Small green circuit board with four voltage output pins, Micro USB port, and four indicator LEDs

AD584K 4-Channel Voltage Reference Module 10.0V 7.50V 5.00V 2.50V Micro USB

SKU CH-3RSJ-4SKKS

A four-channel programmable voltage reference delivering 10.0 V, 7.50 V, 5.00 V and 2.50 V via Micro USB with 2 mm test sockets for calibrating 8½-digit multimeters

  • Four selectable reference voltages (10.0 V, 7.50 V, 5.00 V, 2.50 V) cover common calibration points
  • Built-in charge management with load switching ensures stable output during extended use
  • Micro USB power and 2 mm copper sockets allow direct connection to multimeters
  • Status LEDs confirm all four channels are active after a two-second hold
  • Designed for HP 3458A 8½-digit multimeter calibration at 6½-digit resolution

AD584K 4-Channel Voltage Reference Module

The AD584K module provides four programmable reference voltages for bench calibration and verification work. It is aimed at technicians and engineers who need stable DC sources for checking multimeter accuracy or calibrating high-resolution instruments. The board integrates charging management and load control to maintain consistent output during use. Its compact design suits laboratory benches and portable test kits alike.

Micro USB power and 2 mm copper test sockets

A Micro USB port supplies power and handles charging duties, removing the need for an external supply when a USB source is available. Four indicator LEDs confirm channel status after a two-second press of the control button. The 2 mm copper sockets accept standard multimeter probes directly, speeding up connection and reducing contact resistance during calibration routines. This combination simplifies setup for repetitive verification tasks.

Four fixed outputs: 10.0 V, 7.50 V, 5.00 V, 2.50 V

The module delivers exactly four selectable voltages: 10.0 V, 7.50 V, 5.00 V and 2.50 V, covering common calibration points for precision meters such as the 3458A 8½-digit multimeter. Calibration values are specified to 6½-digit resolution after sufficient warm-up. No other voltage levels or programmable ranges are provided, so users requiring different set points must look elsewhere.

Questions about this item

Will the AD584K module need recalibration or battery replacement after long-term use?

The module includes built-in charging management for its internal power cell, so the battery can be recharged via Micro USB rather than replaced; periodic recalibration against a traceable standard is recommended for the 10.0 V, 7.50 V, 5.00 V and 2.50 V outputs.

What limits sustained accuracy when the AD584K runs continuously?

The supplier specifies a calibration value of six and a half digits and advises sufficient preheating before use, indicating thermal drift and reference stability are the first limits encountered during extended operation.

How much heat or noise does the AD584K produce during all-day operation?

The board has no fan and relies on passive dissipation; the only audible cue is the indicator LEDs lighting after a two-second button press, and power draw is limited to the Micro USB charging and discharging circuit.
