With Spindle Clamp loose, turn until measuring surfaces touch. Turn until Ratchet Stop clicks 1 3 times.
For 2050mm range models, please insert the supplied Calibration Standard between measuring surfaces.
Check to Scale to see if it reads "0" and follow the procedure below if necessary.
To align the Thimble Scale 0Point reference lines.
1. Tighten Spindle Clamp to lock Spindle.
2. Insert the spanner into 0point Adjustment Hole on rear of Thimble.
3. Use spanner to rotate Sleeve to align the 0Point lines.
Press the [SET] Button for more than two seconds.
LCD will display "SET" for 0.5 seconds, and then the display will read as shown below:
The gauge is now ready to take measurements.
① Remove any grease or dust from the measuring surfaces using a clean cloth, such as lens cleaning cloth.
Make sure no foreign objects are adhered to the measuring surfaces.
② Place object to be measured between the Anvil and Spindle.
③ With the Thimble Clamp loose, turn the Ratchet Stop to capture the measured object between the measuring surfaces.
Stop after 1 3 Clicks from the Ratchet Stop.
④ The measured value is displayed on the LCD display.
※ Measurement can also be read off Thimble and Sleeve as with a standard micrometer.
For comparative measurements, the display reading can be zeroed at any position by pressing the [ABS/INC] Button.
In this mode, the zero point is retained in memory. Press the [ABS/INC] Button again to return to absolute mode.
Press [ON/OFF] Button to turn power ON; measurement will display on the LCD. Press a second time to turn power OFF.
Always clean measuring surfaces with soft cloth before use.
This is a precision instrument, handle with care. Do not drop or subject to excessive forces.
