7-4. Selecting a Weighing Unit

Press the MODE key to select a unit.
The following sections are a description of the
three common units: g (gram mode), pcs (counting
mode), and % (percent mode).

7-5. Basic Operation

1. Select a weighing unit.
2. When the display does not show zero, press the
ZERO/ON:OFF key to set the display to zero.
3. When using a tare (container), place the
container on the pan, and press the TARE
key to set the display to zero.
4. Place the object to be weighed on the pan or
in the container.
Wait for the STABLE indicator to turn on and
read the value.
5. Remove the object from the pan.
 The ZERO/ON:OFF
balance if the weight is within ±2% of the
weighing capacity around the power-on zero
point. The ZERO indicator
the weight exceeds ±2% of the weighing
capacity, the balance will not be zeroed.
 The TARE key will tare the balance up to the positive value corresponding to the
weighing capacity. In this case the NET and ZERO indicators turn on.
 The weighing range is from the zero point to the maximum weighing capacity.
When tared, weighing can be performed up to the weighing capacity minus the tare
value.
 When the ZERO/ON:OFF key (zero setting) or the TARE key is recognized,
the display turns off except for a weighing unit and the decimal point. The balance
waits for the weight value to become stable and then performs each function.
Precautions during operation
 Make sure that the STABLE indicator is on whenever reading or storing a value.
 Do not press the keys with a sharp object such as a pencil.
 Do not apply a shock or a load to the pan that is beyond the weighing capacity.
 Keep the balance free from foreign objects such as dust or liquid.
 Calibrate the balance periodically to maintain weighing accuracy. (Refer to
"9. CALIBRATION.")
