4.2 Testing the Balance
The amount of offset with respect to the reference weight can be checked. This is called “span test.”
Performing a span test will not calibrate the balance.
Use a weight for calibration that weighs 50% of the weighing capacity or heavier. To calibrate more
accurately, use a weight that is equivalent to the weighing capacity.
Please contact us if you wish inquire about or place an order for calibration weights.

Weight error = True value – Current weight
When a weight error is more than “0”, the displayed weight is
less than the actual weight.
Press any key to return to normal display.
