| Indikasyon ng error sa polarity | Kapag ang operating kasalukuyang (boltahe) ay umabot sa higit sa 5% ng kasalukuyang rate (boltahe) at ang error ay lumampas sa 180%, dapat mayroong indikasyon ng polarity. | |
| Tandaan: kung ito ay higit sa 10% ng rate ng operating kasalukuyang (boltahe), wala pa ring tamang indikasyon ng polarity, na nagpapahiwatig ng isang pagkakamali. Mangyaring huwag taasan ang kasalukuyang (boltahe) upang maiwasang masunog ang instrumento. | ||
| Indikasyon ng error sa variable ratio | Kapag ang operating kasalukuyang (boltahe) ay umabot sa higit sa 5% ng rate na kasalukuyang (boltahe) at ang error ay lumampas sa 30% ngunit mas mababa sa 180%, ang error indication ng variable ratio ay dapat ibigay. | |
