CALIBRATION INSTRUCTIONS

DEFINING ZERO

Unload the system.
Switch the system on.
Push the key for about 8 seconds.
□The display counts down from AF 08 to AF 00.
□ The indicator shows which percentage of the total capacity has been zeroed, e.g. AP 6.4. This percentage should not be higher than 20.
□ The zero point has now been defined, the system automatically returns to standard weighing mode.

CALIBRATION

The indicator offers the possibility to enter a maximum of three calibration points (multiple point calibration). The advantage is that even weighing systems with bad hysteresis can be calibrated within specifications.

Since these instructions are often used in the field, where it is difficult to calibrate various points, we will start with the explanation of single point calibration.

SINGLE POINT CALIBRATION

Deletion (resetting to zero) of earlier calibrated points

Push the 6 key for about 18 seconds (this may be 8 seconds on older versions)
□.htm The display will go blank until calibration mode has been reached.
□ The indicator shows the value of the first calibration point, the “net” pointer is flashing.
Use the 6and 5 keys to see the three earlier programmed values on the screen.
□ When the “net” pointer is lit, the first (lowest) value is shown, the “~” pointer is the second and when both pointers are list the highest value is shown.
□ When calibrating only one point the second and highest values should be returned to zero.
Press the6 or 5 key until the middle calibration value is in the screen.
□ The “~” pointer is flashing.
Press the key.
□ The first segment is flashing.
Use the6 and 5 keys to set the flashing segment to zero.
Change to the next segment by pressing the key.
Set all the segments to zero until the indication bar is flashing.
Press the6 or 5 key until the highest calibration value is in the screen.
□ Both the “net” and “~” pointers are flashing.
Repeat the process until all the segments are set to zero.

Single point calibration

Return to the lowest value.
□ The indicator shows the value of the first calibration point, the “net” pointer is flashing.
Load the weighing system with a known weight and enter this weight on the indicator by pushing the key shortly.
□The first segment starts flashing.
Use the6 en 5 keys to change all segments, confirming the value per segment by pressing the key, until the proper weight has been entered.
□ When each segment has been corrected, the “net” pointer will flash again.
Confirm the entered weight by pressing the key for 3 seconds.
□ The display counts down from AF 08 to AF 00, the first calibration point has been set.
Leave calibration mode by pressing the 6 or 5 key until AP XX appears.
□ This number indicates the calibration sensitivity percentage, e.g. AP 07.
Press the key until the display goes blank.

MULTI-POINT CALIBRATION

Push the6key for about 18 seconds (this may be 8 seconds on older versions).
□ The display will go blank until calibration mode has been reached.
□ The indicator shows the value of the first calibration point, the “net” pointer is flashing.
Load the weighing system with a known weight and enter this weight on the indicator by pressing the key shortly.
□The first segment will start flashing.
Use the ‚5 en 6 keys to change all segments, confirming the value per segment by pressing the key, until the proper weight has been entered.
□When each segment has been corrected, the “net” pointer will flash again.
Confirm the entered weight by pressing the key for 3 seconds.
□ The display counts down from AF 08 to AF 00, the first calibration point has now been set.
Press the 5 key.
□ The “~” pointer will start flashing and the indicator shows the value of the second calibration point.
Load the weighing system with a higher known weight and enter this weight on the indicator, in the same way as described above.
□ Upon confirmation the second calibration point will be set.
Repeat the procedure for the third calibration point.
Leave calibration mode by pressing the 6 or 5 key until AP XX appears.
□ This number indicates the calibration sensitivity percentage, e.g. AP 07.
Press the key until the display goes blank.

After calibration, the indicator automatically switches to a small graduation. Only after switching the indicator off and turning it on again, will the indicator activate the chosen graduation.

Attention: during the start-up sequence of the indicator a calibration number is briefly shown in the display. This number is changed automatically after each calibration.

To view the calibration number:

Switch the system off and then on again.
The indicator shows the following sequence:
□8888.8 (testing LCD segments)
□ P 7.3 (software version)
□ 1342 (the calibration number)
□ 1234.5 (current weight, standard weigh mode).
