8. CALIBRATION

CALIBRATION INSTRUCTIONS INDICATOR 310
The calibration mode can only be reached from the standard weighing mode. You cannot get into the
calibration mode when you are in piece count mode.
DEFINING ZERO
 Unload the system.

Switch the system on.
 To enter the zero calibration mode press the >0< key for 10 seconds.
 After 3 seconds the display will show the last entered code.

After 7 seconds the display will go into the zero calibration mode and start adjusting.
 The display will show "Adj08" and run down until "Adj00". The adjustment has been completed.
 The indicator shows the percentage of the total capacity that was adjusted. For a normal scale
this would be between 5 and 8 percent. A larger percentage could mean one or more load
cells are broken. A lower percentage could mean the fork cover is not mounted.
 The zero point has been defined, the system automatically returns to the standard weighing
mode.
SINGLE POINT CALIBRATION
Press the T key for about 30 seconds until you see UNIT in the screen.

When you see UNIT you press the ↵ key to continue

 The display will show the first calibration point with the pointer "e1" flashing.
Press the ↵ key to be able to change the calibration weight on "e1".

Using the ∧ and ∨ keys you can see the three earlier programmed values on the display.

 The pointer will move through e1-3. "e1" is the first calibration point, "e2" the second and "e3"
the third.
When calibrating only one point the second and third values should be set to zero.
Use the ∧ and ∨ keys to move to the second calibration point.

 The display will show the pointer "e2" flashing.
Press the ↵ key.

 The display will show the previously entered calibration value, with the last segment flashing.
Use the ∧, ∨ and < keys to return all the segments to zero.

Press the ↵ key.

Use the ∧ and ∨ keys to move to the third calibration point.

 Repeat the above to set all the segments to zero.
Press the ↵ key.

Calibrating the single point
Use the ∧ and ∨ keys to return to the first point.

 The indicator shows the value of the first calibration point, with the "e1"pointer flashing.
 Load the scale with a known weight.
Press the ↵ key to enter this weight onto the indicator, the first segment starts flashing.

Use the ∧ and ∨ keys to change all the segments until the proper weight has been entered.

Press the ↵ key to return to calibration mode. The "e1" pointer will start flashing.

Press the ↵ key for 3 seconds to confirm the entered weight.

 This calibration number counts down from Adj 08 to Adj 00, the first calibration point has now
been set.
Leave the calibration mode by pressing the ∧ or ∨ key until AP XX appears. This number indicates

the calibration sensitivity percentage, eg AP 07.
Press the ↵ key.

The display now shows the value of the gravitation constant. Use the ∧, ∨ and < keys to

correct this for your position.
Press the ↵ key to return to the standard weighing mode.
