| Configuration | Safety Category | Rated Voltage | Application Scenarios |
|---|---|---|---|
| With black protective cap installed | CAT IV 600V / CAT III 1000V | 600V (Main power inlet) / 1000V (Distribution cabinets, motor circuits) | Industrial power distribution, cabinet primary circuit testing |
| Without protective cap (bare sharp probe) | CAT II 1000V | 1000V | Household outlets, secondary circuit testing inside equipment |
💡 Category Explanation: CAT IV > CAT III > CAT II. Higher categories deliver stronger protection against transient surges and short circuits. Always fit the protective cap for high-risk primary power measurements.
