Jap,
Actually we compensate the lack of high voltage inputs with a simple transformer circuit, the lack of high current by using a suitable shunt.
As the question of a second recorder cames uo I thought it was a good situation to look for high voltage inputs, so we don´t must rescaling the values.
Additional, a similar system like our old yokogawa, everyone knows how to work with.
Normally we use the yokogawa for dry heat running tests and only using the channels for temperature, this happens 4...6 times a year.
But now we got the new project and still the heat tests, therefore a second one is needed.
This reminds me, we got an elder Yokogawa DL

scopecorder with 16 channels, 6 are having HV modules.
But no temp inputs, no usb.
