Measuring DC and AC Voltage

Key points:

 You must insert the voltmeter leads across the two points in a circuit for which you

want to measure the voltage. Use the red and black input jacks as shown below.

 You can use the rear panel red and black input jacks also (be sure to select front or rear).

 If you use front and rear, you can easily and quickly select one of two voltages.

 The DMM will Autorange, unless you override it by selecting a range.

 You can choose the number of digits displayed, using the DIGITS buttons.

 Be sure to select DC V or AC V, as needed.

 AC voltage displayed is the true RMS value of the waveform.

 AC voltage is accurate to less than 1% up to 100 kHz.

 Input impedance for AC V is 1M Ω in parallel with 100 pF (not including test leads).

 Input resistance for DC V is 10M Ω, unless changed to 10G Ω ! for 100 mV, 1 V, & 10 V
