Calibration Information

Specifications

Accuracy is specified for 1 year after calibration, at operating temperatures of 18 °C to 28 °C, with relative humidity

at 0 % to 90 %. Accuracy specifications take the form of: ±( [ % of Reading ] + [ Counts ] ). AC conversions are

ac-coupled, true rms responding.
