Programmable 4 Channel Voltage Calibration Module Srliya USB

Description

Product Overview

The Srliya Programmable 4‑Channel Voltage Calibration Module is engineered to meet the exacting standards of modern laboratory and industrial calibration environments. Built around a high‑precision reference voltage source, the module offers four selectable output levels—10.0 V, 7.5 V, 5.0 V, and 2.5 V—each calibrated to six‑and‑a‑half‑digit accuracy, ensuring that even the most demanding multimeters such as the HP3458A receive reliable reference signals. The unit measures 5.12 × 3.15 × 1.18 in and weighs only 1.13 oz, making it easy to mount on a test bench or integrate into portable calibration kits. A robust micro‑USB interface provides both charging and discharging capabilities, while a 2 mm copper test socket simplifies connection to a wide range of instruments. The module incorporates loading and unloading protection circuitry that safeguards both the reference source and the device under test, extending the lifespan of the equipment. Indicator LEDs for each channel illuminate simultaneously when the module is powered, offering immediate visual confirmation of operational status. All components are selected for thermal stability and low drift, guaranteeing consistent performance over extended periods of use.

Usage

Designed for professional calibration technicians, research laboratories, and quality‑control facilities, this module fits seamlessly into a variety of workflows. When calibrating an HP3458A multimeter, the user simply connects the appropriate test socket, selects the desired voltage level via the front panel, and allows the device to stabilize; the module’s indicator lights confirm that the correct channel is active. The micro‑USB charging port enables rapid battery replenishment without removing the unit from the test environment, reducing downtime. Because the module supports a broad temperature range and includes built‑in protection against overload, it can be employed in field service scenarios where environmental conditions may fluctuate. Additionally, the precise reference voltages are suitable for calibrating other instrumentation such as data acquisition systems, voltage standards, and custom test rigs. The compact form factor allows the module to be stored in a standard equipment drawer or carried in a protective case for on‑site calibration tasks. Users benefit from the intuitive layout, which minimizes the learning curve and accelerates routine calibration procedures, ultimately improving throughput and measurement confidence.

FAQ

How do I select the desired output voltage?

Press and hold the power button for two seconds to activate the module; all four indicator LEDs will illuminate. Then use the channel selector switch to choose the required voltage level—10 V, 7.5 V, 5 V, or 2.5 V. The selected channel’s LED will remain solid, confirming the output setting.

Can the module be used with instruments other than the HP3458A?

Yes. The module’s precise reference voltages are compatible with a wide range of calibrated equipment, including other high‑precision multimeters, data acquisition units, and custom test rigs that require stable voltage references.

What is the expected battery life when using the micro‑USB charging feature?

Under typical calibration workloads, the internal battery provides up to 12 hours of continuous operation before requiring a recharge. Charging via the micro‑USB port restores full capacity in approximately two hours.

Is the module protected against accidental short circuits?

Absolutely. Built‑in protection circuitry detects overload conditions and automatically shuts down the affected channel, preventing damage to both the module and the connected instrument.

What warranty and support does Srliya offer?

Srliya provides a one‑year limited warranty covering manufacturing defects, along with access to technical support, firmware updates, and calibration documentation to ensure optimal performance throughout the product’s lifecycle.
