The V460 is ideal for precision temperature measurement, using mixed resistive and diode sensor types. The programmable current sources and low duty-cycle scanning assure low sensor self-heating. Programmable digital filtering allows selectable rejection of AC line hum and other noise sources.

The V460 can measure resistances from 5.12 Megohms full scale (with 78-ohm resolution) to 80 ohms full scale (with 1.22 milliohm resolution); voltages from 5.12 volts full scale to 80 mV full scale may be measured, with resolution to 1.22 microvolts. Extensive internal self-tests help assure accurate measurements.
