Parameters:1. Measurement accuracy: 1+/-2 percent of the word2. Display: 0.32-inch LED digital tube, voltage with 4-bit red LED display, current with 4-bit green LED display, timin g, frequency with 5-bit red LED display3. Measuring range:- Voltage: AC80-300V- Current: AC0-100.0A- Frequency: 45-65Hz- Cumulative timing: 1m-99999h4. Measuring speed: about 2 times/s5. Installation: din-rail type directly mounted on the same rail as the air switch6. Dimensions: 54 x 80 x 64mmUsage and wiring method:1. Connect the measured voltage to terminals 1 and 2 at the lower left of the meter2. 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 measurement3. 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 display4. 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 zeroNote: 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 damagedSpecification: Package Weight One Package Weight 0.14kgs / 0.32lb One Package Size 9cm * 6cm * 7cm / 3.54inch * 2.36inch * 2.76inch Qty per Carton 140 Carton Weight 20.70kgs / 45.64lb Carton Size 51cm * 38cm * 32cm / 20.08inch * 14.96inch * 12.6inch Loading Container 20GP: 429 cartons * 140 pcs = 60060 pcs40HQ: 998 cartons * 140 pcs = 139720 pcs Show more
