RESISTOMAT® model 2408 megohmmeter has been especially developed to measure extremely high resistance values with a high degree of accuracy. This instrument has a specifi cation that makes it suitable for all common applications. The measurement voltages equal those given in the DIN test regulations (e.g. DIN 51953, DIN 53482, DIN 54345, DIN 57281 and DIN 57411) for measuring the electrical resistance value across fi lms, fl oor coverings, test equipment, cables, moldable materials, rubber, plastics, insulating oils and the like.
Fast serial measurements can be performed using the integral limit indicator. If the reading lies below an adjustable limit, the pass/fail limit indicator trips and enables a potential-free output. All functions can be PC-controlled via the built-in RS232 interface provided as standard.
The guard circuit in shield technology can be used to measure individual resistances in a delta connection. This means, for instance, it is possible to measure the insulation resistance between wire and shield on a 2-core cable with common shield without the result being distorted by the two guard resistances lying in parallel (see diagram overleaf).
