Online Auction Description

This is from the surplus of NASA Lewis Research center.

Tektronix model DM-502 Digital Multimeter Module used in the TM-500 series of test modules.

Specifications

Readout : 3-1/2 digits

DC Volts Full Scale : 0.2V - 1KV

AC Volts Full Scale : 0.2V - 500V

AC/DC Current Full Scale : 200μA - 2A

Resistance Full Scale : 200Ω - 20MΩ

Temperature Probe - Optional

dB : -60 dB to +56 dB (NOTE: Average responding, dB calibrated)

BCD Output - Non-Floating

Input Impedance : 10 MΩ normal; FET Input on 0.2 and 2 volt scales by internal jumper

The DM 502 Digital Multimeter measures dc and ac voltage and current, dBm, dBV, resistance and temperature. The ac functions are average responding and RMS calibrated for sine waves. A single front panel control selects all ranges. A front-panel pushbutton selects dB readout of ac functions in lieu of voltage or current. Rear interface-connector input is also pushbutton selected from the front panel. Values of dB are obtained by adding the selected dB range value to the display reading. Readout in dBm or dBV is chosen by an internal jumper. The unit is shipped with the jumper in the dBm position.

An internal jumper also permits selection of fet input (>1000 MΩ) or 10 MΩ input impedance on the two lowest dc-voltage ranges. The unit is shipped with the jumper in the 10 mΩ position.

Temperature measurements are made using a Tektronix P6430 probe or other suitable sensing devices Option 2 instruments delete the temperature measuring capability.

The readout is a 3-1/2 digit display using seven-segment LED's. The decimal point is automatically positioned by the range-function switch. Polarity indication is automatic. A usable 50% overrange exists in all measurement modes except ac voltage and current, 1000V dc, and the 1 A dc current range. In overrange, the display blinks and the most significant digit is suppressed. Upon exceeding the available 50% overrange, a 1 appears in the most significant digit position. Display readings are invalid beyond this point.


I’ve seen other units of this type selling for over $150.00 but I need to liquidate my shop and test equiptment,This is in good condition.

tested and working.
