I work in the scale industry. Instruments that we test generally have a digital readout, expressed in decimal units. Ocassionally, we will happen upon an older or lower precision instrument whose readout is expressed in fractions (for example, 1/4 lb increments). This could be a dial type indicator (like the scales at the fair where the guy guesses your weight) or a beam type scale such as you typically see in doctor's offices.
Is it proper with this type of indicator to write the test result using decimals? Our software doesn't like fractions, but I feel that writing "0.5" instead of "1/2" implies a level of precision that doesn't exist. Does 17025 address this issue?
