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 coefficient applies outside of this temperature range: +0.1 x (specified accuracy)/1°C.
The measurement can be impaired when the device is operated within a high-frequency electromagnetic field 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 specified and may cause wrong displays.
