User Manuals & Product Sheets
Are the scales completely assembled?
The majority of scales are completely assembled. Some scales may require very minor assembly.
The dial I just installed rubs against the pointer. What should I do?
Check to see if the pointer has scratched the new dial. If it has, discard it and replace it with a new one. If not, remove it and reinstall the dial. Remove the dial and start over following the instructions provided.
The reading on my scale fluctuates, how can I resolve this?
The scale should be situated on a flat, level, and stable surface. The scale platform should be securely fastened to the scale sub-platform. The scale can be affected by electrical and RF (Radio Frequency) interference. Operation near power transmission lines is not recommended. Operation near appliances which switch on and off with heavy currents (letter openers, copiers, microwave ovens) is not recommended. The recommended operating temperature for the scale is room temperature (around 77 degrees Fahrenheit ). Allow the scale three hours to adjust to a the new climate if the scale was stored in a location a hot/cold environment. If the scale is to be operated in environments above or below room temperature, it is recommended that the scale be re-calibrated in that environment after a three hour adjustment period.
