Customer Testimonials
Frasohn Elektronische Gerätebau — GmbH is a manufacturer of high-voltage devices for electrostatic filter systems. These devices have a steel boiler, which contains, among other things, the high-voltage transformer, which is filled with insulation oil. We weld the boiler ourselves with a welding robot and it must be 100% tight.
This can only be achieved with a perfect weld seam. We use the ZIS calibration unit to measure the ToolCenterPoint (TCP) on our welding robot. As a result of this precise determination, we were able to significantly improve the quality of the welds.
The ZIS calibration unit is characterized by its ease of use. Measuring the TCP with it is very easy and makes work much easier. For us, the ZIS calibration unit is an investment that has paid off.
ZIS Indurstrietechnik GmbH is a reliable partner for order processing and technical support and we can only recommend them and their products!

We use the ZIS TCP Calibration Unit to teach, track, and benchmark our Fanuc LR Mate robots. We are a small manufacturer of medical and orthopedic models and use the robots to make precision cuts and holes in medical models. This requires the highest possible accuracy when setting the TCP.
The ZIS calibration unit is a very easy tool to learn and use. It features “X”, “Y” “Z” LED position indicators. The measured values can be transferred via the WiFi interface to the supplied “RobCal” software, where they can be analyzed and logged.
It also has a.dxf diagram of each of the axis movements, which is extremely useful for comparing the movement for future references. The ZIS device comes in a very nicely padded wooden case that securely houses the device and all accessories.
I think the ZIS Calibration Unit is definitely worth the investment we've made. The device allows us to calibrate the TCP in a precisely controlled manner and thus enables us to increase the accuracy of our robots.

Robot Calibration Unit FAQ
Robots are sequential kinematic structures with 6 drives arranged one behind the other. Because of this kinematic structure, a robot must move all 6 drives to achieve a simple linear movement.
Only the robot itself is delivered by the manufacturer; tools and clamps are then installed by system houses and users. In order for a robot to learn the necessary geometry of these tools, the TCP must be measured and the axes must be set to zero. This is called calibrating the robot.
TCP or Tool Center Point is the robot's tool or tool coordinate system. With a MAG torch, the tool center point is, for example, in the wire tip. Geometrically, the TCP or Tool Center Point represents the offset vector from the robot's flange coordinate system to the tool or tool coordinate system. In addition to axis calibration (setting the zero position of the robot's 6 drive axes), the measurement of the TCP is a prerequisite for exact robot calibration.
The TCP (Tool Center Point) can be measured using various variants:
- Multi-point calibration
With the TCP, the robot approaches the same point in space in various positions. The number of positions required depends on the type of robot used (KUKA 4 positions, FANUC — 3 or 6 positions). The robot automatically calculates the TCP based on these positions. - Measured tool
The tool is absolutely measured on an external device and the TCP values are manually transferred to the robot as coordinates.
In order to display various tools, the robot controllers allow various TCP values to be stored. When you select a tool, the associated TCP vector is also activated.
In practice, robotic measurement is associated with many difficulties for users. The ZIS robot calibration unit simplifies the measurement of the robot and allows user-independent repeatability. The following functions are supported for industrial robot calibration:
- For multi-point calibration, the calibration unit works like an electronic tip. The LED displays on the top show the user exactly how to move the robot to reach the starting position.
- With the help of the “RobCal” software, the device can be connected to a laptop via WiFi. By pivoting around the TCP, the accuracy of the calibration can be checked and recorded.
The data recorded by “RobCal” can be reused in the following form:
- Basis for calculating the robot's accuracy within the “RobCal” software by calculating the TCP deviation in the 3 main levels
- Saving as DXF format for further use/evaluation in a CAD system
- Printout of TCP accuracy in a PDF protocol for documentation to customers or for archiving.
