The device won’t load. What do I do?

If, after pressing the power button, the green LED does not light, connect the device to the AC/DC-adapter from the delivery set and try again in 15-20 minutes.

During start-up the signal from the sensor is “too great/small”.

First of all, check the correctness of the sensor type settings (IEPE, charge or linear) in TestUp software, and the sensor sensitivity. If the problem is still there - no signal, or it is too small, check the integrity of the sensor cable. If the problem has not been solved, check the IEPE power current (in case it is an IEPE sensor) or connect the sensor to a different channel.

There is high noise level on the shaker caused by the product, which is operating on it outside the test range. How do I not take this noise into consideration during control?

If it is Sine test, you should set the “Synchronous detector” control algorithm for the control channel. In case of Random test, select the "in task spectrum" parameter from the drop-down menu “RMS is calculated in…” of the “Control” tab.

Can any problems occur if an antivirus is installed on my PC?

We do not recommend using anti-virus programmes on your PC when working with RL-C21 or RL-C25. As the PC communicates with the devices through the network, the antivirus software may sometimes block data transfer. In case the antivirus software is installed and cannot be deleted, we recommend adding TestUp and the folder, to which it is installed, to the list of antivirus exceptions, or disable the protection.

Are the settings of channels and shakers, which I specify, saved?

The settings are saved to dedicated databases, and, having specified them once, you are able to use them in all tests.

TestUp does not see the device. There is a message saying that the device has not been found.

Check the connection of the Ethernet cable to the device and PC. Check if the device is loading. Another thing to check in case TestUp does not see the device is whether Windows Firewall is enabled and whether there is an antivirus installed. They should be disabled.
