Designed for use in the TEK TM5000 Series Mainframes, the Tektronix DM 5010 Programmable Digital Multimeter measures dc voltage, resistance, true RMS ac voltage and true RMS ac+dc voltage. The internal math capability of the DM 5010 provides most of the calculations normally required for reducing raw measurements to decision-supporting information without controller assistance. These caculations include averaging (up to 19,999 measurements), offset and scaling, conversion to dBm or reference dB and Hi/Lo/Pass comparisons. User-selectable constants required for calculations may be supplied either through the front-panel keypad or via the GPIB.
The internal math capability of the DM5010 permits such specialized measurements as: ac or dc current measurements, through the use of an external shunt resistor and a scaling factor equal to the ohmic value of the resistor; comparison against a percent tolerance (as opposed to an absolute value tolerance) through the combined use of the scaling and Hi/Lo/Pass functions.
The low voltage function (0.2 volt) ohms function allows in-circuit resistance measurements without turning on parallel diode and transistor junctions. A Diode Test function is provided for forward and reverse testing of diode and transistor junctions.
====================================
The DM5010 Programmable Digital Multimeter measures DC Volts, Resistance, True RMS (AC or AC+DC) Voltage, and even AC/DC Current (w/ext. shunt resistor and a scaling factor). 4 1/2-digit readout, autoranging, diode test, & math functions such as dB calculations, averaging, offset, scaling, and Hi/Lo/Pass. It is used in the TM5000 frames.
