Answers to questions, perhaps not covered by existing documentation:
Q. What is "Advanced Peak Hold" in Endurance?
A. Advanced peak hold can be thought of as an infinite peak hold with a reset based on the transition from to under to over, through the threshold value.
Q. When I engage video sighting I see a very small temperature reading increase (0.5°C @ 1800°C), is this normal or an addressable problem?
A. When the video output stream is enabled, the microcontroller utilization increases for the video stream compression (MJPEG). This causes a small increase in microcontroller temperature and a kind of thermal shock. It should be remembered that this deviation is far inside the specification of the sensor and is considered an effect, not a defect. It is expected that after a time the reading will return to the previous level. For critical applications it is advised to set the average time to the maximum appropriate value for the application. The expectation is that this effect (0.027% change in reading) will not be experienced or noticeable on other models.
Q. My E1R or E2R Endurance sensor is not providing a temperature reading in 2 color mode. The display reads EUUU and and there is a temperature value for the 1C reading.
To achieve reliable measurements at the lower end of the sensor’s range, it’s essential to work with an object that has a combined emissivity/transmissivity factor at least 0.45 (equivalent to 55% attenuation).

Q. How do I unlock the switch panel.
A. Navigate to KEY-ENTER and hold enter key for 10s See Article
Q. I have an E3ML, it should display EUUU but is showing 54°C/192.2°F
A. If the sensor does not return to EUUU when covering the lens, return for recalibration.
Q. Is that possible to update firmware in Endurance via RS485 communication?
A. Yes, firmware can be updated via RS485 communication. It will take 20-30% longer time compared to Ethernet communication but the update is possible.
Q. What is the latest firmware revision
A. 2.02.35 (older hardware) and 2.03.11 (newer hardware), both versions in one files. Pre-release candidate with a fix for an intermittent mA output offset. Please create ticket if you need a copy of this firmware New Ticket
For internal use the firmware can be downloaded from here Firmware Pre-Release Candidate
Q. What is the latest production firmware revision
A. 2.02.34 (older hardware) and 2.03.10 (newer hardware),both versions in one files
Q. I have an E1RL and when I set it to 1 color mode to measure from 550° Celsius, I cannot get any analog signal below 600° Celsius?
A. This is because the sensor is shipped with the analog scaling set to the range that covers the operation of the model number. As the sensor is a ratio or two-color sensor, the analog output scaling starts at 600° Celsius . You need to change the scaling to match the output range you need. See Article for futther explanation.
Q. Can the dual power inputs provide some form of PSU redundancy?
A. The short answer is "Yes, but with caveats as redundancy was not part of the design specification". Please see article for further information See Article
Q. Are there any web browsers that are not working with the web server page?
A. Microsoft Internet Explorer can freeze and not update data. Chrome, Edge, Firefox etc all work without issues.
Q. Is the analog output able to be calibration and adjusted independently of the temperature reading?
A. Yes, this is a unique feature of the Endurance sensor See Article
Q. Is there any comprehensive guidance for calibration of the sensor?
A. Yes, we have a single article with guidance and links to further articles See Article
Q. What are the available Protocols in Endurance?
A. The Endurance series has ASCII on RS485 and HTTP Ethernet. In addition, it does have Profinet IO and EtherNet/IP
Q. Under what circumstances would I enable the SF parameters (Sample Filter)?
A. If you have what may be described as spurious measurement spikes using a ratio (2C) sensor when you have a very fast changing energy in the application. The filter looks at the transient signal over a number of internal samples and will define a change that is too fast as invalid.
Q. The relay is specified at 48V/300mA - is this DC and or AC?
A. DC only
Q. What happens to the mA signal if the loop impedance exceeds 500 ohms?
A. The analog output accuracy remains in specification up to a total loop impedance of 610 ohms. Beyond this has not been tested but it is reasonable to assume that the signal will drop more or less proportionally up to the maximum theoretical loop impedance based on a measurement of the voltage of the mA output (also not tested). No damage will result by exceeding the loop impedance.
Q. Can I use the PoE adapter from the ThermoView sensor?
A. No. Further information can be found here: PoE Comparison
Q. The serial number on the label is not readable, but the MAC address and model number is. How can I find the serial number.
A. The serial number is visible in the software and also on the rear LCD display on the information menu next in the list after the MAC address. If it is not possible to use the display or software (defective unit) we can cross reference the MAC address and serial number in our production database. Please open a new ticket for this enquiry, we aim to provide the information within 24 hours.
Q. With an E1R or E2R how can I evaluate the stability of the set slope value
A. Using DatatempMultidrop you can observe the two single wavelength temperature readings (wide band and narrow band). The emissivity cannot be set individually for each wavelength, but in a process evaluation, if the wide and narrow band 1C readings are equal, you can work with a slope of 1. You can also determine that the slope value is not stable. In this case the difference between wide and narrow band readings should be fairly consistent over time or temperature. If this is not this case further testing will required. For example dynamic slope adjustment (via analog input or PLC) or consideration that the slope value is only valid for a small measurement window (setpoint).
