Parameters:
1. Measurement accuracy: 1+/-2 percent of the word
2. Display: 0.32-inch LED digital tube, voltage with 4-bit red LED display, current with 4-bit green LED display, timing, frequency with 5-bit red LED display
3. Measuring range:
- Voltage: AC80-300V
- Current: AC0-100.0A
- Frequency: 45-65Hz
- Cumulative timing: 1m-99999h
4. Measuring speed: about 2 times/s
5. Installation: din-rail type directly mounted on the same rail as the air switch
6. Dimensions: 54 x 80 x 64mm
Usage and wiring method:
1. Connect the measured voltage to terminals 1 and 2 at the lower left 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 any choice, you 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 measurement
3. After connecting the wires according to the wiring diagram, put on the measuring voltage, the meter will start to display normally, the meter will display the measured voltage, current and frequency, press the button (SAM CK) on the left side of the meter panel, the frequency display on the meter will be converted to the cumulative timing display, and press the button (SAMCK) again, the cumulative timing display will be converted to the frequency display
4. Accumulated timing back to zero operation: press the left button (SAM CK) on the instrument panel, so that the frequency display is converted to display the cumulative timing condition, and then press and hold the button (SAM CK) for 5 seconds, the cumulative timing will automatically be 1 all displayed to zero
Note: this meter is only suitable for pure AC 45-65Hz mains power supply, it can not be used for square wave, inverter output, corrected sine wave and other circuits on the measurement, otherwise the meter will be damaged
