Things You'll Need
- US-Magnum 1000XR jewelry scale
- 500-gram standard calibration weight
Manufactured by US Balance, the US-Magnum 1000XR digital pocket scale is a lightweight, precision scale. It offers six weighing modes: grams, ounces, grains, pennyweight, troy ounces and carats (the units of weight most commonly used to measure precious metals and gems, such as gold, silver and diamonds). The scale has a back-lit LCD screen, stainless steel platform and grooved weighing tray. Powered by 3 AAA batteries, it features an energy saving mode that shuts off the unit after 60 seconds of inactivity. The scale has a maximum capacity of 1,000 grams (1 kilogram).
Place the scale on a flat, stable surface. Press and release the "On/Off" button. Press the “CAL” button. When the display reads “500.0,” place a 500-gram calibration weight on the platform. If the display reads “Pass,” the unit is properly calibrated and ready for use.
Place the weighing tray on the platform. Press the “Tare” button to return the scale to “0.0”. Place the object to be weighed in the tray. Remove the object and tray from the scale and press “Tare” to cancel the tare function.
Change weight modes by pressing the “Mode” button until the desired weight measurement unit is indicated on the display.
Count 10 pieces or small items and place them on the platform. The weight will be shown on the LCD display. Press the “PCS” button and hold for three seconds. The "Parts Counting Function" is now active. Remove the objects. The display should now read “0.” A large number of items may now be counted by weight, instead of by hand counting, thus saving time and removing the element of human error. Their total weight may not exceed 1,000 grams.
Extreme temperatures may affect the operation of the scale. Ideal operating temperature is 50 to 86 F (10 to 30 C).
Dropping the unit or improper handling may damage the internal sensor.
Avoid using the scale near magnetic fields.
