2. Rough handling.
3. Changes in work location.
4. Height above sea level.

To check the balance’s calibration, place a known mass on the center of the platform and read the displayed weight.
If the displayed weight differs from the known mass by more than acceptable limits, refer to the Calibration Menu and the Specifications at the rear of the manual.

Weighing
To weigh an item, place it on the platform and wait for the weight to stabilize. The weight will be displayed on the digital display.

1. Press “ON/TARE” to set the display to zero.
2. Place the object to be weighed on the platform.
3. Wait until the unit indicator appears before reading the displayed weight. When the unit indicator appears, the reading is stable.

Units exchange
The ES Series Electronic LCD Balance allows you to weigh items in different units of measurement. To change the unit of measurement, access the setup menu and select the desired unit.
Under weighing,press “OFF/MODE” to change the units.

Taring
To tare the balance, place an empty container on the platform and press the tare button. This will reset the weight to zero and allow you to weigh only the contents of the container.

When weighing samples that must be held in a container, taring enables the balance to subtract the weight of the container and display only the net weight of the sample.

1. Press “ON/TARE” with no load on the platform to set the display to zero.
2. Place the empty container on the platform. Its weight will be displayed.
3. Press “ON/TARE”. Zero will be displayed and the container’s weight will be stored in the balance’s memory.
