Description
Agilent/HP Model 3490A Multimeter is a five-digit integrating digital voltmeter. The basic model measures DC voltages, AC voltages and resistances.
Several options that are available with this model can achieve additional measurement capability.
HP 3490A uses a dual slope integrating technique and is fully guarded, providing excellent noise immunity at five readings per second on all DC ranges.
Ranging is automatic on all functions over all ranges. DC measurements can be made with 1 microV resolution on the 100 mV range.
AC voltage measurements can be made from 20 Hz to 250 KHz in four ranges. The 1 V range provides 10 microV of AC voltage resolution.
Ohms can be measured by the four-wire conversion technique which eliminates errors due to test load resistances.
Six ranges of ohms are provided(100 ohms range included). All functions and ranges include 20% overranging except the 1000 V range.
Light Emitting Diodes(LED’s) are used in HP 3490A. These LED’s are seven segment type. The extremely high reliability of this LED display assures maximum life.
At the flip of a switch, HP 3490A Digital multimeter sequences itself through 10 tests that check timing signals and autoranging circuits, validate the performance of most logic-circuit IC’s and check the six-digit LED display.
These tests, and six others provided by six additional front-panel switches, cut calibration costs and ensure the DMM is ready to make accurate measurements.
The standard 3490A includes five ranges of DC measurement capability from 100 mV to 1000 V.
Measurements are made from the front panel at a precise five readings and at a slower rates, using digitally controlled sample rate selector.
High input resistance assures accurate measurement of high impedance sources.
Four ranges of AC measurements are provided. The average AC value is accurately detected, and the rms value is displayed with five digits of resolution.
Full autoranging, wide frequency response, and 20% overranging are designed-in features to permit easy operation.
Six ohms ranges are standard and all ranges provide true four wire ohms measurement capability.
Maximum current through the unknown is approximately 1 mA.
Over voltage protection for ohms sensing terminals insures maximum protection against inadvertent application of a high voltage to ohms terminals.
Over-voltage protection is provided to 250V and fuse protection to 1000V.
