What to do if Xentaur Transmitter display shows OPN?
- W
  williamsonjamesAug 4, 2025
  If your Xentaur Transmitter's display shows 'OPN', consider these potential causes: 1. **Instrument Failure:** Short the SIG and SHIELD contacts of the sensor input terminal. If the instrument displays 'SHR', the problem lies in the cable or sensor. Otherwise, return the instrument for service. 2. **Open Circuit on Cable:** Disconnect the cable from the sensor and short the center pin of the plug to the outer shell. If the display still shows 'OPN', repair the cable. 3. **Open Circuit on Sensor:** Check the sensor connection or replace the sensor.

Why is my Xentaur XDT reading wet?

  A wet reading on your Xentaur Transmitter could be due to a leak in the system or the use of unsuitable piping. To resolve this, fix any leaks present or replace the unsuitable pipe with copper or stainless steel. For flexible connections, use PTFE pipe and avoid rubber or plastic pipe.

Why is my Xentaur XDT response slow?
- E
  erica73Aug 13, 2025
  A slow response from your Xentaur Transmitter may be due to several factors. While section 2.3 and sample pipe material are mentioned, bleeding a sample gas at atmospheric pressure through the sensor sampling chamber using 1/8” (3mm) o.d. sample pipe is generally more effective. The causes could be: 1. Water vapor in the system. 2. Flow rate too low. 3. Sample pipe too large and/or too long. 4. Unsuitable sample pipe. 5. Leaks. 6. Hygroscopic materials in the sample system.

What does SAT mean on Xentaur Transmitter display and how to fix it?
- S
  Stephanie SmithAug 19, 2025
  If the display on your Xentaur Transmitter shows 'SAT', it indicates prolonged exposure to wet gas. To resolve this, dry down the sensor. You can achieve this by installing the sensor in a known dry gas stream, such as instrument quality air or dry nitrogen. Alternatively, place the sensor in a dry container or bottle with desiccant and seal it from outside air. The shipping container is designed for this purpose.

  A dry reading on your Xentaur Transmitter could be due to a wrongly set SpanCheck™ or a faulty sensor. Verify SpanCheck™, or return the sensor for full calibration to your representative.
