AZ Absolute zero point calibration
The command AZ is used as reference point for all weight calculations and will setup in mV/V. Permitted values
are ± 32 000 (= ± 3.2000 mV/V).

ZT Zero tracking
This command enables or disables the zero tracking. Parameter = 0 disables the zero tracking and
parameter = 1 enables the zero tracking. Issuing the command without any parameter returns the current
ZT value.

Zero tracking will be performed only on results less than +/-0.5 d at a rate of 0.4 d/sec, where d = display
step size (see DS command).
The zero can only be tracked to +/- 2% of maximum (see CM command).
Factory default: ZT=0
