Amput digital pocket scales are portable LCD scales. They are used for weighing small objects, such as jewellery, letters or individual servings of food. The pocket-sized scale is designed with a touchscreen, and can be taken with you wherever you go. As the scale is moved around, transported, and routinely used, the accuracy of the weights can become slightly inaccurate. Calibrate the scale regularly to ensure the scale weight is accurate.
Remove anything placed on the scale. Set the scale on a level, sturdy surface.
Press the "On/Off" button to turn the Amput pocket digital scale on.
Hold down the "Mode" button until the display screen says "CAL." Press the "Mode" button again so "CAL" begins to flash on the display screen.
Place the calibration weight on the scale. Every Amput pocket digital scale is sold with a calibration weight that correlates to the maximum weight that the scale can measure. For example, a 500 gram scale is sold with a 500 gram calibration weight. If you are unsure of your scale's weight, locate the sticker on the bottom of the scale. There should be a line that looks like this: AMPUT Pocket Digital Scale 100g x 0.01g. In this example, "100g" is the weight. AMPUT weights can be 50g, 100g, 200g or 500g.Nickels can be used in lieu of weights; a single nickel weighs five grams.
Remove the weight from the scale once the calibration weight displayed on the screen changes to "0.0." If the display screen states "ERR," there was an error in sensing the weight. Repeat the calibration process.
