Electrical measurement and test device for acquiring test data according to a protocol - has at least one measurement input set up for different ranges depending on control data input device

摘要

The electrical measurement and testing device (30) has at least one measurement input which can be set up for different measurement and test ranges depending on an input device. A data transfer arrangement acquires data from the measurement and test device and transfers it while providing voltage isolation. The data transfer arrangement (40) contains a processor (50), a data memory (51), a program memory (51b) and a control data transmitter (48) which works in conjunction with the control data receiver (38) of the device for voltage isolated control data transfer. The control data causes the display (33) to show which data are to be detected by the device and transferred into the data memory (51). USE/ADVANTAGE - For testing safety systems in electrical installations or modified or installed equipment. Can be simply operated without errors under adverse operating conditions.
