True- clamp meter:This multimeter can accurately measure AC/DC Current, AC/, Frequency or Duty , Resistance, Capacitance and also provides Diode, Continuity and Temperature tests. True for accurate measurements on non-linear loads. Easy to use for labs factories and household. LowZ & :Low input impedance helps prevent readings due to ghost voltage. Low Pass Filter () for accurate measurement of variable frequency drive signals when measuring motors and transformer. To measure the current you need to clamp the meter around one of the wires and not the whole power cord. NCV Detection Function:Non-contact voltage detection effectively check electrical status through measuring field intensity without touching any wires; The NCV button lies on the right side. Simply place your thumb on it and push. Multi-function:Two-color backlit LCD Display - When the voltage 80V, the current 3A, the LCD backlit screen turns red to warn you of high voltage / LED Flashlight / Temperature Measurement for liquids and air conditioning ports included K-Type Thermocouple / Low Battery Indication / Auto power off after 15 minutes inactivity. Safety Service:Safety standard IEC 61010-1, III 600V. Double insulation. Power Suplly:3*1.5V AAA batteries(Not included batteries) Colour:Red Material:ABS Package Contents: 1 x Digital Clamp Meter(3*1.5V AAA batteries not included) 1 x test lead 1 x thermocouple wire 1 x carrying case 1 x English Manual Only the above package content, other products are not included. Note: Light reflection 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.
