Function: Auto-ranging clamp meter with multiple functions in oneAuto Voltage Low Impedance ,Inrush -Frequency conversion measure,AC DC current ,AC/DC voltage,temperature ,capacitance -diode,on and off beep -resistance,Fire wire identification,NCV,clean data,data hold,maximum value,minimum value flashlight,Backlight,Auto ranging,auto power-off ,Low battery alert,Frequency measure[Multipurpose display]Widely used in electric power/communication / railway/construction/oil field/metering/scientific research and teaching/industrial and mining enterprises,etc.[DC current measurement]When Less than 0.4A, the signal input on the screen will flicker 0.5A will not flicker.[NCV non-contact measurement]When the NCV induction probe of the instrument is close to the circuit under test, different alarm prompts will be issued according to the voltage intensity. [Live Firewire Recognition]Insert the red test lead into the neutral frie wire port,if it is detected as a live wire,the buzzer will sound an alarm,if it is the neutral wire and the ground wire,there is no response.1000A AC DC clamp meterThe AC current range can be extended to 3000A with iFlex flexible clampAutomatic Voltage Low Impedance MeasurementInrush measureAuto rangeTrue 42mm jawColor: blue+blackMaterial: ABS[AC voltage measurement]In the AC voltage gear, short press the VFD key to enter the variable frequency measurement function.Contact temperature measurement:Rotate the switch to the temperature gear, plug in the temperature probe to measure, press the SEL button to switch between Celsius and Fahrenheit.[Inrush current measurement]Measure the maximum current at the moment when the machine is started, Set the gear to AC and DC current gear, short press to enter INRUSH measurement.[HD Backlight]Work measurement day or night.[DC current clear to zero]The ZERO clearing function is only used for DC current,and the DC current Affected by magnetic field,long press the ZERO button to reset before measurement.[42mm large jaw]Large jaw design, suitable for cable measurement within 42mm.[Data retention]Hold symbol on the screen every 3 seconds after pressing the data hold key It will flash once,press again to cancel.Package Contents:1 x Clamp Meter1 x English manualOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
