No safety, there is no fuses, missing PTC. This is only for low voltage and low current usage.
Glass or small fuse, a PTC. This can be used on mains voltage occasionally as long as there is a good fuse (Below 16A) before.
Ceramic fuses rated for marked voltage, PTC's and MOV or GDT, input are rated for at least 250VAC on ohm/capacity ranges. These meters will usual be fine for mains voltage, but may not be good enough for measuring on high current circuits (i.e. Industrial/distribution).
Pen shaped meter with one build-in probe and one probe lead.
Meter is a pocket meter, this means it is small and include a way to store the probes.
Small meter, it is less than 140mm long
Medium meter, it is between 140 and 170mm long
Large meter, it is between 170 and 200mm long
Very large meter, it is above 200mm long
Meter is clamp meter, i.e. designed clamp around the wire to measure current.
Meter is designed to stand on the bench
