Ohaus, Corporation
Bench/Counter Scale
Load Cell Electronic
Model: Champ Square Scale CQ Series
Application: For use in general purpose weighing applications.
Identification: The required information is on a label glued to the frame of the scale under the platter.
Sealing: The device is sealed at the indicating element as per the Certificate of Conformance for the particular
indicating element used.
Test Conditions: The Champ Square Scale consists of a Champ Square Platform interfaced to either Ohaus
Indicator Models CD11, CD31,CD33, or CW11. The test conditions for the Champ Square Platform are
repeated here for reference: The emphasis of the evaluation was on the device design, marking, operation and
compliance with influence factor requirements. The Ohaus Champ (10 kg and 500 lb) weighing elements were
interfaced with Mettler-Toledo Hawk (Certificate of Conformance number 99-054) indicators and submitted for
evaluation. Several increasing/decreasing load tests and shift tests were performed. The devices were tested
over a temperature range of -10 o C to 40 o C (14 o F to 104 o F). A load of approximately one-half capacity was
applied to the bases over 100 000 times (each). The scale was tested periodically during this time.
The results of these evaluations and a review of technical information supplied by the manufacturer indicate the
device conforms to the applicable requirements of NIST Handbook 44
