ZC-90 Series Highly-Insulated Resistance Measuring Meter

1. Performance features and usage introduction

ZC-90 series highly-insulated resistance measuring meter (formerly known as ZC-90 series insulation resistance tester) is a portable high resistance measuring meter with digital display produced by Shanghai Taiou Electronics Co., Ltd. The meter fully complies with the requirements for measuring meter in the national standard BG/T3048.5 Test Methods for Electrical Properties of Wires and Cables  Insulation Resistance Test, making it the ideal device for testing the insulation resistance of wires and cables and other electrical products. Over the years, thousands of meters have been used in wire and cable works and anti-static product manufacturing plants, standard metering departments, electric power departments and military and scientific research units at home and abroad. In addition, the meter has been selected by the National Wire and Cable Testing Center and National Anti-static Testing Center as the equipment dedicated for product type tests.

 (1) It adopts 3 1/2-digit digital displays and bridge-type measurement circuit, characterized by high measurement accuracy and easy and accurate reading.

 (2) It adopts a portable structure, characterized by small size, light weight and easy use.

 (3) Powered by battery, the meter can work in the state of suspension over the ground, and completely solve the problem of high-voltage short circuit caused by the grounding of the water tank during the wire and cable test, which not only improves the anti-jamming capability but eliminates the attachment of power cord. In addition, it is suitable for measuring the cable in coils on the production site, and can also be powered by external voltage-stabilized source on fixed occasions.

 (4) It has a built-in timer to lock automatic readings, which is especially convenient to use when testing the insulation resistance of wires and cables and other pieces to be tested as required.
