Master Electrician Reference™
Master Electrician Reference™ (or MER™ for short) is your electronic pocket electrician reference guide.
MER™ is for electrical designers, engineers, installers, contractors, facility managers, inspectors, exam candidates, apprentices, electricians, journeymen, architects, and technicians. MER™ is for people doing residential, industrial, and commercial work. Simply, if you work with electricity, this reference guide is for you!
Have you ever lost pages or had damaged pages in your pocket electricians reference? The solution is here: Use MER™ to keep the most important information easily accessible on your iPhone, iPod Touch, or iPad. MER™ will even do calculations for you; something your old pocket reference book can't do. With a little practice, you can find reference material in seconds! Much faster than using most paper books!
Most pages contain a general scientific calculator. It is expression based: Just enter an expression and evaluate it. It understands trig and power functions, can convert between radians and degrees, and has built-in basic constants like pi and e.
