CAT III 1000 V CAT IV 600 V safety rating

The decisive specification is the dual safety category rating of CAT III 1000 V and CAT IV 600 V. This rating determines whether the probe can be safely used on the installation category and voltage level of the specific measurement task. Always match the probe category to the environment and the meter category to maintain the protection level.