Q. Is Endurance compatible with a Raytek MM or Ircon Modline 7 Thermojacket
A. Yes, but you will need the nose cone adapter (Item number 2494113) plus the Endurance extraction tool (E-TJET Item number 486752).
Q. Can the Endurance under and over range mA values be customized, like with Modline 5? Typically this would be for under range behavior to define 4mA so a control system does not interpret the 2-3mA as a cable break.
A. Yes, since firmware revision 2.02.18 (July 2017) it has been possible to set non default under and over range mA values via the ASCII command ALO (under range) and AHO (over range). This parameter is adjustable using DTMD v6 or via an terminal program.
Q. Does the sighting reticle (center circle in thru-lens sighting) show the spot size when the unit is defocused?
A. No. For example, with the focus set closer than the actual distance the reticle will be smaller than the spot size. The reticle size is optimized for when the unit is focused.
Q. Does the sighting LED sighting show the spot size when the unit is defocused?
A. Yes, spot sizes in all focus setting and at all positions are indicated
Q. What is are wavelengths of the two bands in an E1R sensor?
A. Wide band (top) 0.75-1.1um. Narrow band (bottom) 0.95-1.1um
Q. Are the specific wavelengths available for other Endurance sensors?
A. Yes, but only supplied on demand as these are not published values. Please raise a tech' support ticket.
Q. What is the min/max emissivity setting?
A. 0.1 to 1.1
Q. What is the min/max slope setting?
A. 0.85 to 1.15
Q. What signal is needed for remote adjustment of emissivity or slope?
A. 0-20mA or 4-20mA. Selectable in software or on rear panel of sensor
Current Input Mode or ASCII command INM=0 and INM
Q. Can the emissivity or slope scale be adjusted?
A. No
Q. Is there a lookup table for emissivity/slope and corresponding mA value available?
Q. Can the remote ambient temperature compensation be scaled?
A. Yes - usually to match the IR sensor used to measure the ambient reflection.
Q. How many video streams are possible concurrently?
A. 2 streams are possible. This can be any combination of DTMD, Web Server or Streaming Link.
Q. To which standard do we test repeatability to:
A. We use the test method described in IEC/TS 62492-2 section 5.14 and VDI/VDE 3511 Part 4.3 section 5.3.
Q. How does offset and gain affect the reading - is it on the energy or the temperature reading?
A. The offset and gain applies to the calculated temperature reading only and not the detector energy.
Q. In a ratio version is it possible to adjust (calibrate) the 1C and 2C readings separately?
A. Yes, since firmware fw2.02.29 the wideband reading (1C) and the 2C readings have separate offset and gain parameters.
Q. What is the minimum data burst time interval?
A. 5ms
Q. Can this data transfer be improved on?
A. Not via burst. It is possible to poll a single command like ?T without interval and response close to 2ms (specification not guaranteed and reliant on a number of factors).
Q. What are the dimensions of the sapphire windows used in E-FB1 (standalone screw on protective window) and E-FORFQP (two piece quick release window and air purge collar set)?
A. Diameter 15.88mm (0.625"), thickness 2mm (0.079").
Q. How does "Field Calibration" work with Endurance and industrial protocols?
A. Offset and gain values can be defined in the initialization parameters in the respective project. If the sensor has non-default offset and gain values set before installing into an industrial protocol system, care is needed to ensure that these offset and gain parameters are matched in the project, otherwise the standard values will overwrite the set values. As these values are defined only as initialization parameters, it is not possible to adjust these incrementally or "on the fly" like emissivity or transmissivity.
Q. How does "Field Calibration" work with Endurance?
A. The field calibration function in DTMD v6 is a tool built in to the software for calculating and updating the standard offset and gain parameters (DO and DG) in the device. 1 point (offset) and 2 point (offset and gain) options are available. After running through the steps of the routine, the offset and gain values are uploaded to the device). These parameters can further be adjusted incrementally via the parameter list.
Q. How does "Field Calibration" work with Endurance - is it possible to adjust the 1C and 2 readings separately?
A. Yes, the 1C (wide band) temperature reading is adjusted by the command DOT device offset top (wafer) and DGT device gain top (detector). The wide band detector sits above the narrow band detector. The narrow band temperature reading is not possible to calibrate in the field as it influences the basic 2C temperature calculation. From software revision 6.1.4 the field calibration routine offers both types of calibration.
Q. Can Endurance sensor be installed directly inside vacuum chamber?
A. It is not recommended to install Endurance directly inside of a vacuum chamber.
Chamber should have viewport with IR-suitable window (like for 2M quartz window) through which the Endurance can measure the target.
Q. Why does Endurance web browser show "503: Service Unavailable" when I type in the sensor IP address?
A. Utilizing the DTMD 6.1.x software, the Web Server feature located in the Settings tab must be set to value 1 or "On". The factory default value is 0 or "Off".
Q. Are there any web browsers that are not working with the web server page?
A. Under evaluation March 2023 - Chrome, Edge, Firefox all known to work but a thought that MS IE does not - will be double checked,
