13.1.2 Anti-convection mode
If measurements have to be taken under unavoidable ambience conditions, (e. g.
changing air condition systems) convection occurring within the weighing space may
result in fluctuations in the display on the balance after the stability display has ap-
peared. The small range (readability 0.01 mg) of series ABT is particularly suscepti-
ble to this effect.
Anti-convection mode adjusts the timing of appearance of the stability mark. Note
that the stability mark will then appear at a late timing.
Repeatedly press the [CAL] key until "ConvECt" appears.
To set anti-convection mode, press the [TARE] key.
Setting of this mode can be confirmed only in settings check
display (see ch. 12.6).
13.1.3 High-stability Mode
The balances of series ABT are designed to react only minimally to the effects of
vibrations and drafts. However, if it must be set up in a location with poor conditions,
use this function to reduce the effects of vibration or air current even further. There is
a slight increase in the reaction time of the balance but the display itself is stabilized.
Repeatedly press the [CAL] key until "ConvECt" appears.
To set high stability mode, press the [TARE] key.
Setting of this mode can be confirmed only in settings check
display (see ch. 12.6).
