-   120,000-count resolution with 0.025% basic DC voltage accuracy (1-year specification)
-   10 DMM functions: DCV, ACV, DCI, ACI, 2- and 4-wire resistance, frequency, continuity, diode, and capacitance
-   4-wire milliohm measurement with 0.001 mΩ resolution for low-resistance characterization
-   8 built-in math functions
-   OVP and OCP load protection to safeguard the device under test
-   Ramp and scan sweep (up to 100 scan steps, 10,000 ramp steps) plus square-wave output to 4.8 kHz
-   GPIB (IEEE-488) and USB 2.0 interfaces for remote control and automated test systems
-   Kensington lock slot for physical security against theft or misplacement

The Keysight U3606B Multimeter | DC Power Supply is a one-box source-and-measure device that pairs a full-featured 5½-digit digital multimeter with a built-in 30-W DC power supply. Because a single unit can power the device under test while simultaneously measuring voltage and current, it performs two test functions in the same instrument, occupying a compact footprint in place of two separate boxes. The combined unit is lighter than a standalone DMM and power supply together, making it straightforward to move between benches.

The U3606B is suited to applications across education, commercial electronics, semiconductors, sensors, and research and development. Its ramp and scan sweep functions simplify device characterization for multilevel DC bias testing such as DC motor testing, transistor gain test, relay control, and margin tests. The square-wave output serves uses including pulse-width modulation (PWM), adjustable voltage control, and synchronous clock generation, and supports checking and calibrating flow-meter displays, tachometers, LEDs, sensors, oscilloscopes, frequency converters, frequency transmitters, and other frequency-input devices.

ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Holding equipment on-site lets our team support buyers directly and turn orders around quickly.

## Brand Heritage

Keysight Technologies traces its test-and-measurement roots to Hewlett-Packard, whose instrument business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement division was then established as Keysight Technologies in 2014, the brand under which this product is offered today.

> **Important:** Safety class I instrument: the protective earth terminal must be connected to an earth ground through a power source with a 3-wire ground receptacle.

> **Important:** Any current measurement greater than 500 mA will have a temporary thermo-effect. If you wish to measure a lower current or offset current immediately after a high-current measurement, ensure that the U3606B has cooled down.

> Recommended pairing: the 11059A Kelvin probe set or 11062A Kelvin clip set listed among the accessories supports the four-wire low-resistance (milliohm) measurement function.

> **Important:** For resistance measurements above 100 kΩ, a shielded test cable is recommended to eliminate noise interference that may be induced by the test leads.

> **Important:** For 2-wire resistance measurements without using the Null math operation, add a 0.2 Ω error.

> Recommended pairing: the U8202A Electronic Test Lead Kit and 34133A Precision Electronic Test Leads listed as accessories for the DMM function.
