„STABILITY“
The value set for the stability control depends on the quality of the balance location and must be correctly
chosen in order to obtain optimum, reproducible results. Choose:
– Optimum balance location: „STABILITY LOW“
– Good balance location: „STABILITY MEDIUM“
– Critical balance location: „STABILITY HIGH“
„AUTO-STANDBY“
The Auto-Standby mode turns off the balance automatically, if:
• the balance is tared and has shown “Zero” for at least 5 minutes
• the balance has received no remote control command via the interface for at least 5 minutes,
• the automatic zero correction „AUTO-ZERO” is activated.
It is possible to re-start the balance after it has been switched off by an automatic Auto-Standby:
• Briefly press any key
• Put a weight on the balance
• Make a remote control command via the interface
„AUTO-ZERO“
If the automatic zero correction „AUTO-ZERO” is activated, the balance always gives a stable zero (e.g. even
with fluctuations in room temperature).
