- Page 4 Range and type of value for output 1 (current loop I1 = symbol „1“on display). Type of value, assigned to output 1, is indicated by displayed unit (here %RH = relative humidity). Upper line displays current value corresponding to measured value (lower line). Here 4 mA corresponds to 0 %RH Press button again to get value for upper point (same output, same value) similarly as at previous point.
- Page 5 Technical parameters: Accuracy data shown are for value displayed on LCD display. For value on analog output is valid too, if selected output range is set inside measuring range. Analog outputs: Two galvanic isolated current loops with range from 4 to 20 mA Current output in case of error: <3.8 mA or >24 mA Power: 9 to 30 V dc, maximum ripple 0.5 % Measuring parameters:...

- Page 7 Error States of the device Device continuously checks its state during operation. In case error is found LCD displays corresponding error code: Error 0 First line displays „Err0“. Check sum error of stored setting inside device’s memory. Output value is < 3.8 mA. This error appears if incorrect writing procedure to device’s memory occurred or if damage of calibration data appeared.
