FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What is the typical accuracy range for the DOL 104 sensor?

A: Accuracy is typically plus or minus 2 percent RH between 40 to 85 percent RH at 0 to 40 degrees C.

Wiring & Installation:

Q: What is the maximum recommended cable length for the DOL 104 sensor?

A: The maximum recommended cable length is 200 meters using a 1.50 mm2 cable.

Troubleshooting & Compatibility:

Q: What does a flashing red and green light emitting diode indicate on the DOL 104?

A: The flashing light emitting diode indicates the sensor is operating outside the normal range, typically below 10 percent RH or exceeding 95 percent RH.

Replacement & Upgrades:

Q: Is the DOL 104 sensor suitable for applications requiring temperature measurement?

A: The DOL 104 measures only humidity; the DOL 114 model is recommended for humidity and temperature measurement.
