Hold

There are five different hold functions, you can choose the best option for you and set it 
the parameter settings 

1. Peak Hold:

 Grabs the highest weight 

(for materials testing, ie. tension and pulling 

force)

 

● Press the HOLD key then add weight to the scale

 

● The indicator will show the highest weight it recorded and hold it on the screen until 

a higher weight is placed on the scale

2. Manual Hold:

 Grabs the current weight and holds it so it will not change/fluctuate 

 

● While weighing, press HOLD and the indicator will hold the current weight on the 

screen until HOLD is pressed again

3. Auto Hold:

 If the weight on the scale is above 20d and is stable, the indicator will 

hold that weight on the screen for 3 seconds then go back to general weighing 

 

● Pressing the hold key is unnecessary, holding is done automatically when the scale 

is stable

4. Average Hold: 

Used for animal weighing, the indicator will display the average 

weight sampled from 1-9 seconds (Set in the 

HAt

 parameter setting)

 

● Add animal to scale and press HOLD

 

● Indicator screen will show “

LOC

” for 1-9 seconds, then display the average weight 

from those seconds

 

● Press HOLD again to exit holding mode

5. Auto Average Hold: 

Used for animal weighing, the indicator will display the aver-

age weight sampled from 1-9 seconds without the need to press the HOLD key.

If the weight on the scale is above 20d (scales division x 20) and is stable, the indica-

tor will start grabbing the average weight sampled from 1-9 seconds (Set in the HAt: 

parameter setting). In parameter 

Hadt

 you can set a determined loading time from 

1-9 seconds. This is the time you have to load the animal before the scale begins to 

take the average weight. 

 

● Add animal to scale. Once weight is added to the scale, the scale will wait the set 

loading time and then the Indicator screen will show “

LOC

” for 1-9 seconds

 

● It will then display the average weight from those 1-9 seconds for 3 seconds and 

then repeat the process
