- Page 9 PM100 / 300 U ANUAL ETTING TARTED With the analyzer connected, and with power applied, the default display shows Volts, Amps and Watts. On a PM300, quantities for 3 channels and sum are shown. The green LED on the front panel is illuminated when the analyzer has detected a stable fundamental frequency.
- Page 10 PM100 / 300 U ETTING TARTED ANUAL FREQ Frequency The frequency of the input waveform is obtained using the [FREQ] key. The lowest of the frequencies detected on the Channel 1 V and A inputs is displayed. This frequency is used as the fundamental for harmonic analysis.
- Page 11 PM100 / 300 U ANUAL ETTING TARTED Four further types of measurement are available. These are associated with only specific basic measurements. Attempting to show ‘VA’ ‘PEAK’ for example will result in a parameter error. PEAK Peak value of the waveform V pk, A pk.

- Page 19 If in doubt, enter ‘200’ Amps when prompted, and then reduce this value to improve resolution and accuracy. When using the inrush current mode on the PM100, it is advisable to first set manual range as describe on page 12 to monitor the signal before the inrush mode is issued.
- Page 20 MENU S PM100 / 300 U YSTEM ANUAL To give the best measurement accuracy, it is recommended that the Voltech Ballast CT (current transformer) be used where high common mode voltages are present. PM100 PM300 Electronic Ballast Tube Harmonic Mode Harmonic Amplitude may be displayed as a percentage (%) of fundamental or in RMS terms as desired.
- Page 21 This mode may be used to average measurements over a long interval from 10 to 300 seconds. Normally, the PM100 samples the waveforms at 200kHz and updates the display approximately every ½ second. This is ideal for most measurement applications.
- Page 22 MENU S PM100 / 300 U YSTEM ANUAL Disable Blanking Normally, small signals which are below the specified range of the analyzer are not displayed. The display is 'blanked'. To view small signals, disable the blanking by selecting ' '. For best accuracy, however, bring the signals into the normal operating range of the analyzer.

- Page 25 A measurement of the average input power is required to check the rating of the power supply. With default settings, the PM100 makes measurements at high speed and updates the display approximately every ½ second. With the waveform above, the measurements are not stable, and the analyzer pauses while it auto-ranges in between readings.
- Page 26 5. Press [MENU] again and the analyzer will now begin to make measurements. The red PROG led will flash to indicate that the PM100 is in long averaging mode. The display update rate will vary with the averaging time, but the analyzer is making continuous measurements and averaging them together.
