Measuring tolerances
These accuracy readings are valid for one year at a temperature of +23 °C (±5 °C) and a relative humidity of less
than 80%, non-condensing.
The accuracy of measurements may be affected when the device is used in a high-frequency electromagnetic field.
The limits are <3 V/m, <30 MHz.
