3. FUNCTIONAL DESCRIPTION

First, we will describe the functions of each part, as used in the

normal basic measurement function. Of the EG-225 parts, the

operation in the absolute zero or preset function will be noted

only when it is different from operation in the normal function.

a Power Switch

When the power switch is pressed, the EG-225 is powered and

measurement is possible. When this is done, the LCD display

reads “0”.

b Reset Switch

When this reset switch is pressed and then released (within two

seconds), the display value is reset to “0”. When this happens,

the output is “no data” when the reset switch is pressed and the

display is blank, and is “0” when the reset is released and the

display changes to “0”.

When the switch is allowed to return to its original position, “0” is

indicated on the display and the current spindle position is the

zero point.

c Direction Switch

The measured value is incremented or decremented, depend-

ing upon the direction of spindle movement.

The counting direction can be selected either to add or subtract

when the spindle is pressed in, depending upon the setting of

the direction switch.

The counting mode is indicated by the or mark on the dis-

play.

: Addition (+ direction) when spindle is pushed in.

: Subtraction (– direction) when spindle is pushed in.

d Mode Switch

Each time the mode switch is pressed within two seconds, the

mode is sequentially changed from the normal measurement

mode to the maximum value, the minimum value display mode,
