Press
【
Aperture
】
and choose the number of power-line cycles (PLCs) to
use for the measurement. Selecting 100 PLC provides the best noise
rejection and resolution, but the slowest measurements
5. Autozero setting
Press
【
Auto Zero
】
to enable or disable this function. Autozero provides the
most accurate measurements, but requires additional time to perform the
zero measurement.With autozero enabled (On), the DMM internally
measures the offset following each measurement. It then subtracts that
measurement from the preceding reading. This prevents offset voltages
present on the DMM
‟s input circuitry from affecting measurement accuracy.
6. Set the relative value (Optional operation)
Press
【
Rel
】
to open or close Relative math function. When it is opened,
the reading displayed is a value which comes from the result of actual
measurement value subtracts the relative value that has been set. The
default relative value is the measurement value when the function is
opened.(P
lease refer to “ Math Functions”
in Chapter 2 to know about the
details.)
7. Read the measurement value
The multimeter measures the input signal according to the current
measurement settings and displays the measurement result on the
screen.
8. Make math operation (advanced)
You can perform math operation (Statistics, Limit and REL) on every DCI
measurement reading. For details, please refer to “
Math Operations
”.
9. Display the graph (advanced)
You can analyze the measurement data by using
“Bar Meter”, “Trend
Char” or “Histogram display”. For details, please refer to “
Display Mode
”.
