After purchasing the PPK2, I connected the Fluke287 and PPK2 Ampere meter in series to check whether the measured values matched the Fluke equipment.
The Fluke287 consistently checked 37uA, but the PPK checked about 3uA, so the difference is too big. What is the reason?
I can`t take picture so I attached the circuit diagram I tested.
in this case, Fluke287 consistently checked 37uA but PPK2 checked about 3uA.
so... I tried another simple test.
When I use 1Mohm, Fluke checked 1uA that is correct.
but PPK2 checked 500nA ~ 800nA shaked that is incorrect.
When I use 1kohm, Fluke checked 1mA that is correct.
but PPK2 checked 25uA. it`s too low.
is there something wrong with the software setting? All the settings in the PPK2 software are default
Hi Jooyeol,
Thanks for sharing the information.
I'm not sure if this is related to the connection or Power Profiler configuration. Could you verify using the following connection and configuration:
Another possibility is that the PPK2 itself has an issue. If possible, could you try with a second unit to confirm?
Best regards,
Charlie
