PPA5xx/15xx user manual
2-2
The PPA5xx/15xx has a universal mains input and accepts
any supply voltage from 90-265Vrms at 50 or 60Hz.
Note: If the power is cycled “off-on” within a 10 second
time period, the message “Turn power off for 10 seconds”
appears. A 10 second power off window allows all micro
controllers to fully reboot and prevents any errors during
the power on sequence.
Switch on the PPA5xx/15xx. The display should illuminate
with the model name and the firmware version for a few
seconds while it performs start-up checks. It should then
default to the power measurement display. Note that the
switch-on message can be personalised – see the User
Data section under System Options.
The screen is a 4.3” (110mm) LCD colour display. There
are no manual adjustments as the display should be clear
and visible in all lighting applications.
The PPA5xx/15xx features a low value blanking option
which when enabled will cause all parameters that are
measuring very low values (for example noise detection on
the test leads) to display 0.0000. See section 6.2 for more
details about this option.
Allow 30 minutes warm up time before commencing any
tests to ensure accurate readings.
The voltage and current leads may now be connected to a
circuit under test. The high common mode rejection ratio
(CMRR) of the instrument allows the current channel to be
connected in the live path (high side shunt) instead of the
neutral path (low side).
The test leads supplied meet the safety requirements of
BSEN61010-1 to an operating voltage of up to 1000V rms
cat II or 600V rms cat III.
