Error Code Details
The temperature display is
LOW or HIGH
Is the Emissivity or E-Slope setting correct?
Is the field of view blocked?
Are reflections or background energy
causing high readings?
The display shows LOW when the measured temperature is below
the Sensor Zero Scale Temperature by a few degrees.
The display shows HIGH when the measured temperature is
above the Sensor Full Scale value by a few degrees.
The display remains LOW or HGH as long as the measured
temperature is out-of-range.
For Sensor Series 5R
Temperature Display is
INV
Note: iALM must be set to ON for this
Alarm condition to be displayed on Sensor
rear panel and for the Alarm Relay to
operate.
This is an Invalid Alarm display. The process measurement
conditions are invalid. The infrared energy reaching the Sensor is
too low to provide reliable temperature measurement.
For Sensor Series 5R
Alarm condition is
pINV
Note: iALM must be set to ON for this
Alarm condition to be displayed on Sensor
rear panel and the Alarm Relay operates.
This is an Invalid Alarm with the Peak Picker On. It is displayed, if
the infrared energy reaching the Sensor is too low to provide
reliable temperature measurements.
Displayed temperature readings are peaked values or hold values
from Peak Picker or Track and Hold signal conditioning.
