Flow-Flow Calibration

F6:Alkali-Alkali flow calibration 12.3 S

12ml:Calibration value 12ml

F7:Acid-Acid flow calibration 12.3 S

F8:Water-Water flow calibration 12.3 S

A. Alkali flow calibration: Connect the graduated cylinder

(about 100ml) with the alkali filler (by the side of the steam tube,

as shown in the Figure 6-4); after that, press "F6" key to select

the alkali flow calibration. After the operation is ended,

record the alkali solution volume in the graduated cylinder.

B. Water flow calibration: Connect the graduated cylinder

(about 100ml) with the water filler (same as that for alkali,

as shown in the Figure 6-5); after that, press "F8" key to select

the water flow calibration. After the operation is ended,

record the distilled water volume in the graduated cylinder.

C. Boric acid flow calibration: Place the "distillate outlet pipe" into

the graduated cylinder; press "F7" key to select the acid flow

calibration. After the operation is ended, record the boric acid

solution in the graduated cylinder.

D. Press "SET" after above steps are completed.

E. Input the recorded volume (mL value) into the corresponding "calibration value".

F. Press "ENT" key after input for save and exit; here, the calibration is completed.

(Note:

The factory calibration of the product is performed by distilled water; as the flowing volumes of the

liquid with different concentrations and proportions will be different at the same time, the user is
