DC current measurements
When you connect the multimeter in series with a test circuit to measure current,
a measurement error is introduced. The error is caused by the multimeter's series
burden voltage. A voltage is developed across the wiring resistance and current
shunt resistance of the multimeter, as shown below.
Figure 3-5
If you apply more than 5 A during current measurement, self-heating occurs in the
multimeter's 10 A shunt resistor and internal signal-conditioning component. Do
allow few minutes stabling time for better accuracy for current measurement.
After applying more than 5 A current measurement, do allow a few minutes for
heat dissipation to ensure better accuracy for other measurement.
