4.5 Measurements

Standard measurements are always available through the

Meas

key on the front panel. These

measurements are spread across multiple screens to enhance readability. Switching between
these screens can be done by successively pressing the

Meas

button on the front panel. This

will cause the screen to cycle through all available measurement screens.

4.5.1 Basic

Measurements

The following three measurement screens are available:

Parameter

MEASUREMENTS 1

VOLTAGE

AC rms voltage

CURRENT

AC rms current

FREQUENCY Frequency
POWER Real

power

MEASUREMENTS 2

VA POWER

Apparent power

VAR POWER

Reactive power

POWER FACT

Power factor

CREST FACT

Crest factor

MEASUREMENTS 3

VOLT THD

Voltage distortion

CURR THD

Current distortion

PEAK CURR

Highest AC current found

PHASE

Phase angle (relative to phase A (ø1))

Note: The V and I distortion calculations are based on H2 through H50 with the fundamental
component (H1) in the denominator.

Measurements are always running in the background. When the user selects a measurement
screen for display, the AC source first updates all the measurement parameters before
displaying the requested screen. Consequently, pressing the MEAS key may not always bring
up the selected screen immediately. There will be a perceptible delay. This will prevent the
screen from appearing with invalid or blank readouts.

Note that all measurements are AC coupled only so any DC offset will not be reported.

4.5.2 Accuracy

Considerations

Any measurement system has a finite accuracy specification. Measurement specifications are
listed in Section 2. When using the AC source for measurement purposes, always consider
these specifications when interpreting results. Measurement inaccuracies become more
pronounced as the signal being measured is at the low end of the measurement range. This is
particularly relevant for low current measurements. The CS Series is a high power AC source
optimized for providing and measuring high load currents. When powering low power loads,
measurement inaccuracies on rms and peak current measurements will greatly affect derived
measurements such as power, power factor and crest factor.

The measurement system on the CS Series uses a digital data acquisition system with a 96
Ks/sec sampling rate and 16 KHz bandwidth. This means that higher frequency components of
the measured signal are filtered out. Any contribution to the rms value of voltage and current
