Answer first: A usable clamp meter for parasitic drain uk jobs is one that resolves small DC currents after a clean zero—so you can hunt modules without treating every microamp as gospel.
Parasitic drain hunting is patience work. The meter should not invent a drain through poor zeroing.

Frequently asked questions
Can a clamp replace pulling the negative battery cable?
Often you can measure drain on a cable without full disconnect, but confirm your method and vehicle guidance.
What drain is 'too high'?
It depends on the vehicle and modules awake; compare against the manufacturer baseline, not a forum number.
Why DC zero first?
Residual offset on a DC clamp can look like a phantom drain.
CAT rating note?
Match meter and leads to the circuit class you are entering—do not assume CAT III marketing covers every under-bonnet point.
