It is a 2in1 Digital Voltmeter Ammeter/Digital Tester, Voltage Measuring Range: AC 80.0 ~ 300V, Current Measuring Range: AC 0 ~ 100.0A,  Applications:The meter can be used in  audio amplifier, power distribution box, distribution cabinet, regulators, teaching aids, household small distribution box, etc.

• Voltage Measuring Range: AC 80.0 ~ 300V
• Current Measuring Range: AC 0 ~ 100.0A
• Measuring accuracy: 1% ± 2digits
• Voltage display: Yellow LED
• Current display: Blue LED
• Size: 70*39*40 mm

• Green terminal: connect voltage input
• Blue terminal: connect current transformer secondary input
• Note: Please let the wire of the measuring circuit pass through the hole of transformer.

• 1. Voltage input (green terminal) and current transformer secondary input (blue terminal) cannot be connected to the wrong terminals, otherwise the instrument will be burned out.
• 2. Only use for pure AC 50Hz-electric power supply. The meter will get permanent damage if you measure the square wave, dc-to-ac inverter output and modified sine wave.

• 1 x Digital Voltage & Current Meter ( 2in1 Digital Meter )
• 1 x Current Transformer
