What is calibration and how do I calibrate my Tally Pro?

Scale calibration is the process of testing a scale, to ensure the level of accuracy you require. 

Over time you may notice the accuracy of your readings diminishing with routine use. Calibrating periodically using a 50g ASTM Class 1 calibration weight will ensure you maintain optimal accuracy and precision. 

Follow the steps below to calibrate your Tally Pro Precision Scale:

• In Weight mode, press both the Dial and the Timer Button for approximately 3 seconds.
• Follow instructions on the screen to complete scale calibration.
• When the screen prompts: “Begin calibration?”, select the desired response by turning the dial clockwise/counterclockwise and then press the Dial or the Timer Button to confirm the selection.
• When the screen prompts: “Place 50 g Weight”, place 50 gram weight on the center of the scale weigh pan.
• The screen will display an animation while the scale is going through calibration.
• Once calibration is complete, the screen will return you to your previous mode.
