Making a DC Volt Measurement
This procedure will show you how to make a DC measurement with the DMM.
DC voltage measurements are made by connecting to pins 6 V+ and 1 V– of the
D-sub connector.
Do the following to perform a DC voltage measurement on the DMM:
1. Select the DMM:
INST:SEL DMM
2. Configure the DMM to take a DC measurement in the 30 V range with
minimum resolution:
CONF:VOLT:DC 30, MIN
3. Initiate the measurement:
INIT
4. Retrieve the measurement results:
FETCh?
Making AC Volt Measurements
AC voltage measurements are made by connecting to pins 6 (V+) and 1 (V–) of
the D-sub connector. The following measurement example is AC coupled. Any
DC component is blocked.
The default range change time for AC measurements is very slow, approximately
2 seconds, to permit accurate measurements of low frequencies (below 100 Hz).
If you know the frequency you are measuring is above 100 Hz, you can use the
SENSe:BANDwidth command to speed up range changes and autoranging.
60 Hz may also be measured in the Fast Bandwidth Mode if an additional .3%
error is added to the accuracy spec.
1. Select the DMM:
INST:SEL DMM
2. Configure the DMM to take a AC Volt measurement in the 30 volt range
with minimum resolution:
CONF:VOLT:AC 30, MIN
