acceptable error level
There can be no set value. An acceptable level of sampling error for a company making high precision machine parts is likely to be very different from the sampling error for household incomes, for example.
i think between 1% to 5% is acceptable
It is 48.5
A 5P20 CT has a guaranteed error of less than 5% at 20 times it's rated current (in this case 5A, so at 100A), when it's secondary burden is at it's nominal VA rating. The acceptable ratio error has to allow the CT to perform within these bounds to be declared a 5P20 CT.
CODE 23** Indicates that the air temp sensor input is below the minimum acceptable voltage or sensor input is above the acceptable voltage.
The percent error is calculated by taking the absolute difference between the observed value and the accepted value, dividing by the accepted value, and then multiplying by 100 to express it as a percentage. It is used to determine the accuracy of experimental results.
Undefined: You cannot divide by zero
Old type, analog power factor meters may be considered 2% instruments.
Abnormally high print head temperature. Check environment if acceptable replace print head.
It is + and - 5 %. To draw any conclusion the observations should be made very critically and analyzed statistically.
