Average Hold Mode
1. Place the weighing sample on the weight indicator and wait until the sample has stabilized.
2. Press the ( ) key to start dynamic weighing. During dynamic weighing, the current
average weight appears on the display and then the dynamic weighing result is displayed with
the symbol HOLD. The weight indicator calculates the mean value from a hundred weighing
operations within AVGTM seconds.
3. Press the ( ) key again to go back to weighing mode. Or wait until the HOLDTM
minute.
Note: When the ( ) key is pressed for the first time, the weight indicator does not wait for
a stable signal. It is possible to press the ( ) key at the beginning. Then place a weighing
sample on the scale until the sample has stabilized (via setting MOTBAND). Start dynamic
weighing. During the dynamic weighing process, the current average weight appears on the
display and the HOLD symbol flashes. The scale calculates the mean value from a hundred
weighing operations within AVGTM seconds. Then the dynamic result is displayed with the
symbol HOLD.
Auto Hold Mode
1. While the net weight is within the zero “dead” band, the indicator shows the current weight.
2. Press the ( ) or ( ) key to clear any residual weight and return the scale to the

and the READY message alternately and flashes the HOLD symbol, if the weight moves inside
than the zero “dead” band.
4. Place the item to be weighed on the scale.
5. Once the weight moves outside the zero “dead” band and the signal is stable, the indicator
begins to calculate a long term average (selectable time, AVGTM) that compensates for any
movement in the mass. During the selectable time the signal must be stable, if not, time starts
again. The instrument flashes the HOLD symbol and shows the current average value.
6. The HOLD symbol is displayed when the final sample weight is shown on the display.
7. Press the ( ) key to force the sample to be re-calculated. Press any other key to go
back to the weighing mode.
