P644x input leads/Repairs

3x10 pin probes

Logic probes with the 3x10 pin header configuration includes P6440, P6441, P6442, P6443 and P6444. These probes accept 3 lead sets in the form of a 10 pin connector.

These types of lead sets are very hard to find. Fortunately they are made with readily available parts that can still be bought today. They work just as well as originals and can be made for less then 4$ per connector.

Procedure

Most of the adapters are made out of 3M parts. The adapter consist of a 10 position IDC socket (3473-6000), a strain relief (optional) (6473-6000) and a socket pull tab (optional) (3490-1). A 430 Ω resistor must be placed in series between the ribbon cable and the connecting end.
