THM500 Series Instruments The Tektronix THM500 Series instruments combine the features of a complete digital multimeter (DMM) with the power of an oscilloscope, all in a single package. The DMM portion of these instruments measure true RMS AC and DC voltage, resistance, continuity with audible mode, and a diode test.
Page 5 THM500 Series Instruments THM500 series instruments will also store waveforms, settings, and displays. With these features, you can do the following: Recall settings Automate test procedures Save waveforms and screens in the field for later analysis Transfer waveforms and screens to a personal computer...

Page 12: Thm500 Series Performance Verification
THM500 Series Performance Verification This section contains procedures to verify that the THM500 Series instruments perform as warranted. Verify instrument performance whenever the accuracy or function of your instrument is in question. The performance verification procedures provide a valid confirmation of...
Page 13: Test Equipment
THM500 Series Performance Verification Test Equipment The performance verification procedures use external traceable test equipment to directly check warranted characteristics. Alternative test equipment must meet or exceed the intended minimum requirements specified in Table 6. If you substitute equipment, you may need to modify the procedures.
