Measuring DC Voltage
Set up your multimeter to measure DC voltage as shown in Figure 2-5. Probe the
test points and read the display.
Table 2-3
This multimeter displays DC voltage values as well as their polarity. Negative
NOTE
DC voltages will return a negative sign on the left of the display.
If you are measuring a signal which includes AC components and the peak
CAUTION
value is exceeding the measurement range, you will need to lock a range
that is greater than the peak of voltage. Use the maximum range of 1000 V
to check the signal condition, and manually select a suitable range for the
signal.
As the DC voltage measurement has the Normal (Series) Mode Rejection
Rate (NMRR) capability for 50/60 Hz noise, a hazardous voltage indication of
measurement range will automatically be set to a higher range, and the
analog bar graph will be varying fast or greater than the displayed value.
