Features Dual Display Meter: The digital AC voltage and ammeter dual display meter can display the measured AC voltage and AC current separately at the same time. LCD display: The LCD display is blue backlight and the measurement and reading are very convenient. Voltage and current can be clearly displayed at the same time. Small Current Transformer: The instrument is equipped with a precision small current transformer, no need to add additional working power and AC transformer. No need to buy another one. It can be flexibly installed in any position. Wide measurement range: The dual voltage current meter measurement range is AC80-300V, current measurement range is AC0-50A, AC0-100A. Once the instrument is inserted, the required parameters can be tested. High Measurement Accuracy: The dual voltage current meter accuracy up to 1% ± 2-digit. You can use it with confidence. Small error of measurement results, safe and reliable.
