OPERATION
To turn the Indicator on, press and hold ON for two seconds. The Indicator
performs a display test, momentarily displays the software version, and
then enters the active weighing mode.
To turn Indicator off, press and hold Off until OFF appears.
Zero is set under the following conditions:
• Automatically at Power On (initial zero).
• Manually: press ZERO. (Scale must be stable and within the zero range.)
Manual Tare: When weighing an item that must be held in a container,
taring stores the container weight in memory. Place the empty container on
the scale (example 0.5 kg) and press the TARE button.
The display will show the net weight.
To clear the Tare value, empty the scale and press TARE.
The display shows gross weight (zero if scale is empty).
Weighing: Place the item to be weighed on the scale.
(Sample shown: 1.5 kg, Gross weight.)
Note: To return to the Weighing mode from Parts Counting mode, press
and hold Mode until WEIGH appears.
Verify the indicator: place a known mass on the scale and check if the
reading is accurate. If not, calibrate, using the Calibration Guide.
