FBPT-MIL-2CPA when is this tip required?

When testing M38999 connectors, with a Viavi fiber inspection scope, is the FBPT-MIL-2CPA required in addition to the the FBPT-MIL-2S and 2P inspection tips?

FBPT-MIL-2CPA is only required if the customer has a Glenair Test Probe/Adapter to work with the M38999 connector they are inspecting. The FBPT-MIL-2CPA is not a guide, but a tip that works with "guides" (Test Probe Adapters) made by Glenair.
