- The default values of the alarm HI limit and the LO limit are set as invalid.
Re-set the values before use.
- Since the alarm HI limit and LO limit are independent, they can be separately
used.
Key points
Turning ON/OFF near zero influences HI/LO limit comparison and automatic
printing. Refer to P.47 “6-3.HI/LO limit comparison mode” and P.63 “8-1.Auto-
matic printing command” for details.
