Also, any load cell system must be routinely checked for accuracy using
traceable weights as these types of systems are also highly inaccurate
and generally do not meet the minimum repeatable accuracy standards
required by ISO-17025.

Check Accuracy
1. Confirm that the size band
you’re working with is the same as the one
selected in your BTX
’s display.
2. Before engaging the BTX-1 instrument onto the band, 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 band. FOR BEST RESULTS ALWAYS TAKE
SEVERAL READINGS OF THE BAND TENSION BY DISENGAGING
AND THEN RE-ENGAGING THE INSTRUMENT FROM THE BAND
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 band.
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).

Calibrate Instrument
*IMPORTANT:
T
HIS FEATURE SHOULD ONLY BE USED BY A CALIBRATION FACILITY USING CERTIFIED AND
TRACEABLE DEAD WEIGHTS
.
D
O NOT USE THIS FEATURE FOR A SIMPLE ACCURACY CHECK
.
If you want to verify or check the accuracy of a calibration go to:
“Check
Accuracy” in Section 7: Advanced Operation.
When calibrating these instruments tension values must be entered in
Lbs. Note: If your dead weight standards are in Kilograms, convert their
values into Lbs: 1 KG = 2.2046 Lbs
