Procedure 4: How to calculate the mechanical calibration speed and the measurement
offset (OPTIFLEX 2200)
1 Install the device on the tank.
2 Energize the device. Make sure that the display screen shows "Distance" measurements.
i The device is in operation and in normal mode. It will not measure correctly until it is
correctly calibrated.
3 Change the level to R1.
4 Record D1, the distance shown on the display screen of the device.
5 Change the level to R2.
6 Record D2, the distance shown on the display screen of the device.
7 Calculate the ratio, A. A = (D2 - D1) / (R2 - R1).
8 Calculate the new mechanical calibration speed. New mechanical calibration speed
(OPTIFLEX 2200) = Old calibration factor (BM 100) × A
9 Calculate the offset, B. B = D1 - (A × R1).
10 Calculate the new measurement offset. New measurement offset (OPTIFLEX 2200) = Old
converter offset (BM 100) × A
Procedure 5: How to set the mechanical calibration speed and the measurement offset
(OPTIFLEX 2200)
1 Energize the device.
i The device is in operation and in normal mode. It will not measure correctly until new
values are set in menu items 3.1.4 OFFSET MEAS. (Measurement Offset) and 3.1.6 M.CAL.
SPEED (Mechanical Calibration Speed).
2 Push [> >>>], 2 × [ ] and [>>>>] to go to the SERVICE menu (3.0.0).
3 Give the password for the SERVICE menu. If you do not have the password, speak to the sup-
plier.
4 Push [> >>>] and 3 × [ ] to go to menu item 3.1.4 OFFSET MEAS.
5 Push [> >>>] to change the value. Enter the new measurement offset value that you calculated in
procedure 4.
6 Push [^ ^ ^ ^], 2 × [ ] to go to menu item 3.1.6 M.CAL. SPEED.
7 Push [> >>>] to change the value. Enter the new mechanical calibration speed value that you cal-
culated in procedure 4.
8 Push 4 × [^ ^ ^ ^]. Push [ ] or [ ] for the selection of the save option (STORE NO or STORE YES).
Set to "STORE YES" to save and use the data.
9 Push [^ ^ ^ ^] to confirm.
i The device is in normal mode. The device uses the new values.
Procedure 6: Device configuration (OPTIFLEX 2200)
• For the Quick Setup procedure, refer to Quick Setup on page 80. For more data about device
configuration, refer to Operation on page 67.
CAUTION!
You recorded device configuration data of the BM 100 level meter before you attached the new
signal converter. Make sure that you enter this data in the supervisor menu of the OPTIFLEX
2200.
