1 Overview

Our columnar electronic micrometer features color bars of three different colors, which makes the display easy to see. The meter also features an automatic master matching function. It can be used by itself or can easily be deployed in complex combinations with other components. With the bar displays arrayed next to each other, the property of the object being measured can be ascertained.

2 Features

(1) Displays measurement results clearly using a three-color color bar display. (2) With an eight-digit display, it can display such information as measured values and setting

names.

(3) Master alignment for both large and small limits can be accomplished at the push of a

button. (4) Because the instrument is only 50mm wide, it can be used in a series configuration. (5) With the serial communications function (included standard), data can be output to a PC and

printer. The data can be saved and input into statistical and spreadsheet applications (such as

Microsoft Excel). (6) In the Set-up Mode, all settings can be entered in order by pressing the ENT key. (7) Up to 10 different sets of settings and master values can be saved and selected from.

3Operation

This instrument has the following four principal modes of operation:

(1) Measurement mode

• Measurement mode Measures

• Hold measurement Saves the measured values However, if master matching was unsuccessful, the values are not saved.

(2) Set-up Mode

• Set-up Mode Inputs or changes settings.

(3) Master matching mode

• Master matching Matches with a master. This instrument conducts comparative measurements, so only use it after having measured a master for comparison.

• Adjust detector (ADJ) This will adjust the detector.

• Clear master match This will clear master match data.

(4) Program switching mode

• Program switching mode Switches programs. The instrument launches with the last program that was used before it was last shut down.

6.1 Overview

• What to do when the detector has been connected and adjusted and the settings have already been entered.

• What to do when the measurement head has been replaced

In this section, we will explain the procedures for the above two situations.

6.1.1 What to do when the detector has been connected and adjusted and the settings have already been entered.

Please use the following procedure.

(1) Power on

Turn on the power switch in the rear of the unit (press the side marked with a circle) to supply power (85-265V AC and 50/60Hz). The unit will start up in Measurement Mode.

In Measurement Mode, hold down the right arrow (MAS) key for two seconds. Holding the key down for an additional two seconds switches to Clear Master Match.

(2) Clearing the master matching data

Clear the master matching data as necessary. For details, refer to 6.4.3 “Clearing the Master Match.”

(3) Master matching

Now match to a master. For details, refer to 6.4.1 “Master matching.”

(4) Measuring

In Measurement Mode, press the ENT key once, the unit will be set to Hold Measurement Value. This can be cleared by pressing the RST key. However, if the master match was unsuccessful, the measured value cannot be saved. For details, please refer to 6.2 “Measuring.”

-7-

Page 11

6.1.2 What to do when the measurement head has been replaced

Please use the following procedure.

(1) Connection

Connect the detectors to the front of the column unit and the included power cord to the back.

(2) Power on

Turn on the power switch in the rear of the unit (press the side marked with a circle) to supply power (85-265V AC and 50/60Hz). The unit will start up in Measurement Mode.

In Measurement Mode, hold down the left arrow (SET) key for two seconds, which will switch to Set-up Mode.

(3) Inputting setting values

Please input the setting values. For details, please refer to 6.3 “Set-up mode.”

In Measurement Mode, hold down the right arrow (MAS) key for two seconds. After that, pressing the key down once switches to Adjust Detector (ADJ).

(4) Adjust Detector

Please adjust the detector. For details, refer to 6.4.2 “Adjusting the detector.”

In “Adjust Detector” mode, holding down the ENT key for two seconds switches to Master Matching.

(5) Master matching

Please match to a master. For details, refer to 6.4.1 “Master matching.”

(6) Measuring

In Measurement Mode, pushing the ENT key once switches to Hold Measured Values. This can be cleared by pressing the RST key. However, if the master match was unsuccessful, the measured values cannot be saved. For details, please refer to

6.2 “Measuring.”

4) When master matching is performed one at a time, master matching is performed for the item currently shown in the bar display. Use the up and down arrow keys to toggle between the items that master matching will be performed on. The Item/Decision Lamps show which item is currently shown in the bar display. When “1” is lit, it means that Item 1 is displayed. When “2” is lit, it means that Item 2 is displayed.

5) Set the small master to a detector, and when the bar display stabilizes, press the ENT key.

6.4.2 Adjusting the detectors

No adjustment is required except after the measurement head is replaced.

1) ZERO ADJ (zero adjustment) In the following procedure, the small master is used to match the small master value and the bar display position.

(a) In Measurement Mode, hold down the right arrow (MAS) key for at least

two seconds.

(b) The “MAS” LED (orange) will light up, “MIN M.” will be displayed, and

the unit will switch to Master Matching Mode.

(d) The unit will switch to Detector Adjustment Mode and “ADJ” will be

displayed.

(e) Use the up and down arrow keys to switch to the item to be adjusted (Item

1 or 2). The item currently shown in the bar display is indicated on the Item/Decision Lamps. In addition, the Detector Name for the measuring unit the item is using for measurement is shown in the eight-digit display.

(f) Press the ENT key.

(g) “ZERO ADJ” will be displayed.

(h) Press the ENT key.

(i) The name of the measurement unit that the item selected in (e) uses, as well

as its current ZERO ADJ setting will be displayed.

(j) If the ZERO ADJ setting is not displayed, it is because the item selected in

E has data for two measurement units. Use the left and right arrow keys to toggle between the ZERO ADJ settings for the two units.

(k) Set to small master and use the up and down arrow keys to adjust each

measurement units ZERO ADJ setting so that the item’s data approaches the small master setting.

(l) After setting is compete, press the ENT key.

(m) “GAIN ADJ” will be shown in the eight-digit display. Proceed to set the

GAIN ADJ setting.

-17-

Page 21

2) GAIN ADJ (sensitivity adjustment) In the following procedure, both small and large masters are used to match the small and large master values with the bar display range.

(a) With “GAIN ADJ” displayed, press the ENT key once.

(b) The measuring unit that the item selected in 6.4.2 1) (e) uses, as well as the

current GAIN ADJ setting value, will be shown in the eight-digit display.

in 6.4.2 1) (e) has data for two measuring units. Use the right and left arrow keys to toggle between the data for these two measuring units.

(d) Alternately set the small master and the large master, and use the up and

down arrow keys to adjust each item's measurement unit GAIN ADJ setting so that it approaches the small master setting and the large master setting.

(e) After these settings are complete, press the ENT key.

(f) “MAG ADJ” will be displayed. That concludes the GAIN ADJ setting

input procedure.

(g) Proceed to input settings for MAG ADJ.

3) MAG ADJ (fine sensitivity adjustment) The following procedure is used to set the coefficient for each item when one item has two measuring units. This should be set to 1,000 for most purposes.

(a) With “MAG ADJ” displayed, press the ENT key once.

(b) The name of the measuring unit that the item selected in 6.4.2 1) (e) uses

will be shown in the eight-digit display, along with its current MAG ADJ setting.

6.4.2 1) (e) has data for two measuring units. Use the left and right arrow keys toggle between the data for each one.

(d) Use the up and down arrow keys set the GAIN ADJ for each measuring

unit.

(e) After these settings are complete, press ENT.

(f) “MIN M.” will be displayed and the unit will switch to 6.4.1 “Master

Matching.” This concludes the MAG ADJ setting procedure.
