Check your speedRated the Top Electrical and Electronic Engineering Tool for Palm OSFor figuring everything from Ohm's Law to VSWR, nothing else even comes close. Try the free trial of Electrist and see why electronic engineersin some of the finest R&D laboratories in the world, industrial maintenance crews, power utilities, RF & audio engineers, circuit designers, telecom engineers,Ham operators, electronics hobbyists, and fanatical Do-It-Yourselfers - among others - love this software. With a user interface, features, and formulas found inno other software backed up with world-class customer service, it's no wonder!Even though it's the finest formula calculator by a long shot, it's even more than that. Electrist does seamless NEC ampacity look-ups toautomatically give you the correct wire and cable sizes for any application - in both the AWG and Metric standards. You can also input any conductor's size,length, and material properties - from PCB traces to busbars - and accurately find the voltage drop.Sizing 3 phase panels & transformers is also a snap with the built in load calculator. Enter any number & configuration of delta or wye/star and3 phase, line-to-line, line-to-neutral, and/or centertap-to-neutral to instantly get both the phase and line loading in current, true power, and apparent power.The most complete set of calculations - Hundreds of formulas & variations:Integrated Ohm's Law/Watt's LawResistor Color CodeSeries/Parallel Resistance/Inductance/CapacitanceUnknown Value of Parallel Resistance/Parallel Inductance/Series CapacitanceVoltage/Current DividersCapacitive/Inductive ReactanceSeries/Parallel Resistive/Inductive/Capacitive Impedance - in parallel, series, and as currentPeak/Peak-to-Peak/RMS/Average Sine Wave ConversionWavelength/Frequency/Period/VelocityDelta/Wye ConversionRC/RL Time ConstantdB Power/Voltage Gain/Attentuation, dBu,dBm,dBW,dBuV,dBV Decibels (with either equal or unequal impedances)VSWRResonant FrequencyPeriodic WavesConductor Voltage Drop (single or parallel conductors)Conductor Size Selection (single or parallel conductors)3 Phase Load Balance3 Phase Voltage Unbalance - both NEMA and IEC negative sequence3 Phase Power - active, apparent, & reactive powerPower Factor CorrectionCost of UseThe easiest, fastest, and most advanced user interface available:Use AWG, Metric, and custom conductor sizes (such as defining PCB trace or busbar sizes)Create custom conductor materialsCalculate ANY parameter of most formulasEffortlessly scale values from 1 pico- to 1 Tera- rangesUnique scale-lock control keeps value displayed in selected rangeEnhanced Clipboard makes your work even easier and faster:Cut & Paste full unscaled valuesDirect access with functions assign, add to, subtract from, clear, and invertEach formula clearly displayed at the top of each formMap functions to any of the hard keys and navigator buttonsBuilt-In MiniCalc not only performs all the functions of a common calculator, but also many conversions useful to electrical professionalsFully compatible with any Palm OS device from system 3 to 6 whether color or monochromeFree upgrades and E-Mail customer service and support for life
