•Touch Pad
- There’re 3 sections on the touch pad that have their own function. The below functions are exceeded
if each sections are touched.
1. Main menu entrance: To enter the main menu, touch the ‘MENU’ area.
2. Absolute / Relative value change area : To change the X / Y to absolute or relative value. (ABS ↔ REL)
- Absolute value : The displayed values of X / Y are from the absolute coordinate system.
The absolute coordinate system is set from the factory or user’s updating at the calibration menu.
- Relative value : To make current X / Y values to zero.
3. Tilt direction display area : To change the tilted direction display method. (Line ↔ bubble)

3. Spec
- To setup the spec. for the FLAT mode.
1. Go Back : To exit the ‘Spec’ menu.
2. Tolerance : To setup the tolerance of the tilted direction display line.
3. Model : 10 memory spaces are given to save the users’ specification
setting. And user could recall them later.
4. X : The width of the setting points.
5. Y : The length of the setting points.
6. Pitch : The pitch of the screwed legs at the home appliances or other
machines.
7. Angle : It is set by 360 deg. normally.
4. Calibration
- To calibrate the absolute zero. Please follow the steps carefully.
If not, it can not be guaranteed the angle data.

Step 1 [XY Calibration]
Put the inclinometer on the surface as like Fig.1 and choose
the ‘XY 1st’. Then you might see ‘XY 1st Please Touch Screen’.
If the inclinometer is settled well on the surface, touch the screen
and wait until the inclinometer gathers the data and averages them.
Put the inclinometer as like Fig.2 and choose the ‘XY Rev’.
And touch the screen if the inclinometer is settled.
Step 2 [X Calibration]
Put the inclinometer on the surface as like Fig.3 and choose
the ‘X 1st’. Then you might see ‘X 1st Please Touch Screen’.
If the inclinometer is settled well on the surface, touch the screen.
Put the inclinometer as like Fig.4 and choose the ‘X Rev’.
And touch the screen if the inclinometer is settled.

* [Y Calibration]
User doesn’t have to do the Y calibration because the Y calibration
is done automatically if the X calibration is done.
* [Default]
If the calibration is not done well, user can choose the ‘default’.
Then IM-2DT will recall the zero setting values at the factory.

Functions
5. Average
- To change the number of inputting row data to average them. It can be set from 1 to 30.
6. Display
- To change display options as like brightness, display off time, etc.
1. Go back : To exit the ‘Display’ menu.
2. Touch Calib. : To calibrate the touch pad.
It is the same with pushing the master button for over 5 sec when power is on.
3. Brightness : To change the brightness of the screen.
4. Display Off : To change the display on time. The screen will be off after this time.
5. Power Off : To change the power on time. The power will be off after this time.
6. Line width: To change the width of the tiled direction indicating line
at the POLE mode
[ Touch pad calibration method ]
- Just touch the blue crosses at the five points in order.
7. Serial
- To change the RS232C serial output method.
1. Poll mode : There’re 4 RS232C output method as like below.
- Command : X / Y data is outputted once whenever it gets ‘CALL+ID’ command.
( Default ID is 00 so that the command should be ‘CALL00’ )
- Polling : X / Y data is outputted continuously.
- Polling 1 sec. : X / Y data is outputted every 1 sec.
- Polling 10 sec. : X / Y data is outputted every 10 sec.
2. ID : IM-2DT can have the id from 0 to 99
so that user can get the tilted data from the various IM-2DTs.
8. Save**
- To save whatever user has changed, it should be done. If user doesn’t want to save the current
changes, just turn off the power by pushing the master button for around 2 sec.
9. About
- To see the information of the manufacturer.

How to use the FLAT mode
FLAT mode is used to adjust the 4 legs machines, as like laundry machine, etc., very easily.
There are shown the 3 points, that makes a plane, with the heights to raise up.
P1 :
It should be up 19.2mm
(1.9 turns up if there’s
a screwed leg)
P2 :
The highest point.
So, it doesn't have to be
raise up anymore.
P3 :
should be up 196.42mm
(19.6 turns up)
P4 :
Floated point
(It should chosen by user.)
* The floated point should be taught by user. It could be P1, P2, P3, or P4 depend on situation.
If user touches the area of the floated point on the screen, IM-2DT calculates and displays the heights of the
other 3 points. The floated point should be filled up at the last after user finishes to adjust the 3 points level.
** Before measuring!
To use this flat mode, user also has to set the below parameters.
1. Model : 10 memory spaces are given to
save the users’ specification setting. And
user could recall them later.
2. X : The width of the setting points.
3. Y : The length of the setting points.
4. Pitch : The pitch of the screwed legs at the
home appliances or other machines.
5. Angle : It is set by 360 deg. normally.
