Designed for use by non-technical personnel, such as crews, servicemen, meter readers, etc., but also suitable for the most experiences engineers and technicians.

10 megohms input resistance practically eliminates low potential readings caused by resistance in the external circuit due to contact resistance of the reference electrode. This condition is frequently encountered in city work and in frozen ground.
