Table 18 Signal Description

RTD Connections

JY-6311 can support 2-wire, 3-wire or 4-wire RTD connection.

2-Wire RTD connection

When using a 2-wire RTD configuration, user needs to connect the RTD signal to Ex+ and Ex- terminal of current excitation as shown in Figure 3. Due to the presence of lead wires resistance, this type of connection may introduce large measurement errors, which are related to the material of the lead wire. This type of wiring is not suitable for high precision temperature measurement needs.

3-Wire RTD connection

In a 3-wire RTD configuration, the Ex+ and AI- terminal will output two precision current excitations to the RTD sensor and flow back through the Ex- terminal as shown in Figure 4. Since the voltage generated by the wire resistance connected to the Ex+ terminal and the voltage of wire resistance connected to the AI- terminal will cancel each other out, this type of connection effectively eliminates the effect of wire resistance, but in practice, it is difficult to match the resistances of the two wires exactly, so there will still be some degree of mismatch error

4-wire RTD connection

In a 4-wire configuration, the Ex+ terminal will output a 1 mA excitation current which flows back to the Ex- terminal and measures only the voltage of the RTD as shown in Figure 5.Since the current loop of the leads is independent of the voltage measurement circuit, there is no error due to lead resistance.

Resistance Measurement Accuracy

This chapter provides the voltage accuracy specifications of JY-6311

Gain and Offset Error

JY-6311 measures RTD resistance. It has built-in filters to improve the measurement accuracy of JY-6311 accuracy is defined by:

Accuracy = Gain Error (% of reading) + Offset Error (mΩ).

It should be noted when the reading is close to zero, the gain error is very small and negligible, the offset error is dominant; when the reading is getting close to the full range, the gain error becomes more significant.

Basic Resistance Accuracy

The basic RTD measurement accuracy is shown in Table 19.

Please refer to 4.3 for more information on 2,3 and 4-wire RTD connections.

Example of Calculating Gain and Offset Errors

Table 20 shows two examples of calculating the total gain and offset errors. Select the sample rate of 40 S/s and the range of 400 Ω.Then get two different measurements.The first one has a reading value of 100 Ω, while the second one has a reading value of 400 Ω. For the 100 Ω reading value, the gain error is 3 mΩ, while for the 400 Ω reading value, the gain error is 12 mΩ.The offset errors for both reading values are the same 28 mΩ.As a result, For the 100 Ω reading value, the total error(Gain+Offset) is 31 mΩ, while for the 400 Ω. reading value, the total error(Gain+Offset) is 40 mΩ.

Total Error (Gain+Offset)(mΩ)	31		40

Temperature Measurement Accuracy

The temperature measurement is converted from the resistance measurement. Table 5 lists the temperature measurement accuracies for different wire configurations

RTD Type	Temperature Range (℃)	24H Temperature Measurement Accuracy (4-Wire) (℃)	90Days Temperature Measurement Accuracy (4-Wire) (℃)
PT 100	-200 to 850	0.11	0.27
SampleRate = 40/400/800 Samples/second

RTD Measurement Basics

A platinum resistance temperature detector (RTD) has a typical resistance of 100 Ω at 0 °C. Its resistance varies with temperature, and it can typically measure temperatures up to 850°C. A RTD can be used to measure temperatures up to 850°C. It can also be used to measure temperatures up to 850°C. Letting current flow through the RTD produces a voltage across the RTD. By measuring this voltage, its resistance, and therefore its temperature, can be determined

This resistance is measured by JY-6311 and is then converted the temperature values using a conversion formula defiend by the standard.

RTD Accuracy

A RTD has its own accuracy, also called error tolerance in many international standards. Table 22 shows the accuracies of common RTD according to standards

The accuracies given by Table 22 are valid for unused RTD material only. It is important that users verifythe accuracy of the RTD from the RTD manufacturer.

Temperature Measurement Accuracy by JY-6311

A RTD converts a temperature reading to a voltage which is then measured by JY-6311. The standard provides the conversion formula for different thermocouples and for different temperature ranges. Table 21 shows the temperature measurement accuracy using JY-6311 for each type and each range of RTD . The operating conditions are also listed in the table.

Total Temperature Measurement Accuracy

The total temperature measurement accuracy consists of the errors due to the RTD and measurement errors by JY-6311 as shown in Figure 6. It can be calculated by:

Err1 is the RTD error from Table 22 of Section 4.5.2. Err2 is the temperature measurement accuracy from

Table 21 of Section 4.5.3.

