PR300– ✩★ᮀᮀᮀ – ᮀᮀ
<Model>–<Suffix code>
✩ : Returns the currently selected phase and wire system
1: Single-phase two-wire system
2: Single-phase three-wire system
3: Three-phase three-wire system
4: Three-phase four-wire system
5: Three-phase four-wire system (2.5 element)
★ : Returns the currently selected input range
