### 1/5 — MotorRate

*2012-05-05*

Pretty handy quick reference tool, however I would like it to include
Dials for:
Motor Efficiency
Motor Power Factor

Why do I get different answers between the dial screen and the manual screen when I use the same voltage, frequency, power, PF, Efficiency ??

### 5/5 — Amp settings

*2012-03-17, version 1.0*

Grand app ! Can you put single phase on as well and star delta ? O/L settings are allways a problem !

### 5/5 — Brilliant tool

*2012-03-12, version 1.0*

A must have for any sparky
