Touch-trigger probes for CNC milling machines usually use wireless communication in the radio or IR band. Additionally they enable triggering signal filtering in order to avoid false triggers of the probe. These solutions cause a delay in trigger signal transmission from the probe to the machine tool controller. This delay creates an additional pre-travel component, which is directly proportional to the measurement speed and which is the cause of a previously observed but not explained increase of the pre-travel with the increase of the measurement speed. In the paper, a method of testing the delay time of triggering signal is described, an example of delay time testing results is presented and the previous, unexplained results of other researchers are analysed in terms of signal transmission delay.

Introduction - The SARS-CoV-2 pandemic is a major health crisis modern world has to counter. Due to the highly contagious nature of this virus and the rapid growth of infections in many countries specific medical recommendations have been formed to reduce spread of the virus. Aim of the study is determine the psychosocial factors related to obeying medical recommendations against SARS-CoV-2 pandemic during the stage of increasing government’s restrictions and limitations.
Method – The study included 319 participants (261 women and 58 men) aged 18-66 yrs (M=25). The study was carried out via the Internet from 21st March, 2020 to 27th March, 2020. The sample group included participants chosen using “snowball” effect.
Results - It has been shown that the higher anxiety of falling ill, the higher tendency to obey health behaviors towards SARS-CoV-2 (r = .13, p < .001). In order to explain what factors undertaking health behaviors towards SARS-CoV-2 depends on, structural equation modeling was applied including HMB model variables. It has been shown that the benefits and barriers have a significant impact on compliance with health behavior towards SARS-CoV-2 (ß = 0.45, p <0.001).
Conclusions – At the beginning of a pandemic, while increasing restrictions perceived barriers and perceived benefits of obeying health recommendations are significant for explaining health behaviors towards SARS-CoV-2 pandemic. Perceived risk is less important. Higher intensity of health anxiety, understood as a fear of infection (likelihood of illness) is related to obeying the health behaviors towards SARS-Cov-2.
