Prometrix/KLA RS35/RS55 swapping DVM, Current Source, Analog I/O and PCA Relay board

Please follow this critical step when getting a board from GetSpares.com.  Please make sure you disconnect the battery connection on the analog power supply.    This applies to :

KLA/Prometrix RS35, RS55, RS75, Versaprobe VP10e 54-0005

These models have the following card part numbers:

36-0014 – PCB DVM CARD
54-0014 – PCB DVM CARD
54-0005 – Current Source PCB
54-0389 – Current Source PCB
36-0042 – Analog I/O Board
54-0252 – Analog I/O Board
54-0057 – Analog Power Supply
36-0004 – Current Source PCB
54-0006 – PCA Relay Board

Simply put, the battery connection should be disconnected during install to ensure that any voltage is not force on any pin which should not recieve power when unplugging the cards and the interconnect daughther cards.  Really, as long as you have This picture illustrates the key components where care must be taken:

Cards for RS35,RS55 and RS75 measurement cards

Please follow this simple step to protect the sensitive voltage supply, current source, digital voltmeter,  relay matrix boards from any accidental short while plugging in the interface cards.

Thanks for looking!
