3. Measuring speed: 2 times/s
4. Installation mode: rail type
5. Overall dimensions: 54 x 80 x 64mm
6. Protruding size: 45 x 16mm

Usage and wiring method:
1. Connect the measured voltage to terminals 1 and 2 on the lower left side of the meter
2. Built-in transformer according to figure 1 wiring diagram wiring, the measurement circuit of the wire through the instrument lower hole, the wire into the direction of the user according to the use of arbitrary choice, can be from the instrument lower hole into the upper out, or from the instrument upper holes into the lower out, into the direction of the different will not affect the results of the measurements
3. Connect the external transformer according to the wiring diagram in figure 2, connect the two wires of the secondary end of the precision current transformer with the instrument to the 3 and 4 terminals on the upper left side of the instrument, and pass the wires of the measuring circuit through the hole of the transformer
4. When the power is turned on, the meter displays the measurement parameters
5. When it is necessary to reset the power measurement (when the measurement starts from zero), press and hold the button on the right side of the meter panel (RESET) for 5 seconds (press and hold and stay for 5 seconds) until the power is displayed as 0, then release the button, then the power measurement starts from zero
6. Power outage automatic data saving function, that is, when the measurement voltage is disconnected or power failure, the meter will automatically save the current test data, when reconnected to the measurement of the power supply meter will continue to add up on the original saved data
7. Built-in transformer (CT) hole diameter 11mm can pass through the national standard 12 square (mm) standard copper wire / can meet the load current 100A through, external transformer (CT) hole diameter 15mm can meet the national standard 21-25 square (mm) standard copper wire through

Note: the instrument measuring voltage range of 250-450V range only applies to pure AC 45-65Hz mains power supply, the measuring range of 40-300V is not limited
