The comparison of actual test systems shows that the technical data of the devices from different manufacturers are similar in many points. And there are specifications where the devices differ to a greater or lesser extent. When evaluating, however, it should always be questioned what this means for the practical use of the devices.

Specifications as a result of development

In some cases, the technical data are much higher than required by the application. And this was not always the aim during development. Rather, some values are just the result of the development, quasi what has come out.

USPs without added value

And there are certainly manufacturers who deliberately work towards generating "unique selling points", which in the end, nobody needs. A real USP only becomes more important when the existing advantages also offer added value and a special benefit for the customer.

Technical data does not tell the whole story

Technical data are easy to compare. But purely numerical values say not much about which product is best suited for the customer. Product features and properties that cannot be evaluated with numbers, or only with difficulty, often lose their importance in the comparison. And it is often here where the advantages can be found that offer real added value for the customer.

Real USPs are not easy to find

The special features of our ARTES testing systems are pointed out in brochures, articles or blog posts. Customers appreciate, for example, that ARTES can be operated in an upright position. The status LEDs in the front or the operation of our devices on DC supplies are also appreciated by many users.

These properties and the many features and functions of ARTES are often not known. For example, the internal control unit, the low-level outputs, the analogue inputs, the multifunctional inputs or the internal GPS synchronisation unit are already included in the standard scope of delivery of the ARTES 600. In competing products, these features are often found, if at all, as options for which a charge must be paid. ARTES also scores points, for example, with its very low noise level, a feature that is difficult to express in numbers.

The software matters

The software plays a major role in relay testing. The device hardware of a test instrument is primarily a freely programmable function generator. Even though ARTES offers much more with its on-site operation, the test software in the end makes a decisive contribution to the high functionality of a professional testing system.

The ARTES 5 software is not only convincing because of its many useful features. It also has the most advanced user interface and the most intuitive operating concept. With ARTES 5, the user reaches his goal faster and easier, and thus saves time. In a following blog post, we will focus on the features and advantages of the ARTES 5 testing software.

ARTES experience live

The special features of ARTES are also highlighted regularly in social media such as Facebook, LikedIn, Twitter or YouTube. However, a live demonstration also offers the opportunity to find out what a customer's requirements and needs are. Only then is it possible to work out the features of ARTES that are important for the customer and to demonstrate their benefits.

Particularly in view of the diverse functions of the software, we are always pleased to offer our customers practical product presentations. Here, the customer not only learns a lot about ARTES, he can also experience ARTES live.

Create ACI codecs yourself....

Enabling users to create their own codecs for their own needs was a requirement we placed on our latest ARTES innovation. The necessary basic knowledge of program development, especially in processing files, is already available to many users. Not much more is needed!

...or have it created by the specialist

Should the required skill be absent or short on time, KoCoS and its partners are ready to help. In cooperative collaboration, the required information and a sample file can be worked out by the user, and the KoCoS specialists will then take care of implementation. The codec created is then included in the standard so that it is available to all users.

Insight into the "secrets" of codec creation

As already described in the previous article, the ACI codec can be used to transfer any settings from an external file into the ARTES 5 software. ACI Codec is a collective term that summarizes different programs, the codecs. A codec is always adapted to a certain format of the source file. Since the source file can have any format, the complexity of the codec generally depends on its structure.


Since a codec maps the parameters of an output file to the parameters of ARTES 5, it is recommended to first define the links in the form of a table. Any necessary adjustments or conversions of the parameters to be read in can also be entered. These are then implemented in the codec itself.

Creation of an Empty Codec

A C#-project can be created automatically from within ARTES 5. This provides methods and properties on the basis of which the ARTES software can be parameterized. The structure of the created project automatically provides the possibility to read any file. 

Assignment of parameters

Since the concept of ACI-Codec is based on the principle of object-oriented programming, the basic structures of ARTES 5 could be mapped as far as possible by the methods and properties. This enables a similar procedure to be followed when creating a codec as when creating a test object in ARTES 5.
To show the basics of creating a codec, static values are assigned to a test object in the following example. For a mature codec, these must be replaced by variables and linked to values in the source file.  
As in ARTES 5, a new test object must first be created. Afterwards the parameters of the test object can be provided with the corresponding values. Depending on the integrated development environment (IDE) used, the Intellisense function simplifies this process considerably.

The created parameter is now assigned values for the "General Information" and "Rated and Limit Values". 

Elements such as functions and the characteristics they contain must be added to the test object in the software interface before values can be assigned, the same procedure is followed in a codec.

Lightweight and compact,

or bigger and heavier than expected?

At first glance, it seems that the ARTES RC3 is the little brother of the ARTES 460 because of the smaller number of inputs and outputs, just extremely robustly packed. It would therefore be expected that the RC3 would also be more compact and lighter than the ARTES 460. According to the specification, however, this is not so.

During the development of the ARTES RC3, high demands were placed on its robustness, reliability and durability. The basis for these requirements was already given with the 4th ARTES hardware generation. This has already proven itself in the ARTES 460/600 and is considered one of the most robust, if not the most robust hardware platform of all relay test systems on the market.

For the integration of the components into the RC3, a specially stable mechanical construction has also been developed inside a hard-shell case. Due to the construction and the robust and resistant hard-shell case, even hard shocks and vibrations have little effect on the RC3.

The dimensions and weight are higher for the first time.  In practice, however, this looks quite different. A relay test system is rarely used in the laboratory or in the workshop. Rather it is transported to the application site. And especially during the transportation the size and the weight are very important. Later during work the test system is moved rather less.

For safe transport, ARTES 460 is equipped with a robust transport box specially designed for this purpose. Inside the box there is a hard foam insert which fits the device and the cable set perfectly and which determines the external dimensions of the box.

Due to its construction in a robust hard-shell case, no additional transport box is required for the ARTES RC3. In comparison, it is a very compact and lightweight system which is very easy to handle in practice. This also makes the ARTES RC3 ideal for demanding outdoor use in rough environmental conditions. Larger and heavier than expected? Rather not.
