Tektronix TM503 w/DM502 digital multimeter plug-in
Tektronix TM503 Main Frame with DM502 Digital Multimeter
Unit powers up and DM displays input voltage from power supply correctly as shown.
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.
Interlaced bcd output (1,3,2,4) referenced to the low input is available at the rear interface connector if user wired.
The DM 502 is not directory compatible with the 153 Calculator Interface since the output is not floating
The maximum input voltage is 1 kV, 350 V at the rear connectors. The front-panel HI and LO connectors may be floated 1 kV maximum above ground, the rear inputs 350 V.
