Measuring Correctly

Getting the Correct Data the First Time!

When taking measurements in the field it is always important to check the calibration of your equipment to make sure you are being accurate.  Scales, thermometers, and other equipment over time may stray out of acceptable limits of accuracy.  I see this often as folks weigh chickens on a dairy scale that they adjust to read zero.  What is more important?  What the scale reads when loaded or empty.  Keep a standard object to weigh to check your scales before walking into that house.  Any object that will neither loose nor gain weight will work.  Check your object at either at the post office or at the weights and measures office in your locality.  An ice water slurry will work for most thermometers that can be calibrated.  Also, just because the instrument is digital, doesn't always mean it is accurate.  Check the manufactures manual for more information on your instrument.

  3. Keeping an accurate scale is important if you make decisions such as when to market a flock, or figuring out if pullets are at adequate weight prior to housing, etc.
