Quick, accurate ground and voltage testing built for professional use Key benefits Save inspection time: measures ground resistance in 5 seconds and voltage in 2 seconds, speeding up routine checks and troubleshooting. Protect personnel and equipment: double overload protection rated to 300 V AC lets you perform extended tests with reduced risk of damage. Adaptable to different jobs: three selectable measurement ranges handle a variety of test conditions without changing instruments. Reduce reading errors: a large HD display presents measurements clearly for fast, confident decision making. What it does (core functions) Ground resistance measurement: fast, reliable readings in 5 seconds to verify grounding systems. Voltage measurement: accurate readings in 2 seconds for AC circuits up to 300 V. Three adjustable measurement ranges to match different testing requirements and improve accuracy. Why professionals choose it Designed for professional field and site use, it simplifies routine inspections, commissioning, and maintenance by combining speed, safety, and clear readout. The overload protection and the quick measurement cycles reduce downtime and lower the chance of repeated tests. Practical applications Electrical safety inspections: verify grounding performance and line voltage during periodic building safety checks. Field service and troubleshooting: quickly isolate grounding faults and confirm voltage levels while minimizing service time on site. Commissioning and maintenance: validate installed grounding systems and power connections during equipment startup and routine maintenance. Compatibility and performance notes Intended for professional electrical testing environments and standard AC systems up to 300 V. Three measurement ranges let you tailor the instrument to typical field conditions and required resolution. Large HD display improves legibility in dimly lit areas and reduces reading mistakes during important tests. Ideal users Electricians, facility managers, maintenance technicians, and commissioning engineers who need fast, safe, and dependable ground and voltage measurements.
