Accuracy adders for use in RF Fields: In an RF field of

3V/m, change the accuracy specifications as follows:

For DC Millivolts Measrement, add 0.03% of range

For AC Volts Measurement, add 0.37% of range

For DC Current Measurement, 30.000 mA range, add

0.14% or range

For DC Current Output, add 0.02% of span

Accuracy for all meter functions is not specified in RF

fields > 3V/m.

Relative humidity: 95% up to 30°C, 75% up to 40°C,

45% up to 50°C, and 35% up to 55°C
