Measurement errors when estimating the vertical jump height
Abstract. Common methods to estimate vertical jump height (VJH) are based on the measurements of flight time (FT) or vertical reaction force. This study aimed to assess the measurement errors when estimating the VJH with flight time using photocell devices in comparison with the gold standard jump height measured by a force plate (FP).

Consider a setup with a photocell and a cathode enclosed within a vacuum tube. Monochro-matic light is allowed to fall on the photocell, which emits electrons. These are collected by the cathode, and returned to the photocell completing the circuit. This collected electric current is measured.
Concurrent-Validity and Reliability of Photocells in Sport: A
For this reason, the purpose of this systematic review was two-fold: (i) to summarize the evidence about the concurrent validity of photocell timing for sports analysis; and (ii) to summarize the evidence about the reliability of photocell timing for sports analysis. Particular attention was also paid to the applied experimental procedures.

6 FAQs about [Photocell Error Analysis]
What are common problems with photocells?
Common Problems with Photocells and How to Fix Them Introduction 1. Faulty Wiring 2. Overly Sensitive Photocell Sensor 3. A Confused Photocell 4. Debris Accumulation 5. Aberrations in Photocell Conclusion Meta Description
What causes a photocell to stop working?
For example, a loose wiring, or wrong wiring can result in a totally nonfunctional photocell. Similarly, debris accumulation over the time may cause a photocell to stop working. However, where these might be the common reasons of malfunctioning photocells, make sure that the problem doesn’t lie with your light fixture.
What should I do if my photocell is not working?
check your photocell for any cracks and crevices or broken, chipped parts. If you think these cracks and damages are a reason for your nonfunctional photocell, you might not have any other option but to get your photocell replaced by a new one, and obviously a better one this time.
Why should you choose a photocell unit?
By ensuring secure and tight wiring, keeping the photocell units free of debris and by choosing weather resistant, high quality units, you can avoid these problems and ensure consistent light. Photocells, undoubtedly, have added to our convenience and they act as an effective tool against power wastage, making sure only as much is used as needed.
