'Wet' snow vs. 'dry' snow. The size and make up of a snowflake depends on how many ice crystals group together and this will be determined by air temperatures. Snowflakes that fall through dry, cool air will be small, powdery snowflakes that don't stick together.
Calibration Services. NI offers high-performance hardware and is committed to helping you maintain that performance for years to come. Calibrating your test and measurement hardware regularly is critical to ensuring quality measurements and traceability. With multiple levels of calibration available worldwide, in addition to flexible options for service, NI can help you maintain peak performance while meeting your budgetary and uptime needs.
Calibration is the process of calculating a conversion factor so that the parameters measured by the recording device can be converted into eye movements. Therefore, a faulty calibration will cause the amplitude of the eye movements to be inaccurate in all of the subsequent subtests in the ENG or VNG test battery. Let us examine the calibration procedure in more detail and identify the causes that can lead to calibration errors.
