Single-phase domestic guide rail digital display voltage current frequency power factor power multifunction measuring instrument

General Description The domestic single-phase rail is a multi-function measuring instrument designed to monitor various electrical parameters such as voltage, current, frequency, power factor, and power. It is equipped with a clear and precise digital display, making it easy to read the measured data. Technical Specifications Accuracy: 1% ± 2 words Measuring Range: AC Voltage: 40.0-300.0 V AC or 250.0-450.0 V AC (selectable multimeter type) AC Current: 0-100.0 A AC, resolution: 0.01 A Frequency: 45.0 Hz – 65.0 Hz Power Factor: 0.00-1.00 PFP Power: 0-450,000 W, resolution of 0.1 W for 0-9,999.9 W; Otherwise, resolution of 1 W. Electrical energy: 0 to 99,999 kWh, display resolution of 0.01 kWh for 0-999.99 kWh, 0.1 kWh for 1,000-9,999.9 kWh, and 1 kWh for > 9,999.9 kWh. Display speed: 2 speeds per second. Dimensions: 54 × 80 × 64 mm. Installation: DIN rail. Installation: Connect the measurement voltage to terminals 1 and 2. Connect the multimeter with an internal current transformer. Pass the wire through the multimeter opening and select the direction of rotation. For an external current transformer, insert the wire into the meter's opening and connect the secondary transformer wires to terminals 3 and 4. Upon power-up, the meter displays the measurement parameters. Operation: Upon power-up, press the SAM CK button for 5 seconds. To reset the electrical energy to zero. Data accumulation will begin as soon as the button is released. Upon power-off, the meter will record the electrical energy value and will continue accumulating data upon the next power-up. Other information: This meter can only be used to measure mains AC current from 45 to 65 Hz.
