DISPENSING INTO SAMPLE CONTAINER

Without pressing any buon,

need to reach a preset quantity.

K900 is informed that the calibration dispensing operation is ﬁnished.

Make sure dispensing is correctly ﬁnished before performing this operation.

To calibrate K900, the value indicated by the partial totaliser (example 155.20) must be

forced to the real value marked on the graduated sample container. In the boom le

part of the display an arrow appears (upwards and downwards), that shows the direc-

tion (increase or decrease) of the USER K FACTOR value change when the operations

6 or 7 are performed.

SHORT RESET KEY KEYING

Changes the direction of the arrow. The operation can be repeated as many times as

you wish

SHORT/LONG CAL KEY KEYING

The indicated value changes in the direction indicated by the arrow

- one unit for every short CAL key keying

- continually if the CAL key is kept pressed.

(for the ﬁrst 5 units slowly and then quickly).

If the desired value is exceeded, repeat the operations from point (6).
