Descrizione: Autoranging Digital Multimeter
Informazioni:
                                    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.
