Data Byte #0 Cutoff control variable:
0 - cutoff option is switched Off
1 - cutoff option is switched On
Data Byte #1 Cutoff On Value, in 1/10% of the Primary Variable Upper Range Value (say, 5% will result
in a value of 50 on a bus). When cutoff is switched Off (Data Byte #0 = 0), the instrument
still uses the cutoff option, and the defaulted On Value is returned (that is not stored in
EEPROM!). The latter might be either 0.1% or 1% depending on the PulseType value (refer
to the instrument Operating Instructions.
Data Byte #2 Cutoff Off Value, in 1/10% of the Primary Variable Upper Range Value. When cutoff is
switched Off (Data Byte #0 = 0), the instrument still uses the cutoff option, and the defaulted
Off Value is returned (that is not stored in EEPROM!). The latter might be either 0.2% or 2%
depending on the PulseType value (refer to the instrument Operating Instructions.
