Page 5: General Function And Description
The alphanumeric LCD-display is the information center of the Charge Analyzer 711 and allows the user to observe the principles of static protection. The unit’s high accuracy makes it well... - Page 6 This feature allows to the user to make measurements by means of a hand-held or fixed position probe in remote locations, where it may be impossible to position the Charge Analyzer 711. Measurement distances with the probe are 1, 2, 5, 10 and 20 centimeters. The built-in microprocessor automatically converts the measured field strength via the chosen distance into a charge of an equivalent potential in volts.
