Frequently asked questions and problems

Our experience is our greatest asset, so we collect frequently asked questions for our users and answer them publicly, so you always have our answers at your fingertips.

Question 1: PROGRAMMING A DATA LOGGER – how do I read and program the ebro data logger?

The data logger is read and programmed using the WINLOG software, which can be found at this link.

After installing the software, run the software. Insert the Logger into the interface or into a USB socket and follow the steps in the video.

Question 2: I forgot my password for WINLOG software, what should I do?

Question 3: SETTING UP THE CONTROLLER – we have bought a controller, how do we set it up (configure it)?

In most cases, the set-up of the controller is done at the time of purchase, if the user provides the set-up parameters (input, control, alarm operation).

Otherwise, the user can also set (configure) the controller himself. To start, you need to configure the input type on the controller, which you choose according to what you want to connect. If you connect a TC thermocouple (K, J, R, S, B, E, T, N) to the controller, you must select the correct terminals, marked TC on the controller diagram. If you connect a RTD temperature sensor (PT100) to the controller, select the terminals marked RTD on the controller schematic. Connect the analogue input (voltage or current) to the terminals marked DC V (for voltage input) or DC AV (for analogue current input).

After configuring the input type, select the alarm type and specify the operating type of the temperature control.

Question 4: The temperature of the SHINKO controller fluctuates, how do we calm it down (AT)?

By default, SHINKO controllers have default values for PID parameters, which are essential for accurate temperature control.

As the PID parameters are different for each system, it is necessary to enter or read them correctly.

With the AT or Auto-Tunning function, which all SHINKO controllers have, you can easily achieve precise regulation. You can start the AT function in the menu for setting the control parameters. After starting the AT function, the controller will repeat the heating and cooling process three times.

Other settings cannot be changed while the AT function is running. The operation of the AT function is indicated by a signal on the display (flashing orange AT symbol).

Question 5: CONNECTING THE TENSOR – how do I connect the temperature sensor?

To connect a temperature sensor, you need to know which type of sensor it is.

Thermocouple connection (TC)

The most important thing for the correct connection of the thermocouples to the system is the use of the appropriate thermocouple compensation cables. The cable must be of the same type as the thermocouple, see table.

  • *Unofficialsymbols or standards (withdrawn standards).
  • *The types shown are cards. The card is accompanied by a complement C for the compensation cable (e.g. NC is a compensation cable for type N) or complement X for the thermo cable (e.g. KX is a thermo cable for type K). Within the standard, the -X or -C versions sometimes differ in colour).

Connecting RTDs (Resistive Temperature Detectors)

Use copper conductors to connect the resistive sensors to the system. We recommend a 3 or 4 wire connection.

Question 6: We have a data logger. We have replaced our computer and don’t have the correct software loaded. How to proceed?

EBRO Logger EBI 20 and EBI 3×0 series

All you need to do is download the new software Winlog. basic which you can access HERE.

Brief instructions before using the EBI 20 logger for the first time: HERE

EBRO Logger EBI -10/-100/-11/-12 series

To set up and read these loggers, you have purchased one of the paid Winlog programs Winlog .light,,, Winlog.wave, Winlog.validation or Winlog.web.

These strips are licensed, which means they are not freely downloadable from the website.

When you start the program, you will see the license number (serial no.) of the program, which is made up of several characters (which can be numbers and/or letters) in roughly the following format (it is different each time):


Please forward this number to our contact and we will help you further.

Question 7: DISTANCE CANCELLATION – why is it necessary to perform a sensor correction when connecting a new sensor to a thermometer?

A digital thermometer is a meter that consists of a sensing (sensor) part and a digital display. Simpler thermometers are “all in one” and the sensor part cannot be separated (swapped). However, high-tech digital thermometers often have sensors in the form of a temperature sensor with a connector, allowing the sensor to be changed in case of failure or multiple sensors to be used with one thermometer. In these cases we have to deal with two accuracies, one for the sensor and one for the thermometer. In practice, most users only follow the technical specification of the thermometer, which is no longer valid after the sensor has been replaced, resulting in erroneous measurements and inconsistencies with established measurement procedures.

Digital thermometers are designed for higher accuracy measurements, and few people are satisfied with a tolerance of 1 °C or more. Therefore, the thermometer sensor needs to be calibrated – i.e. part of the error contributed by the replaced sensor needs to be corrected. Whether or not this is enabled depends on the thermometer manufacturer, but most technology thermometers do. It should be remembered that the thermometer was probably calibrated with the original sensor when purchased, and the actual sensor error values themselves are never known to the actual user later on by the meter manufacturers, unless such a separate specification is requested at the time of ordering, as e.g. calibration laboratories.

The correction of the deviation shall be carried out by means of a calibration procedure and at the precise calibration points specified by the thermometer manufacturer (manufacturer’s protocol), to a correction of 0 (zero) or the minimum value according to the thermometer specification. This achieves the key objective of eliminating the bias, which is that the user does not need to take the correction into account in the normal use of the thermometer, as it is negligible. For everyday use it is very important and practical not to have to take into account the correction of the display for each measurement. This makes the work faster and more reliable in terms of measurement results. Although the correction of the deviation is performed by calibration, it is not a calibration service in the classical sense, since the correction of the deviation is a matter of the manufacturer’s protocol and calibration points, but it can be part of the preparation for a user-required calibration if they are performed in sequence.

The deviation correction service should be carried out by a reliable provider, preferably an accredited laboratory, before the first use or after a change of sensor and/or before recalibration. Unprofessional implementation of the correction of a deviation often increases the error, which is why professional bodies and meter manufacturers alike often do not approve/enable user correction of the error. However, for those meters that do, great care is needed in the implementation of such fault correction, taking into account the contributions and risks involved.

In the case where several temperature sensors are used with one meter, we usually do not perform deviation correction with any of the sensors. Then both errors, the thermometer error and the sensor error (which must be known and added together), must be “manually” taken into account. If you were to correct for the bias with just one sensor and use other sensors, you would increase the measurement error of all the other sensors. This is something to pay close attention to.

The ELPRO Calibration Laboratory and the ELPRO ebro Authorised Service Centre carry out deviation correction for the entire ELPRO range of portable temperature sensors in combination with ebro thermometers and other measuring instruments such as dataloggers, etc.
