2-1. Front Panel Controls and Indicators
Kevlltem No. Controlllndicator DescriptionlFunctian
1 Display There are two parts tothe display: the X-axis display
and the.Y-axis display.
X-axis Display The X-axis display shows the current position of the
Mitutoyo Linear Scale connected to the X input.
In the
calculation mode,
it displays either the radius, diameter,
distance, length, height, or X position of the Cartesian
coordinate.
Y-axis Display The Y-axis display shows the current position of the
Mitutoyo Linear Scale connected to the Y input.
In the
calculation mode,
it displays either the angle or Y ,
position of the Cartesian coordinate.

Keylltem No. Controlllndicator Description/Function
3 Skew
Pressing the [RESET] key restores the MICROPAK-2LA
to its initial'condition without clearing previously stored
sets of coordinate data.
The Skew function allows the MICROPAK-2LA to
electronically align the desired part coordinate tothe
machine
X, Y coordinates.
Pressing the [SKEW] key initiates the Skew function.
Pressing the [SKEW] key again aborts the Skew
function. After measurement points have been taken,
each depression of the [SKEW] key clears one
measurement point until all measurement points are
cleared. Once all measurement points are cleared,
pressing the [SKEW] key again aborts the Skew
I
function.
,
Skew indicator This LED indicates the status of the Skew function.
<
When illuminated, the Skew function is activated.
4 Distance The Distance function enables the user to measure the
distance between any two points.
Pressing the [DISTANCE] key initiates the Distance
function.
. Pressing the [CLEAR] key aborts this
function. After measurement points have been taken,
each depression of the [DISTANCE] key clears one
measurement point until ail measurement points are
cleared. After all measurement points are cleared,
further depressions of the [DISTANCE] key have no
effect.
Distance lndicator This LED indicates the status of the Distance function.
When illuminated, the Distance function isactivated.
5 I-Ci(Intersection The I-CL function enables the user tolocate the
of Circle and Line) intersecting point(s) betweena circle and a line.
Pressing the [I-CLI key initiates the lntersection of
Circle and Line function. Pressing the [CLEAR] key
aborts this function. After measurement points have
been taken, each depression of the [I-CLI key clears one
measurement point until all measurement points are
cleared. After
all measurement points are cleared,
further depressions of the [I-CLI key have no effect.
I-CL Indicator This LED indicates the status of the Intersection of
Circle and Line function. When illuminated, the
lntersection of Circle and Line function is activated.

Keylltem No. Controlllndicator . DescriptionlFunction
6 Angle The Angle function enables the user to locate the point
of intersection and measure the angle formed by two
straight lines.
Pressing the [ANGLE] key initiates the Angle function.
Pressing the [CLEAR] key aborts this function. After
measurement points have been taken, each depression
of the [ANGLEI key clears one measurement point until
all measurement points are cleared. After all
measurement points are cleared, further depressions of
the [ANGLE] key have no effect.
Angle Indicator This LED indicates the status of the Angle function.
When illuminated, the Angle function is activated.
7 Orthogonal The Orthogonal function enables the user to: measure
an angle; determine the distance perpendicularly from
one line of the angle to a specified point on the
opposite line; and locate the point of intersection with
the first line.
Pressing the [ORTHOGONAL] key initiates the
Orthogonal function. Pressing the [CLEAR] key aborts
this function. After measurement points have been
taken, each depression of the [ORTHOGONAL] key
clears one measurement point until all measurement
points are cleared. After all measurement points are
cleared, further depressions of the [ORTHOGONAL] key
have no effect.
Orthogonal lndicator This LED indicates the status of the Orthogonal
function. When illuminated, the Orthogonal function is
activated.
The
[XI key is used toeither Zero Set or Preset the
X-axis display.
The [Yl key is used to either Zero Set or Preset the
Y-axis'display.
10 180"-0 The 180°
- O function displays the angle equal to
1
80° - 0. The 180° - O function niay only be used in
conjunction with the Angle or Orthogonal functions.
Pressing the
[I 80° - 01 key generates theangle that is
180 minus the currently displayed calculated angle.
1
80° - O lndicator This LED indicatesthe status
of the 180° - O function.
When illuminated, the 1
80° - O function is activated.

The Sub-Display is used to display either the memory
location
(0 to 50) or the remaining number of points to
be measured (PO0 toP10, depending on the geometric
function selected). The Sub-Display will return to
00
after storing or recalling measurement data and clearing
the function after all points
in a geometric function are
measured.
This LED is illuminated whenever the Store or Recall
functions are activated;
The Store function isused to store a set of coordinate
data at any memory location from
0 to 50. Under
normal operation, the displayed coordinate data is
stored.
In the calculation mode, the calculated point is
stored. Data stored
in memory is not affected bythe
Reset function. However, all data stored
in memory is
lost when the power isturned OFF.
The Recall function isusedto recall the set of
coordinate data or the point data from a previously
stored memory location.
The Bisector function enables the user to calculate half
the distance of a specified line and determine the
location of the bisecting point.
Pressing the [BISECTOR] key initiates the Bisector
function. Pressing the [CLEAR] key aborts this
function. After measurement points have been taken,
each depression of the [BISECTOR] key clears one
measurement point until all measurement points are
cleared. After all measurement points are cleared,
further depressions ofthe IBISECTORI key have no
effect.
This LED indicates the status of the Bisector function.
When illuminated, the Bisector function is activated.
The I-CC function enabies the user to determine the
location of the intersecting point(s1 between two
circles.
Pressing the [I-CCI key initiates the I-CC function.
Pressing the [CLEAR] key aborts this function. After
measurement points have been taken, each depression
of the [I-CCI key clears one measurement point until all
measurement points are cleared. After all measurement
points are cleared, further depressions of the [I-CCI
key have no effect.
This LED indicatesthe status of the I-CC function.
When illuminated, the I-CC function is activated.

the ABSOLUTE or INCREMENTALmode of operation.
Inthe ABSOLUTE mocie, location data is calculated
with respect tothe origin of the current coordinate
system. Inthe INCREMENTALmode, location data is
calculated with respect tothe last measurement
location. While inthe INCREMENTALmode, pressing
the [OTHER] key, switches the displayed data between
ABSOLUTE and INCREMENTAL.
