Tektronix DM 501A Multimeter

Selling an extra DM 501A module. I upgraded and have not been using this.

DC is spot on compared to my calibrated meter. Resistance is spot on. AC is not accurate and measures low. I never used current measurement, so I'm not sure about accuracy.

Photos show 9V battery, 4.7K Ohm resistor and the AC display is 1K Hz @ .775V. As you can see, it measures low.

Asking $100 or reasonable offer plus shipping from 17403. 20201212_144337.jpg20201212_144320.jpg20201212_144051.jpg20201212_143931.jpg20201212_143837.jpg
