Информация

The DM 502A Digital multimeter measures dc and ac voltage and current, dBm, dBV, resistance, and temperature. The ac functions are true rms responding. The ranges for dc voltage, ac voltage, dBm, dBV, and resistance are automatically or manually selected as desired. The current and temperature ranges are manually selected. Rear Interface connector input is pushbutton selected from the front panel. Readout in dBm or dBV is chosen by an internal jumper. The unit is shipped with the internal jumper in the dBm position. The readout is a 3 1/2 digit display using seven segment LED. The decimal point is automatically positioned depending on the operating range of the instrument. Polarity indication is automatic.
