The test probe may only be used for applications that are specified in the operating instructions for your test instrument. Make certain that the measurement cables are in flawless condition, e.g. no damage to insulation, no interruptions in cables or plugs. Measurements per DIN EN 61010-031 may only be performed in environments in accordance with measuring categories III and IV with the safety cap attached to the control unit’s test tip.

In order to establish contact inside 4 mm sockets, the safety cap has to be removed by prying open the snap fastener with a pointed object (e.g. the other test probe).

The safety cap must also be removed in order to attach the alligator clip with the bayonet lock included in the scope of delivery. After replacing the test tip, make sure that the new test tip has been screwed in all the way. Use a 5 mm hex wrench to this end. Each time the safety cap is reattached, it must audibly snap into place.
