Operating manual for DESCO EMIT 50551/50552 static field testers, covering setup, zeroing, measurements and accessories.
This manual provides step‑by‑step instructions for using the DESCO EMIT 50551 and 50552 static field testers. It explains how to power on the device, perform zero calibration, and measure surface static voltage at a standard 1‑inch distance.
The guide also details the optional electrode plates (50554, 50553) for ion‑balance and discharge‑time testing, lists the contents of each kit, and outlines the one‑year warranty terms. This manual is written in Chinese.
