Good afternoon guys. High Voltage Hello!
Thanks for the feedback.
High Voltage! I need your help.
It takes you a little time. I'm sorry.
Advantest R6144 has one element in which I doubt.
This is the R35 SIP RESISTOR ie the resistive matrix.
I want to ask you to measure her resistance.
R35 it is necessary to unsolding (do not overheat) and measure its resistance
between the terminals:
PIN to PIN.
1-2, 1-3, 1-4, 1-5, 1-6.
2-3, 2-4, 2-5, 2-6.
3-4, 3-5, 3-6.
4-5, 4-6.
5-6.
I am give You an example of table. I have doubt in my first section.
Please write Your result in the table.
Later I will send you for comparison my measurements of the first section. It is important. It's a divider!
The accuracy of the calibration and the readings in the lower orders depend on it.
And yet you have on the analog board from the side of soldering on the resistor R56
Two diodes connected to each other are connected in parallel.
Question: what is their marking???
I have not installed them, and I bought a new Advantest R6144.
I will be very grateful to you!
All the best! 3G57.
A few screens from the last my calibration(2016):

If You have a questions - ask me, please.
HV I will wait for Your reply.
Best regards.
