10  RL-TA Series Operation Manual 

This operation is called “Tare” and “Net” is displayed while the weight of the pan is being set. 
 

After the weight of the pan has been set, if a sample is placed in the container the balance will display the 

weight (net weight). 
 

* When a tare range is set, the weighing capacity is reduced accordingly. 

Weighing capacity = original weighing capacity – pan weight 
 

Even after the weight of the pan has been set and the display is set to “0,” the value indicated by the bar 

graph includes the pan weight. 

 

4.5

 

Set a Gross Weight 

Press the Function key while the weight of the pan is being set. 

The gross weight, which is the sum of the pan weight and the weight 

of the sample put in it, is displayed. 

The B/G sign is displayed while the gross weight is being displayed. 
 
Pressing the Function key will toggle the display between net 

weight and gross weight. (Unit B, net weight, is also displayed if it 

has been selected.) 

 

 

1. 

A gross weight can only be displayed when the balance functions as a weighing machine. 

2.  When a gross weight is displayed, you cannot set a tare range. You can only adjust the 

zero-point

 

4.6

 

Single-touch Response Setting 

This function allows you to switch the response of the balance with a single touch of the Set button. 

The balance will be subject to different levels of vibration depending on where it is placed.    Adjusting the 

balance’s response according to the magnitude of vibration reduces the variation in its display and the time 

required for the display to stabilize. 
 
Pressing the Target key once displays the current settings ([

] etc.). 

Pressing the Target key again toggles the display between [

 

FASt

]. 

After the balance settings have been completed, the display automatically returns to the weighing mode. 

 

This function corresponds to the settings [

S

.

  rE.

  *] and [

.

   ENU.

  *] of Function 1,   

and the settings in Function 1 are also changed at the same time.
