The | The DM502'''A''' model adds an input for a PT-100 temperature probe ([[P6601]]), a true RMS converter, and offset circuits to read dB directly in all ranges. An "Option 2" instrument deletes the temperature measurement function, P6601 temperature probe, and all internal circuits associated with this function. The rear interface of DM502'''A''' is limited compared to the DM502: No current input and no reading output, see gallery below. | ||
