Intensity Testing Accuracy Testing
For Max.permissible tolerance see the table, if the length is within the minimal division value.
The Max.permissible tolerance is calculated as per the following formula,if the length is bigger than the minimal division value:
     △---Max.permissible tolerance in mm.
     △=±(1.2+0.8L)
L-Length value, The bigger and most approx . Round-numbered value in meter is taken in case a measured length is less than a round-numbered multiple of one meter. The permissible to combined measuring tool is used.
