    • 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.

    • What is a load cell?

      A load cell is a mechanism in the scale which bends slightly when weight is put onto the platform.The microcomputer in the scale measures the amount of bending and translates that into the digital display, which is the weight.

    • What does the term overload" mean in relation to my scale? "

      Overload" can have different meanings, all having to do with a weight that is too high. It may mean the weight placed on the scale exceeds its capacity, such as putting 15 lbs on a 10 lb scale. On a rate-calculating scale, it may mean you are trying to perform a function which cannot be performed with the weight registered on the scale, such as attempting to send a 5 lb letter using a service restricted to 1 lb letters. Symbols of overload include OVLD and OOOO. "

    • Can mechanical postal scales be calibrated?

      Mechanical scales cannot be calibrated.The only adjustment that can be performed is to manually align the position of the pointer with the zero weight mark using the Zero Adjustment Knob.To locate the Zero Adjustment Knob, please consult the users guide for your particular scale.

    • Can I wash my scale?

      We do not recommend that our scales be submerged in any type of fluid. You may clean the tray of the scale with a mild cleaner.

    • How do I know if my scale is weighing accurately?

      The only sure way to determine if your scale is weighing correctly is by placing a known weight on the scale. Examples ofa known weight" would include a piece from a precision weight set, or perhaps a measured weight used for exercising."

    • Do any of the straight weigh scales indicate how much the postage/shipping charges will be for my package?

      Straight weigh scales only weigh items, they don't calculate postage or shipping rates. However, USPS, UPS, Fed Ex, and DHL offer rate calculators on their website. You will be able to display the cost of shipping your package with this tool.

    • What cable(s) do I need to connect my downloadable scale to my PC so I can download the rates?

      A special cable that came with the scale is used to connect it to your computer. On one end there is an RJ-11 connector (which looks like the end of a phone cord). This plugs into the back of the scale. On the other end is a 9 pin serial connector. This plugs in to a serial port on your computer.
