| The current ZOOM meters come
standard with a small state-of-the-art UNIVERSAL adapter fully reliable to allow
use of ST, SC, FC or any 2.5 mm patch cables as test cable which saves money
on consumables (test cables wear out). Sorry physics and optics do not
allow the same universal connector to work well on any brand of the light
source. Hence, light sources must have ST, SC, or FC connector ports. |
