Tektronix DM502A

The DM502A Digital Multimeter measures seven different functions with push-button convenience. Measures DC and AC voltage, DC and AC current , dB, resistance and temperature. True RMS provides more accuracy in AC measurements on distorted, noisy, random or other non-sinusoidal AC waveforms. Resistance mode features HI-LO voltage (2 V to 0.2 V). Requires TM-Series Power Module. Temperature probe not included.
