GS38 covers the leads, probes and clips. The instrument itself is BS EN 61010. Do not say GS38 covers the whole unit, because it does not.

What they look atWhat it has to be
Flexible leadsNo nicks, cuts or splices. Not stiff. Nothing missing. Length does not matter — flexibility does
Exposed probe tip2 mm to 4 mm. 2 mm preferred, 4 mm the maximum
Spring-loaded probesPreferred — the shroud pushes back as you press into a terminal
Finger guardsMust be in place. Missing or cracked, do not use them
Test lampsMust light. If they do not, there is a problem with the tester
Fused leadsIf yours are fused, the fuse inside must be high breaking capacity
✋One old habit to drop before you walk in. Testers once looped the lead behind their neck to keep it out of the way. Do not — and definitely not in your assessment. Keep it clear of what you are doing.
