p.20

3. Warming Up

After turning the power supply ON, allow the product to stand for at least 10 minutes before use. The circuits are still unstable just after the power supply is turned ON, so measurement values may fluctuate gradually.

4. Maintenance and Inspection

Do not use thinner, benzene, acetone or kerosene to clean the Sensor and Controller. If large dust particles adhere to the filter on the front of the Sensor, use a blower brush (used to clean camera lenses) to blow them off. Do not use breath from your mouth to blow the dust off. To remove dust particles from the Sensor, wipe gently with a soft cloth (for cleaning lenses) moistened with a small amount of alcohol. Do not use excessive force to wipe off dust particles. Scratches to the filter might cause error.

BASIC OPERATIONS

Executing and Canceling a Zero Reset

When the zero reset function is used, the measured value can be reset to a reference value of 0 when the ENT key is pressed or an external signal is input.

The analog output shifts to the minimum measurement value (4 mA or -5 V) when a zero reset is performed. If output scaling is set, the shift is to the scaled minimum value. If an offset value is set for the zero reset, the output is set to the output value that corresponds to the display value.

Executing/Canceling a Zero Reset by External Signal Input p.126

When the Controller is turned OFF, all settings are cleared from memory (i.e. are returned to their defaults). This setting can also be changed so that settings are saved in memory when the power is turned OFF.

How to count edge Nos.

• Set different edges for the 1st and 2nd edges.

• The 1st and 2nd edges can also be set and measured in the reverse order. Note, however, that the following restrictions apply:

- The same edge No. cannot be set twice.

- When "49" is set to one edge, be sure to set "50" to the other edge.

- When "50" is set to one edge, be sure to set "1", "2" or "49" to the other edge.

General measurement

Edge Nos. are assigned from 1 to 30.

In the specified edge measurement mode, the top edge of the beam is always 1, and the bottom edge is always the last edge.

Special measurement

How the edge No. is counted differs according to measurement of (a) to (c) in the figure below.

(a) Width from top edge of beam to last interrupted beam section (distance from edge 1 to 50)

(b) Width from first interrupted beam section to last interrupted beam section (distance from edge 2 to 50)

(c) Width of last interrupted beam section (distance from edge 49 to 50)

Though edge Nos. are generally assigned within the range 1 to 30, 49 is set when setting the top edge of the last interrupted beam section, and 50 is set when setting the bottom edge of the last interrupted beam section.
