81 MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.6 RTD RESIST ANCE V ALUES T able 10-4 is a ready reference of RTD resistance values at various temperatures. These are used for test and evaluation of the sensor . NOTE Resistance values are read across the R TD element and are based on the manu- facturer ’s st ated values (±1%).
82 MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.7 W ARNING AND F AUL T MESSAGES The Model 5081-T transmitter continuously monitors the sensor and transmitter for conditions that cause erroneous meas- urements. When a problem occurs, the transmitter displays either a warning or fault message.
MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING Message Explanation See Section OuEr rAnGE Over range, measurement exceeds display limit 10.8.1 SEnSor F AIL Bad sensor , sensor current is a large negative number 10.8.2 CAL Error Calibration error , sensitivity (nA/ppm) is too high or too low 10.
84 MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.8.3 CAL Error At the end of the calibration step, the transmitter calculates the sensitivity in nA/ppm. If the sensitivity is outside the range normally expected, the transmitter displays the CAL Error message and the transmitter does not update the calibration.
MODEL 5081-T SECTION 10.0 DIAGNOSIS AND TROUBLESHOOTING 10.8.7 OFFSEt Err The OFFSEt Err message appears if the zero offset (in mV) exceeds the programmed limit. Before increasing the limit to make the OFFSEt Err message disappear , check the following: 1.

Ein wichtiger Punkt beim Kauf des Geräts Emerson 5081-T (oder sogar vor seinem Kauf) ist das durchlesen seiner Bedienungsanleitung. Dies sollten wir wegen ein paar einfacher Gründe machen:
Wenn Sie Emerson 5081-T noch nicht gekauft haben, ist jetzt ein guter Moment, um sich mit den grundliegenden Daten des Produkts bekannt zu machen. Schauen Sie zuerst die ersten Seiten der Anleitung durch, die Sie oben finden. Dort finden Sie die wichtigsten technischen Daten für Emerson 5081-T - auf diese Weise prüfen Sie, ob das Gerät Ihren Wünschen entspricht. Wenn Sie tiefer in die Benutzeranleitung von Emerson 5081-T reinschauen, lernen Sie alle zugänglichen Produktfunktionen kennen, sowie erhalten Informationen über die Nutzung. Die Informationen, die Sie über Emerson 5081-T erhalten, werden Ihnen bestimmt bei der Kaufentscheidung helfen.
Wenn Sie aber schon Emerson 5081-T besitzen, und noch keine Gelegenheit dazu hatten, die Bedienungsanleitung zu lesen, sollten Sie es aufgrund der oben beschriebenen Gründe machen. Sie erfahren dann, ob Sie die zugänglichen Funktionen richtig genutzt haben, aber auch, ob Sie keine Fehler begangen haben, die den Nutzungszeitraum von Emerson 5081-T verkürzen könnten.
Jedoch ist die eine der wichtigsten Rollen, die eine Bedienungsanleitung für den Nutzer spielt, die Hilfe bei der Lösung von Problemen mit Emerson 5081-T. Sie finden dort fast immer Troubleshooting, also die am häufigsten auftauchenden Störungen und Mängel bei Emerson 5081-T gemeinsam mit Hinweisen bezüglich der Arten ihrer Lösung.
