1 Before Using This Product …………………………………………………………… 1
This chapter explains the product's characteristics, part names and functions, basic operations, and
the settings that must be configured prior to measurement.
1.1
This product is a measuring instrument that makes measurements by vertically moving a part called
a probe into contact with a specific point, and calculating the height of that point. Because the
measurements are obtained from the probe's position, this product can measure the inner diameter of
holes and the outer diameter of cylinders as well.

1.3.3 Moving the Main Unit
When moving the main unit on the surface plate, grab the base with your right hand and the carrier
grip with your left hand.
For QMH-600B/QMH-350B/QMH-24"B/QMH-14"B, pressing the air-float switch on the tip of the carrier
grip causes air to make the main unit float, allowing you to move it smoothly above the surface plate.
NOTE
NOTE
Do not move the product by grabbing parts other than the base or carrier grip. Doing so can negatively
affect measurement accuracy and the product itself.
If using the air-float function:
• Measuring with the air-float function active can cause measurement errors.
• Clean the surface plate in advance.
• Use a surface plate of Class JIS1 or higher. If the surface plate is scratched or uneven, the specified
performance may not be achieved.
• Use a rigid surface plate. If the surface plate warps under the weight of the product, the product
may not float.

NOTE
The airflow has been adjusted to provide optimal performance before shipment. We recommend
using the default settings as much as possible.
When adjusting the air-float flow:
• Due to the characteristics of the air-float mechanism, variations in airflow may cause the main unit
to vibrate. In this case, reduce the airflow.
• If you adjust the airflow, make sure that the friction between the surface plate and the main unit is
reduced before use.

1.4.1 Origin Setup
Set the origin to use when measuring height. The dimensions measured from this origin will become
the height measurements. This product is compatible with both ABS and INC origins. Use one or the
other based on the application.
yABS origin
This method uses a user-defined value as the origin. When measuring the height from the surface
plate, set the surface plate as the origin point with a value of 0 mm.
Example: The surface plate is set as the origin at 0 mm.

1.4.2 Setting the Probe Diameter
The height is calculated using the distance moved by the bottom surface of the sphere attached to the
tip of the probe. (See the left figure below.)
However, when measuring by making contact with the top surface of the sphere, the height will be
measured by adding the diameter of the sphere to the distance moved by the bottom surface of the
sphere. (See the right figure below.)

Specific Usage Applications
Calculating the Difference Between 2
Measurements
There are multiple methods for determining the measurement difference. Use the method that matches
your application.
yDifference with the previous measurement
The difference between the current and immediately prior measurements will automatically be
displayed in the bottom row of the LCD screen. For example, if the previous measurement was 25
mm and the current measurement is 45 mm, [20.000] will be displayed.
The difference with the previous measurement can be checked simply by reading the value
displayed in the bottom row.
Tips
yDifference with a user-defined point
A user-defined point can be set as the comparison point for measurements. For example, set the
surface plate as the origin, and then while continually making measurements, the distance relative
to the surface plate will be displayed each time in the bottom row of the LCD screen.
Tips
yDifference between two measurements stored in memory
The two measurements are stored in the product's internal memory, and the difference between
the two values is calculated. This memory storage method is useful for when you cannot calculate
the measurement difference using the 2 previously described methods, such as obtaining a
measurement difference with a value obtained 2 measurements ago.

Outputting Measurement Results to an External
Device
Depending on the application of the measurement results data can be output to the optional mini
printer or sent to the PC.
3.9.1 Outputting to a Mini Printer (Optional Accessory)
Connecting the optional Digimatic mini-processor (DP-1VR, etc.) to the Digimatic output connector of
this product will allow you to output measurement results. The measurement results will automatically
be output upon completion of measuring. However, you can also output data by pressing .
NOTE
Tips
You can output measurement results when they are displayed. There is no output during a scanning
measurement.
• You can also output measurement results by using optional external devices. For details, see the
accompanying manual for the Digimatic mini-processor.
• By default, the product is set to output the value displayed in the top row of the LCD screen. Use
the following procedure to change the setting to the bottom row.

The indication accuracy and repeatability indicate the values obtained from the height measurement
of a flat surface using the standard ø5 stepped probe. In the case of diameter, maximum (minimum)
value, displacement, or circular pitch measurement, the measured value may be larger than the
accuracy ratings listed in the table due to variation in the measuring force during the scanning
measurement compared to the height measurement.

Perpendicularity indicates the value that is obtained from the measurement of a flat surface placed
parallel with the datum base using the Lever Head (MLH-521) and Mu-checker (M-551).
