SINOTIMER SDM006 Din Rail AC Voltage Current Frequency Power Electricity Multi-Function Detection Meter 1. Measurement accuracy: 1 percent +-1 word 2. Measuring range: - Voltage: AC80-300V - Current: AC0.00-100.0A - Frequency: 45-65Hz - Power: 0-30000W - Electricity power: 0.000-99999kwh - Power factor: 1.000-0.000 3. Display the measured AC voltage, current, frequency, power, electrical energy, etc 4. Adopt flame retardant PC material and precision chip, safe to use 5. If the current is less than 100A, just pass the wire through the hole on the right side of the instrument to get the AC current 6. When the meter shows energy, press and hold the SAM CK button for five seconds, the meter will be reset 7. Automatically records the amount of power and accumulated power at the time of power failure: the instrument will continue to collect data when reconnected to the measurement power source 8. Size: 54 x 80 x 64mm
