Measuring tolerances
Accuracy in ±(%ofreading+displayerrorincounts(=numberofsmallestpoints)).Theseaccuracyreadingsare
valid for one year at a temperature of +23 °C (± 5 °C) and a relative humidity of less than 75% (non-condensing).
Temperaturecoefcient:+0.1x(speciedaccuracy)/1°C.
Theaccuracyofmeasurementsmaybeaffectedwhenthedeviceisusedinahigh-frequencyelectromagneticeld.
