What are Voltage & Current data loggers?

Voltage & Current data loggers are devices that measure and record electrical signals over time. Lascar’s EasyLog range makes it simple to capture accurate voltage and current readings for testing, diagnostics and energy management.

What’s the difference between the EL-USB-3 and EL-USB-4 Voltage & Current loggers?

The EL-USB-3 records 0–30V d.c. voltage, while the EL-USB-4 is designed for 4–20mA current loop monitoring. Both store over 32,000 readings and include programmable alarms for when levels move out of range.

How do you use the Voltage & Current data loggers?

Connect the logger to your PC via USB, configure settings in the free EasyLog software, and then deploy it to start recording. Data can be downloaded later for graphing, analysis and reporting.

How long can Voltage & Current loggers record for?

Each device stores over 32,000 readings. Depending on the chosen interval (from 1 second to 12 hours), this can give you anything from hours of high-speed logging to weeks of continuous monitoring.
