Overview
The TΩ Meter 5478 is a digital multipurpose tester intended for testing, analyzing, inspecting and periodic maintaining of high voltage insulations. The main reasons why insulations fail are due to excessive heat, moisture, dirt, vibrations and aging. To detect such deteriorations in order to initiate preventive maintenance procedures it is necessary to perform regular resistance tests.

The TΩ Meter 5478 offers a complete set of functions to measure and detect effectively all parts of current in an insulation system. The instrument can supply an output power of 5 watts and a test voltage of up to 5000 volts, and therefore measure insulation resistances up to 5TΩ.

The instrument is fully automatic and requires no measuring range adjustment. A large dot matrix LCD displays measuring values and test progress at a glance. Built-in memory allows the storage of up to 1000 measuring results. Test reports can be sent over a RS-232 interface to an external computer.
