Voltage measurement range from 7 to 120 VDC and 0 to 120 VDC provides coverage for a variety of low voltage tasks. Touch control enables convenient, fast operation without complex setup. Low voltage alarm function alerts you when the voltage drops too low, helping protect circuits and equipment. Reverse polarity protection safeguards the device and the connected circuit from incorrect connections. Digital display presents the voltage reading clearly and at a glance. Key benefits - Simple and reliable voltage checking for low voltage systems - Quick operation with touch control, reducing setup time - Built-in alarm helps prevent damage from undervoltage conditions - Protects both the device and connected circuitry with reverse polarity protection - Clear, digital voltage readout for accurate monitoring Practical use scenarios - Automotive and vehicle electrical work: verify battery health and charging state by monitoring DC voltage within the 0–120 V range, with the alarm signaling when voltage is too low. - DIY electronics and prototyping: measure DC power supplies and circuits up to 120 V during development and testing, using convenient touch control for fast checks. - Solar power and backup systems: monitor panel output and battery voltage to maintain safe operation and prevent undervoltage conditions.
