ACCS.
Always follow the procedures specified below in order to prevent harm to
yourself or others, and to prevent damage to property.
Always clean measuring surfaces with soft cloth before use.
Do not turn spindle more than 3mm above upper measurement range.
When turning Thimble, be gentle and do not apply force. High force on Thimble will
cause inaccuracy.
This is a precision instrument, handle with care. Do not drop or subject to
excessive forces.
Keep instrument away from direct sunlight or high temperatures such as in a car,
or near a stove or heat source.
Do not expose to water or oils.
Do not disassemble or modify.
After use, remove any chips or debris using a soft cloth and take appropriate
rust-preventive measures. Keep out of reach of children.

Gauge includes a Mechanical Counter for use as a quick reference
display in addition to the measurement shown conventionally on the
Sleeve Scale. Please note the following points about the measurement
displayed on the Mechanical Counter:
1. Use the reading from the Mechanical Counter only as a guide.
Since the Counter is a gear driven mechanism, there is some
backlash error and it will not necessarily match the reading on the
Sleeve/Thimble. When there is a discrepancy, please treat the
measurement shown on the Sleeve Scale as the correct value.
The specifications listed for this product are for the measurement displayed
on the Sleeve Scale. The Counter reading is only to be used as a guide.
2. In the unlikely event that the Counter and Scale readings deviate
significantly, use the following procedure to adjust the Counter display.
Please note, before adjustment check that the Sleeve/Thimble zero
setting is correct.
For MC122-50C, use the provided Calibration Standard between the
Measuring Surfaces.Using a precision
type screwdriver, remove the two screws
securing the Counter Cover Plate, and then the two additional
screws holding the Counter Module in place. Fig.4
Remove the Counter for access, and rotate the gear to adjust. Set the
counter to 0.02 0.03 above the reference value. Fig.5
Hold the Counter Module by the outer frame without touching the
counter dials or gears, and replace the Module into the Micrometer
body. Fig.6
If you touch the counter dials or gears the value may change when
being inserted.
Replace the Counter Module screws to secure, and then replace the
Counter Cover Plate and screws.
Use a lens cleaning cloth or similar to clean the Anvil and Spindle of
any grease or debris.
Loosen the Clamp and place the workpiece between the Measuring
Surfaces.
Rotate the Thimble using the Ratchet Stop until the workpiece contacts
the Measurement Surfaces and the Ratchet clicks 1 3 times. Fig.7
A rough reading is displayed on the Counter display.
For a precise measurement please read the value shown on the
Sleeve/Thimble Scale. Fig.8

Measurement (mm)
Rotate the gear to set the
reference value:
MC122-25C 0000
MC122-50C 2500
Set counter to 0002 0003
above ref. value.
Remove any grease or dust from the measuring surfaces using a
clean cloth, such as a lens cleaning cloth.
Make sure no foreign matter is adhered to the measuring surfaces.
With Spindle Clamp loose, turn until measuring surfaces touch.
Turn until Ratchet Stop clicks 1-3 times. Fig.1
For MC122-50C, place the provided Calibration Standard between the
Measuring Surfaces.
If the zero line on the Thimble lines up with the line on the Sleeve, then
the origin is set. Fig.2
If they do not line up, adjust the zero-point according to the procedure
below.
1. Tighten Spindle Clamp to lock Spindle.
2. Insert the spanner into 0-point Adjustment Hole on rear of Sleeve.
3. Use spanner to rotate Sleeve to align the 0-Point lines. Fig.3
