If absolute value of zero is more than value of relative tolerance, but less than absolute tolerance, the situation may require acceptance of "new zero".

Click on every flash button.

If scale showed less than "0" while empty, yellow line of current weighing result would be on the left side from white vertical line (like on the picture), if more than "0" - on the right side. Same time if its absolute value is smaller than value of relative tolerance: zero is OK.

White vertical line represents "zero": if empty scale is showing "0" as weighing result, zero value equals "0" (ideal situation - no yellow line).

Current measurement deviation

Absolute toleranses, outside which mix is admitted non_conforme

White line represents theoretical weight ("zero")

If absolute value of zero is more than value of absolute tolerance, zero is NOT OK.

Relative tolerances

Use of "zero" as the theoretical weight

On the scale images, "zero" represents theoretical weight requested by formula. Red and violet lines indicate when you are out of tolerance. Yellow indicator that might be situated on the left or right of vertical white zero control line represents current deviation measurement.

Asks the operator to find the origin and then check the zero again

Absolute tolerance (-)

Zero relative

Absolute tolerance (+)

Zero taken automatically without asking the operator

Relative tolerance (-)

Relative tolerance (+)

Ask the operator to check again the zero or to accept it, if no other solution

ZERO CHECK

Asks the operator to clean the scales and then check the zero again

Zero absolute

If he is unsuccessful, then call the site scale technicians for assistance

Ask the operator to check again the zero or to accept it, if no other solution

The absolute value of zero more then "0", but less then relative tolerance.

If our empty scale shows 45 g, zero value is "+45" and yellow line is on the right side from white vertical line, but its length is not long enough to cross violet boarder of relative tolerance (relative tolerance is 50): Zero is OK.

zero is OK

Ideal situation: yellow line is absent. Real "zero" value is "0".

ZERO EQUALS "0"

Absolute value of zero is more than absolute tolerance.

When scale is empty if zero value is "+105" and yellow line is on the right side from white vertical line crosses red line of absolute tolerance (+100): zero is NOT OK.In this case: our zero is in accepted measures of relative deviation of "new zero", but we would take into account only absolute tolerance value.

zero is not ok

Absolute value of zero is more than relative tolerance, but less than absolute tolerance.

If empty scale shows zero value "+75" and yellow line is on the right side from white vertical line crosses violet boarder of relative tolerance (+65), but doesn't reach red line of absolute tolerance (+100). We may accept new zero:

acceptance of "new zero"

After "new zero" acceptence only boards of relative tolerance move.

Ideal situation: yellow line is absent. Real "zero" value is "0".

ZERO EQUALS "0"
