Check Accuracy
1. Confirm that the size web
you’re working with is the same as the one
selected in your WX
’s display.
2. Before engaging the WX-1 instrument onto the web, zero the instrument
by holding
it in the same attitude you’ll be taking the readings and press
the “Enter” or “Zero” button. This will eliminate any small tare effects.
3. Take readings along the web. FOR BEST RESULTS ALWAYS TAKE
SEVERAL READINGS OF THE WEB TENSION BY DISENGAGING AND
THEN RE-ENGAGING THE INSTRUMENT FROM THE WEB ITSELF.
4.
Verify the tension value. For example, if your suspended weight is 40.0 lb.
your instrument should also indicate 40.0 lb. +/- the full-scale accuracy
percentage of the specific instrument model listed in Section 4, once
properly engaged to the web.
This procedure confirms the instrument’s
accuracy and it is now ready for use.
Note: Accuracy Specification: NOTE, ACCURACY IS MODEL
DEPENDENT.
For an instrument with a full-scale range of 250 lb., this
translates into +/- 5 lb., and for an instrument with a full-scale range of
500 lb., accuracy is +/- 10.0 lb. (with a 2% Accuracy Specification).
If you have additional questions, please contact Tensitron for help.
