USB is a popular option for data acquisition for many reasons. 1. With a USB hub you can connect many devices to one socket - letting you easily expand your system should requirements grow. 2. The equipment can obtain power from the USB; it doesn't need to be battery powered or plugged into the wall. This makes USB ideal for portable data acquisition with a laptop. 3. You can plug in and unplug your equipment without switching off your computer or restarting Windows. 4. The USB cable can be up to 5 m long. However, using USB hubs between cables you can reach 30 m. 5. You can use USB devices alongside existing data acquisition equipment. USB data acquisition units are available from the Windmill on-line shop at https://www.windmillsoft.com/daqshop/data-acquisition.html. These let you: - measure temperature, strain, pressure, resistance, voltage and current - control analogue voltage and current outputs - switch digital outputs - monitor digital inputs - count events Prices start at just £295 for hardware, drivers and Windmill Logging, Charting and Control software.

What is the quickest way to find the problem? Let's use as an example a formula to find the average readings per hour: =SUMIF(Hour,"=16",Temperature)/COUNTIF(Hour,"=16") (See Monitor 80 for details: http://www.windmill.co.uk/monitor80.html#Excel) Highlight the SUMIF part and press the F9 key. Excel shows you the results for just this part of the formula. Now do the same with the COUNTIF part. A quick and easy way to see which is causing the problem.
