The testo 760 digital multimeter family comprises three models for all important electrical measuring tasks. Function keys replace the traditional dial on all three instruments, which means easier operation and greater reliability. Incorrect settings are now impossible, because the measurement parameters are detected automatically via the assignment of the measuring sockets and also shown by the illumination of the appropriate function keys. This prevents accidentally blowing the meter�s fuse because of incorrect connections.The testo 760-1 model is the standard version for virtually all daily measuring tasks.
