# The Non-automatic Weighing Instruments Regulations 2016, Paragraph 4.1


On implementation of the procedures laid down in regulation 36, the error of indication shall not exceed the maximum permissible error of indication as shown in Table 3. In the case of digital indication the error of indication shall be corrected for the rounding error.
The maximum permissible errors apply to the net value and tare value for all possible loads, excluding preset tare values.
