Gems Sensors & Controls, of Plainville, Connecticut, designs and manufactures a broad portfolio of liquid level, flow, and pressure sensors, miniature solenoid valves, and pre- assembled fluidic systems to exact customer requirements. The large number of configurable products, and the company’s high production volumes, create complex testing requirements. For example, many AC and DC voltages and resistance measurements need to be performed on the large number of different liquid level sensors that are built on a flexible production line.

Jeff Neuner, senior test engineer for Gems, overcame this challenge by developing an innovative testing application that scans a barcode to identify the part number and product configuration information. The test application software uses this product information to create a custom test profile. The application takes advantage of the versatility and speed of the 8845A precision multimeter from Fluke Corp., located in Everett, Washington, to handle many different part numbers and easily keep up with the production pace. The new multimeter has replaced three instruments that were required in the past, which saves floor space, simplifies test system architecture, and reduces maintenance expenses.