Table 23 shows two calculations for the total accuracies when using a IEC Class A RTD to measure 100º C and 800ºC temperatures with 40 S/s sample rate. The two temperatures fall into different range. Hence the temperature measurement errors by JY-6311 are different.

Total Temperature Measurement Error (PT 100)
Sample Rate (Sample/s)	40
RTD Type and Class	PT 100	PT 100

System Software

When using the JY-6311 in the Windows environment, you need to install the following software from the Microsoft website:
Microsoft Visual Studio Version 2015 or above,

NET Framework version is 4.0 or above.
NET Framework is coming with Windows 10. For Windows 7, please check .NET Framework version and upgrade to 4.0 or later version.

Given the resource limitation, JYTEK only tested JY-6311 be with .NET Framework 4.0 with Microsoft Visual Studio 2015. JYTEK relies on Microsoft to maintain compatibility for the newer versions.

C# Programming Language

All JYTEK default programming language is Microsoft C#. This is Microsoft’s recommended programming language in Microsoft Visual Studio and is particularly suitable for test and measurement applications. C# is also a cross platform programming language.

JY-6311 Series Hardware Driver

After installing the required application development environment as described above, you need to install the JY-6311 hardware driver JYTEK hardware driver has two parts: the shared common driver kernel software (FirmDrive) and the specific hardware driver. Common Driver Kernel Software (FirmDrive): FirmDrive is JYTEK’s kernel software for all hardware products of JYTEK instruments. You need to install the FirmDrive software before using any other JYTEK hardware products. FirmDrive only needs to be installed once. After that, you can install the specific hardware driver. Specific Hardware Driver: Each JYTEK hardware has a C# specific hardware driver. This driver provides rich and easy-to-use C# interfaces for users to operate various JY-6311 function. JYTEK has standardized the ways which JYTEK and other vendor’s DAQ boards are used by providing a consistent user interface, using the methods, properties and enumerations in the object-oriented programming environment. Once you get yourself familiar with how one JYTEK DAQ card works, you should be able to know how to use all other DAQ hardware by using the same methods. Note that this driver does not support cross-processing, and if you are using more than one function, it is best to operate in one process.

Install the SeeSharpTools from JYTEK

To efficiently and effectively use JY-6311 boards, you need to install a set of free C# utilities, SeeSharpTools from JYTEK. The SeeSharpTools offers rich user interface functions you will find convenient in developing your applications. They are also needed to run the examples that come with JY-6311 hardware. Please register and download the latest SeeSharpTools from our website, www.jytek.com.

Running C# Programs in Linux

Most C# written programs in Windows can be run by the MonoDevelop development system in a Linux environment. You would develop your C# applications in Windows using Microsoft Visual Studio. Once it is done, run this application in the MonoDevelop environment. This is JYTEK’s recommended way to run your C# programs in a Linux environment. If you want to use your own Linux development system other than MonoDevelop, you can do it by using our Linux driver. However, JYTEK does not have the capability to support the Linux applications. JYTEK completely relies upon Microsoft to maintain the cross-platform compatibility between Windows and Linux using MonoDevelop.

Calibration

JY-6311 Series boards are precalibrated before the shipment. We recommend you recalibrate JY-6311 board periodically to ensure measurement accuracy. A commonly accepted practice is one year. If for any reason, you need to recalibrate your board, please contact JYTEK.

Using JY-6311 in Other Software

While JYTEK’s default application platform is Visual Studio, the programming language is C#, we recognize there are other platforms that are either becoming very popular or have been widely used in data acquisition applications. Among them are Python, C++, and LabVIEW. This chapter explains how you can use a JY-6311 DAQ card using one of these software.

Python

JYTEK provides and supports a native Python driver for JY-6311 boards. There are many different versions of Python. JYTEK has only tested in CPython version 3.5.4. There is no guarantee that JYTEK Python drivers will work correctly with other versions of Python. If you want to be our partner to support different Python platforms, please contact us.

C++

We recommend our customers to use C# drivers because C# platform deliver much better efficiency and performance in most situations. We also provide C++ drivers and examples in the Qt IDE, which can be downloaded from web. However, due to the limit of our resources, we do not actively support C++ drivers. If you want to be our partner to support C++ drivers, please contact us.

LabVIEW

LabVIEW is a software product from National Instruments. JYTEK does not support LabVIEW and will no longer provide a LabVIEW interface to JY-6311 boards. Our third-party partners may have LabVIEW support to JY-6311 boards. Wecan recommend you if you want to convert your LabVIEW applications to C# based applications.
