Irfora Digital Multimeter Ground Resistance Solar Power Generation Voltage Meter Tester, Tester,

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- It has the features of high precision, strong anti-interference and high reliability, and is widely used in fields such as electric power, communications and railways. Multiple gears can be selected, and voltage and resistance can be measured by shifting the gears (only for the DY4100B with soil resistivity measurement function). Photovoltaic voltage test range: -1500V to 1500V. Accurately and quickly obtain the open circuit voltage of photovoltaic modules. When testing earth resistance and soil resistivity, the series interference voltage will be automatically synchronously tested. If the test result is abnormal, a prompt will be displayed. The large, clear digital display screen is easy to read and convenient. Features: High accuracy, strong interference resistance, and high reliability make this instrument widely used in fields such as power generation, communications, and railways. It features multiple gear selection and allows for gear shifting to measure voltage and resistance. (Only the DY4100B has soil resistivity measurement functionality.) Photovoltaic voltage test range: -1500V to 1500V. Accurately and quickly obtain the open-circuit voltage of photovoltaic modules. Automatically and synchronously test series interference voltage when testing ground resistance and soil resistivity. A prompt will appear if the test results are abnormal. The large, clear digital display is easy to read. The backlight function ensures clear viewing even in dark places. Made with high-quality materials and excellent craftsmanship, it is wear-resistant and will last for a long time.
