The meter will not only automatically select the measurement range, but will also independently determine whether we are currently measuring resistance, circuit continuity, direct or alternating current voltage. This makes the meter very easy to use. In standard meters, before the measurement, we must set the appropriate measurement range and measurement type ourselves. In this meter, after turning it on, you just need to place the measuring probes, e.g. on the battery poles, and then read the result.\u003cbr\u003e\u003cbr\u003eBasic measurements\u003cbr\u003e\u003cbr\u003eAC voltage measurement: A.C. 0-600V, TRUE RMS\u003cbr\u003eDC voltage measurement: D.C. 0-600V\u003cbr\u003emeasurement of alternating current: A.C. 0-10A, TRUE RMS\u003cbr\u003emeasurement of direct current intensity: D.C. 0-10A\u003cbr\u003eresistance measurement: 0-60M\u003cbr\u003ecircuit continuity test: 0-50\u003cbr\u003eAdditional measurements\u003cbr\u003e\u003cbr\u003enon-contact detection of alternating voltage: NCV\u003cbr\u003eMeasurement accuracy\u003cbr\u003e\u003cbr\u003eAn example of determining accuracy for measuring AC voltage.

The device first measures the actual value of the sine wave at several time intervals  then squares the measurement results  sums them  calculates the average  and finally squares the average result. The measurement result is the real effective value of alternating voltage\/current, even for a deformed sine wave or square wave;\u003cbr\u003eNCV - non-contact detection of alternating voltage using the inductive method. The meter detects the presence of voltage in the insulated wire using the NCV sensor on the front of the device;\u003cbr\u003eAUTO - automatic adjustment of the measurement range. When measuring unknown values using a meter with a manual range change using a knob, measurements should be performed sequentially from the largest range to the range giving the most accurate result - otherwise you risk damaging the device. However, in the case of a multimeter with the AUTO function, it is enough to perform one measurement and the meter will automatically find the optimal range;\u003cbr\u003eSMART - automatic recognition of the measurement type. The meter will recognize itself whether we are measuring direct or alternating current voltage. If no voltage is present, the meter automatically switches to circuit resistance measurement mode;\u003cbr\u003eDATA HOLD - keeping the currently measured value on the display.\u003cbr\u003eAdditional information\u003cbr\u003e\u003cbr\u003eLCD display, maximum displayed result: 5999\u003cbr\u003escreen backlight\u003cbr\u003eaudible signal in the continuity test for resistance below 50\u003cbr\u003eThe set includes measurement probes with a length of 12 cm\u003cbr\u003ecable length with probes: 84 cm\u003cbr\u003ewire diameter with insulation: 3.5 mm\u003cbr\u003eABS plastic housing\u003cbr\u003eautomatic shutdown of the meter after 15 minutes of inactivity\u003cbr\u003elow battery indicator\u003cbr\u003epower supply: two 1.5 V (AAA) batteries\u003cbr\u003e\u003cbr\u003e","brand":"Sthor","offers":[{"title":"Default Title","offer_id":56528465789310,"sku":"81772","price":9.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/5097\/7918\/files\/34ea0e33bd365f682bae8cf2ae5488cb.jpg?v=1767384502","url":"https:\/\/irankiuturgus.com\/products\/skaitmeninis-daugiafunkcinis-testeris-ismanus-true-rms-81772","provider":"irankiuturgus.com","version":"1.0","type":"link"}
