3.4 Main Operation Example
EC1000SA 3-33
3.4.9 Using measurement functions
The EC1000SA is equipped with the following measurement functions.
•
Voltage (RMS, average DC, peak)
•
Current (RMS, average DC, peak, peak hold)
•
Power (effective, reactive, apparent)
•
Synchronization frequency (external synchronization)
•
Load power factor
•
Load crest factor
•
Harmonic current (50 Hz/60 Hz fundamental, up to 40th harmonics)
Measured values are displayed in the measured value window MEASURE screen, which enables the
output status to be monitored.
a) Measured value window
Figure 3-13. Example of Measured Value Window (AC-INT Mode)
When a measurement is out of range, “
− − − − −
” is displayed in the numerical value field.
b) Select measurement display
Select among RMS, AVG, PEAK, or harmonic current as the measured current and voltage values to
be displayed.
