| Indicación de error de polaridad | Cuando la corriente operativa (voltaje) alcanza más del 5% de la corriente nominal (voltaje) y el error excede el 180%, debe haber una indicación de polaridad. | |
| Nota: si es más del 10% de la corriente nominal de funcionamiento (voltaje), todavía no hay indicación de polaridad adecuada, lo que indica una falla. No aumente la corriente (voltaje) para evitar quemar el instrumento. | ||
| Indicación de error de relación variable | Cuando la corriente operativa (voltaje) alcanza más del 5% de la corriente nominal (voltaje) y el error excede el 30% pero es inferior al 180%, se debe dar la indicación de error de relación variable. | |
