The voltage and current signal generator is available in two variants: Type 1 (battery not included) and Type 2 (battery included). It provides essential components for efficient testing of voltage and current signals. Key features and benefits - User friendly display: 4-digit high-definition digital tube with brightness adjustable from 1 to 8, ensuring clear visibility in different lighting conditions. - Flexible power options: supports external DC5V, built-in lithium battery, and compatibility with DC 15-30V sources to suit bench, field, and industrial environments. - Easy parameter saving: save voltage and current values with a single encoder click, eliminating the need to re-enter settings after restart. Use scenarios - Benchtop testing: wire to an external DC5V or DC 15-30V supply to generate repeatable test signals for electronic circuits. - On-site or field service: use Type 2 with the built-in battery to test devices without external power. - Production or R&D: quickly recall and reuse saved voltage/current settings to speed up repetitive tests and calibrations.
