Determining the best megapixel setting on your digital camera is
not easy. Bigger is not always better; especially when the photos are
going into a document such as an inspection report or on a website. Photos
that are displayed smaller than their actual size on websites will not look as
good as they would if they were displayed at their actual size. Photos
that are too large will bloat the file size of inspection reports. A large
number of oversized photos that are being displayed smaller than their actual
size can cause PDF software to distort or otherwise incorrectly display the
photos.
You can avoid these problems by selecting the
proper megapixel setting on your camera for the desired photo size. The
BestInspectors.Net Digital Photo Calculator makes it easy to determine the best
setting. The program includes both a calculator and reference charts so
you can see the relationship among the three key variables: physical size,
megapixels, and resolution.
Version 20 Easy
to understand and use Most home
inspectors and many experienced electricians guess at the electrical service
size requirements using rules of thumb (usually involving only square footage).
With the rapid growth in the number of electrical appliances and electronic
equipment during the past few years, making a guess could be a costly mistake.
The Residential Electrical Service Size Calculator takes the
guesswork completely out of determining the electrical service size requirement.
The Calculator requires no special knowledge of electrical systems or codes.
All you do is make basic observations about the house and fill in the blanks.
The Calculator lets you enter electrical loads in either Amps or Watts.
the required information can almost always be found on the nameplates of
appliances and mechanical equipment. The Calculator will tell the "Demand Load" (a trade term,
different from "connected" load), the nearest standard size panel and main
breaker, the conductor (wire) size and the conduit size.
The Calculator's worksheet can be filled out in about three to
four minutes and can be included with any inspection in PDF format.
Features of the Calculator: NOTE: This
worksheet is intended to be used as a general guide. It does not account for
all possible factors involved in determining the size of an electrical service.

The calculator is essentially an Ohm's Law
calculator. The difference between the
BestInspectors.Net
Voltage, Current and Power calculator and most Ohm's Law calculators is that
Ohm's Law calculators are usually geared toward electronics, not power systems.
This calculator is for power distribution systems. The calculator has a
Power Factor component to it. Most Ohm's Law calculators do not.
Calculations can be performed quickly and easily using name plate data or actual
measurements. The calculator is also a training
calculator. There is a list of relevant electrical terms and units of measure
on the screen at all times. Every time you enter a value, the related terms are
highlighted. Once you have entered the values needed to complete the
calculations, the remaining input fields are blacked out so you don't
inadvertently enter a conflicting value. For example, if you have entered
Voltage and Wattage values, the Current input field is blacked out so you can't
insert an invalid value. The Current in this case would be among the calculated
values in the results section. |
