  • Page 10: Measuring Ac/Dc Voltage And Frequency

    Making Basic Measurements Measuring AC/DC Voltage And Frequency The non-zero display reading is normal when the meter test leads are open, but this will not affect actural measurement accuracy. The meter will show zero or close to zero when the test leads are shorted. In reading AC voltage or current, reading-settling time increases to several seconds at the low end of AC voltage and current ranges in rms models.

  • Page 12 Making Basic Measurements  Caution To avoid possible damage to the meter or to the equipment under test, check the meter’s fuses before measuring current. Use the proper terminals, function, and range for your measurement. Never place the probes across (in parallel with) any circuit or component when the leads are plugged into the current terminals When measuring current, the meter acts like an impedance such as 0.01Ω...
