    Tektronix DM501A 4 1/2 Digit Multi--Meter

    Option 002 - deletes the temperature probe and measurement capability.
    ====================================================
    This digital multi-meter occupies a single slot in any standard TM500 series mainframe. It measures DC Volts (ranges 2V - 1000), AC Volts (2 - 500), AC and DC Current,and Ohms (2K to 20 Meg-Ohm).

    ==========================================================
    The DM501A Multimeter Module measures DC voltage from 200 mV to 1000 V in 5 ranges. True RMS AC voltage ranges from 200 mV to 500 V. Resistance from 200-ohms to 20 Mohms in 6 ranges. DC and True RMS AC current 200 A to 2000 mA in 5 ranges. Temperature -62C to +240C. .
    ===============================================
    o 0.05% DC Voltage Accuracy
    o Seven Functions including Temperature and dB
    o 4 Digit Display
    o true RMS Capability
    o For use in any TM500-series Mainframe
    The DM 501A Digital Multimeter measures dc and ac voltage, dc and ac current, resistance, dB, and temperature. The DM 501A gives 4 digits of readout resolution, all with 0.05% accuracy and true RMS capability. True RMS allows accurate measurement of distorted waveforms. Readout in dB is useful when making critical audio and communication measurements. Fast accurate temperature measurements to 240C come from the Tektronix P6601 (not included) platinum-film temperature sensing probe. The P6601 reaches 90% of final reading in 1.5 seconds. Power consumption is approximately 9 V A.
