This appears to be the one you purchased.
It should have come with one black and one red test lead. Haven't ever seen a meter with two probes supplied the same colour. If you don't want to complain to SCA then you will have to identify one of the leads as black or red by colouring the appropriate lead with insulation tape or whatever. Com is black, amp or volt/ ohm socket is red. Amps is used only very occasionally. To cover metal probe so only tip is showing involves getting a piece of spare electrical wire, removing its plastic covering from the internal metal wire and then sliding it onto the metal probe. Think of it as a plastic tube. At worst you could use Sellotape to achieve the same result. Or you may not bother and just make sure your hands are steady when taking measurements.
