Auto Zero

The Auto Zero function allows a zero calibration to be initiated automatically under the
following conditions.
• the auto zero input (TB1-9/10) is in a closed state; jumper or remote switch
• the load is less than 2% of the design load
If the resulting zero deviation is less than an accumulated 2% from the last operator
initiated zero, the auto zero is accepted.
If the deviation is greater than an accumulated 2%, an E9 error is displayed and the relay,
if so programmed, goes into alarm (refer to
error is cleared after five seconds.
If material feed resumes during an auto zero function, the totalizing function is
maintained.
