Selecting a Weighing Unit

 

 

Press the    UNITS    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).

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.
