Firstly, turn on the stamina of digital multimeter and choose the test object such as voltage, current, resistance and other object. Secondly, determine a range, when we might be unsure the range, a number of set the range to finally maximum, then gradually lessen maximum range. Before testing, we should check the type of meter pen whether within the correct hole. When we have toggle the range switch, the force should be a little more appropriate, avoiding the harm on metal switch. After testing, rotary switch should maintain the high voltage information. Some explanations during the testing pertaining to digital multimeters For price impedance profile, the consider results of resistance is special from the test outcome of pointer table.
The slightly difference arrives to the test conditions. When testing the physical quantity that’s related to the polarity, whose polarity should be very corresponded to the multi meter pen. That is clearly when not display any polarity, the point within the red meter pen demonstrates to potential is in highend or the side which is the current into. As soon as the polarity shows””, so the thing of the red multi meter pen is in lowend potential or the team which is the current day out. Resistance profile as well diode profile are dissimilar to the pointer meter writing instrument.
When the pointer multi meter pen testing the resistance, the red pen and as a consequence black pen are other to the polarity, which usually is to say black displays positive electrode, red is an acronym negative electrode. However, ones polarity of digital multi meter is the same that includes test source. Red write stands positive electrode, jet pen stands negative electrode. صيانة سامسونج are the doing the laundry voltage and current. It won’t be confused. So appeared superior than the suggestion meter. When we are unaware of the polarity or don’t the pin order within the transistor, we can name and certain every polarity of the transistor made by times for foot while using hfe profile of transistor.
Calibration Electric powered multimeter in order to be calibrated quite often.
