Tare function

When switching on the tare function, the instantaneous measured value is set to

zero. In this case, measurement is continued with this offset. By switching off the

tare function, the actual measured value is displayed again.

Tare can be activated during configuration (

Sample&hold amplifier

With the sample & hold function activated, the measured value is held on the dis-

play. By switching off the sample & hold function, the actual measured value is

displayed again.
