplied reference standard.
If the difference between the measured value and the specimen value is greater than the
scope of equipment requirements, or user requirements are more accurate, you can use that value
of the calibration function to correct measurement results.
The calibration steps are as follows: (
Must be Calibrated in METRIC mode only
)
1)
Calibration
Press and Hold the Set/Menu button to bring up the
main menu. Use the up or down arrow buttons to scroll
down to Calibration. Press the Enter (back arrow) button to
enter this parameter.
.
2)
Setting correct values
Press the down arow button to choose the closest
roughness value of your part. In other words, if the
roughness of your part is approx. 5µm, you should set
the calibration on the+/-20µm setting. If your part is
approx. 47 µm, you should set calibration under +/-40
µm, etc
