Basic Operation (Gram Mode)
For the EJ-54D2, when the carat pan provided with
the balance is used, remove the weighing pan and
place the carat pan directly on the pan support.
1. Select a weighing unit.
2. When the display does not show zero, press the
RE-ZERO key to set the display to zero.
3. When using a tare (container), place the container
on the weighing pan, and press the RE-ZERO
key to subtract the tare weight.
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.
When the display hold function is enabled in the
function setting mode, the HOLD indicator turns on.
5. Remove the object from the pan.
The RE-ZERO key will zero the balance if
the weight is within ±2% of the weighing
capacity around the power-on zero point.
The ZERO indicator turns on. When the
weight e2% of the weighing
capacity, the balance is tared to zero. In this
case the NET and ZERO indicators turn on.
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.
