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-4600 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 button. The
leveling indicator will appear on the display. Using the
supplied height adjuster on the right side of the unit,
raise or lower until the arrow falls on or close to the “0” in the center of the leveling scale. Once
achieved, press the Enter button to return to the main measuring screen.
Calibration:usingsuppliedreferencestandard
Accuracy of the SRG-4600 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.
Startingmeasurement
1) Starting measurement
Once all parameters have been set, you should place the SRG-4600 on your work piece. In the

Maintenance:
Stylus:
1) After completion of measuring work, please remove stylus from unit and return to case.
2) The stylus is extremely sensitive. Please don’t touch the tip or run it across a surface that hasn’t been cleaned.

Battery:
1）Battery power is shown on the top right side of the display when in main measurement screen.
When the battery symbol is empty, its time to recharge the unit.
2）Approx. charging time is 3 hours.
Calibration Reference Standard:
1) Always keep this clean. Store in carry case when not in use.
2) Avoid scratches to the work area surface of the standard
