High precision weights - class F1:
adjustment, testing and calibration instruments for scales of class II and for quality assurance in accordance with ISO 9001ff for scales with fewer than 300,000 steps. Weights for the calibration and official calibration of weights of the lower classes (M3-F2) in accordance with E08 and OIML R111.
 
High precision weights - class F2:
Adjustment, testing and calibration instruments for scales of class II and for quality assurance in accordance with ISO 9001ff for scales with fewer than 100,000 steps.
 
Weights for the calibration and official calibration of weights of the lower classes (M3-M1) in accordance with E08 and OIML R111. Use for significant business (e.g. precious metals and stones) on scales of class II. Load cells for the depiction of the most precise pull, pressure or torsion conditions.
 
Marking
Weights of 1g and higher are only marked with their nominal value, without information on the unit. Class 2 weights are also marked with the letter ‘F’ above the nominal value. In order to differentiate between them multiple weights with the name nominal value in sets are marked with dots or stars.
 
It is also possible to add up to 5 user properties (symbols, letters and numbers) in order to clearly identify the weights as test or measurement tools. These user properties can be determined by the client when he places the order.
