See the Master Bender app or MasterBender.com website for more information. * Standard Tool List * Safety - Safety manual and first aid. 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. MER includes key NEC tables from the National Electrical Code (NEC) 2011. Visit our website at MasterSparky.com for more information. If you like MER Lite, you will love the full MER.
