Measurement tolerances
Statement of accuracy in ± (% of reading + display error in counts (= number of smallest points)). The accuracy is
valid for one year at a temperature of +23 °C (±5 °C), and at a relative humidity of less than 75%, non-condensing. A
temperaturecoefcientappliesoutsideofthistemperaturerange:+0.1x(speciedaccuracy)/1°C.
Themeasurementcanbeimpairedwhenthedeviceisoperatedwithinahigh-frequencyelectromagneticeldstrength.
In an electromagnetically burdened environment up to 1 V/m, the accuracy increases by 5% of the measured value.
Theareaabove1V/misnolongerspeciedandmaycausewrongdisplays.
