CALIBRATING WEIGH SCALES USING DROP TEST

Checks or calibrations with check weights cannot reproduce the actual circumstances to perfection.

Highly accurate weighing results can be achieved only by various measurements with material and

subsequent correction.

1. Note down the Feed rate (I tph) say its MA,

2. Collect material over 1 meter of Belt ( say X kg),

3. Note down time taken for 1 meter of Belt (say T sec),

4. Note down Old value of Parameter D 02 (Old)

5. Calculate Actual federate as MW = (X * 3.6)/ T.

Example:

Suppose in INTECONT its reading as MA = 5 tph and MW = 4.9 tph is calculated feed rate by means of drop test.

Also suppose D02 ( Old)= 1. Then

Enter computed value into Parameter D 02.
