Whether it is for diagnostic purposes or simply screening a bunch of batteries in storage, there are instances where it would be beneficial to test a single battery as opposed to the locomotive pair.

Ask Hapeman about custom screen programming for greater diagnostic and data keeping possibilities to suit your needs.
