Magnetic Loops If you are making measurements near magnetic fields take caution to avoid inducing voltages in the measurement connections You should be especially careful when working near conductors carrying large currents Use twisted pair connections to the multimeter to reduce the noise pickup loop area or dress the test leads as close together as possible Loose or vibrating test leads will also induce error voltages Tie down test leads securely when operating near magnetic fields Whenever possible use magnetic shielding materials or increased distance from magnetic sources Noise Caused by Ground Loops When measuring voltages in circuits where the multimeter and the device under test are both referenced to a common earth ground a ground loop is formed As shown below any voltage difference between the two ground reference points Vsrouna Causes a current to flow through the measurement leads This causes noise and offset voltage usually power line related which are added to the measured voltage RL Vtest Vground E P R lead resistance Ri multimeter isolation resistance Vground voltage drop on ground bus The best way to eliminate ground loops is to isolate the multimeter from earth by not grounding the input terminals If the multimeter must be earth referenced connect it and the device under test to the same common ground point Also connect the multimeter and device under test to the same elect

Self Heating Errors If you apply more than 300 Vims self heating occurs in the multimeter s internal signal conditioning components These errors are included in the multimeter s specifications Temperature changes inside the multimeter due to self heating may cause additional error on other ac voltage ranges The additional error is less than 0 02 and dissipates in a few minutes AC Current Measurement Errors Burden Voltage Burden voltage errors which apply to dc current also apply to ac current measurements However the burden voltage for ac current is larger due to the multimeter s series inductance and your measurement connections The burden voltage increases as the input frequency increases Some circuits may oscillate when performing current measurements due to the multimeter s series inductance and your measurement connections Low Level Measurement Errors When measuring ac voltages less than 100 mV be aware that these measurements are especially susceptible to errors introduced by extraneous noise sources An exposed test lead acts as an antenna and a properly functioning multimeter will measure the signals received The entire measurement path including the power line act as a loop antenna Circulating currents in the loop create error voltages across any impedances in series with the multimeter s input For this reason you should apply low level ac voltages to the multimeter through shielded cables You should conne
