Interrogation and extraction of information resulting
from a test log in a specified time scale and at a set
speed
Instruments internal memory selected for data
storage, this offers the fastest performance
Utilises 1GB internal memory
External USB memory stick selected for data storage
Application function to be selected
Using the Normal Application the default settings
within the instrument will be applied to all
measurements, useful for general measurements
All default parameters will be selected when “ENTER”
is pressed
The nature of the waveforms in a PWM motor drive
application makes measurement of the fundamental
frequency difficult. The application mode for PWM
motor drives applies a selectable filter which is a
parallel digital filter and will not affect the bandwidth
of the instrument; it is only used for frequency
detection. The best filter to use for a given application
should be selected by experiment. The filter does not
change the measured data at all. PWM application
mode also allows torque and speed to be
simultaneously measured so that efficiency can be
computed
All default parameters will be selected when “ENTER”
is pressed
Pre selectable filter options 64Hz, 250Hz, 1KHz,
4KHz, 16KHz, 64KHz, 250KHz
Select which parameter frequency reference will be
detected from input signal
Can be selected as On or Off if “On” is selected
manually enter the minimum frequency required
Power Measurement function can be set to disabled or
enable to measure the desired function from
analogue, pulsed speed, pulsed torque, or pulsed.
Once enabled a scale factor / offset will require
setting in relation to either Voltage or Frequency
(Not applicable to the PPA5510) Efficiency can be
measured between selected channels from the drop
down menu
