Page 12: Checking The Linearity
Evaluation The following conditions must be met: 1) At least two of the calculated values X1 to X3 must be less than or equal to the sum SU. 2) X4 must be within the permissible tolerance of the span. If these conditions are not met, you must proceed as follows: Condition 1) is not met: Adjust the internal linearity (hold down the tare key to select the menu item “LI”) and repeat the test as described in the section “Checking the Internal Span... -

Page 14: Bpi Mode
BPI Mode (RC Models): – Open the balance housing (see page 23). – Connect the balance to AC power, turn on the balance by pressing the key and wait for the balance self-test to finish; 0.0000 g will be dis- played (depending on the type of balance) at the end of the test. -
Page 15: Adjusting The Off-Center Load
SARTORIUS RC/MC-Balances Adjusting the Off-Center Load For this adjustment you will need: – The off-center adjustment key order number 6740–15. – The following weights: 200g for all models (not calibrated!) – Remove the two plastic caps (306) from the rear panel of the balance. - Page 16 – Please adjust only the side with the largest error. In our example it is position 3, consequently you have to adjust the left off-center load screw. – Please adjust the screws in small steps. After each change, check the off- center loading positions 1, 2 and 3 and, if necessary, readjust one of the off-center load screws.

SARTORIUS RC/MC-Balances Linearity Checking the Linearity: Important note: Check the linearity as described in the section “Checking the Linearity” on page 12). External Linearity Adjustment The RC-/MC-balance can be linearized in different ways: 1. the way explained in this service manual;... - Page 18 External Linearity Adjustment (only MC-Balances) Important Note! This adjustment should only be performed in exceptional cases and only on MC-balances (only on MC-balances you have the possibility to enter the exact weight values of the necessary linearity weights using the numeric keys).
-
Page 19: External Span Adjustment
SARTORIUS RC/MC-Balances External Span Adjustment Important: Usually the span adjustment should be performed using the internal adjustment weight. Only in special cases the RC-/MC-balances may be adjusted externally (e.g. if the span accuracy of the internal adjustment weight is out of tolerance). -
Page 20: Overwriting The Internal Linearity Weight
Overwriting the Internal Linearity Weight Important Note! The internal linearity weights only should be overwritten if: • balance was linearized externally • external span adjustment was performed • the linearity was tested externally with known weights (calculate a mean value out of 3 measurements) •... -
Page 21: Overwriting The Internal Calibration/Adjustment Weight
SARTORIUS RC/MC-Balances Overwriting the Internal Adjustment Weight Important Note! Usually the internal ajustment weights should be overwritten using the PSION server or the SARTOCAS program for personal computers and laptops. Only in exceptional cases (e.g. no service software available) the overwriting routine can be performed using the overwriting program of the balance. - Page 22 Internal Adjustment – Make sure that the balance operating menu is set to code “ 1 10 1 “ - internal calibration/adjustment accessible -. RC-A-23.TIF – Press the key (MC) or the key (RC) for at least 3 seconds when a stable readout is displayed.

Page 30: Repairing The Electronics
Repairing the Electronics When repairing RC-/MC-balances, we recommend that you exchange complete component groups if a defect is located, because the two PCBs form an integral unit. The temperature coefficient of both the analog PCB (206) and the digital PCB (204) has been adjusted at the factory. These PCB- specific data are stored in the analog EEPROM (IC220 / analog PCB) and in the AOC (IC107/ digital PCB). -
