Default Nervous RGB levels during KRP-500A calibration

Hi,

I'm trying to calibrate my Pioneer KRP-500A, but I'm having difficulties getting stable readings. The RGB levels keep jumping up and down. I made a video of the phenomenon: https://youtu.be/J_ss2vn7fq0

The phenomenon gets worse when I make some RGB drive or cutoff adjustments. Sometimes one color level completely disapears with one reading and jumps back to 50 another reading.

I'm using an i1 Display2, but a Spyder2 shows the same phenomenon. Before calibration I warmed up the tv for 60min with the i1 attached. The tv is patched and set to ISF-night mode.

Does anyone know what could be the culprit?

not much movement but also, how old are your meters?

The meters are pretty old I think, I acquired them secondhand. Do you think this kind of movement is normal?

I am not sure I trust the meters, also what version of the calibration software, is that a few years old?
