A megger Mega Ohm meter. You have to remove the device from service, and insure the megger can approach the voltage needed to activate the SPD.
But, there are only a couple types of SPD's, calibrated wires in a can of calibrated sand, or a can of Varistors (MOV) .
And, most SPD's are a one-shot, use it once and then replace it, The simple act of testing it, can damage it. So generally, rely on the mfgs test data, and replacement
guide,
Here's an article about testing MOV's http://www.digikey.com/en/pdf/l/litt...aristortesting
Be careful, above 250V, you are dealing with lethal stuff - even from a test set,Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
