5.3. Parameter Types and Protect Levels
The A7000 series parameters are classified into the following groups
depending on the main objective:
Condition data: A group of parameters that set basic actions such
as sampling rate and operation type of each control
Scaling data: A group of parameters relating to measurements
such as a measurement range and scaling
Comparator data: A group of parameters relating to comparison
output such as the comparison output operation
type or judgment values
Shift data: A group of parameters relating to the function that
forcibly shifts an indicated value
Linearize data: A group of parameters relating to the function that
corrects the linearity of an input value and indicated
value
Each parameter has a protect level that has been set up. Setting the
protect level of condition data allows the settable protect level of
parameters to be limited. (For the settable protect level of each
parameter, see P.L for the list of parameters in 5.1.)
For the protect levels, the higher the level value, the more the number
of parameters whose setting is disabled increases. If the protect level
is set to LV3, which is the highest level, all parameters are disabled
from being set with the exception of protect level change.
* At factory shipment, the protect level is set to LV1. (In this case, only
settings relating to display color, scaling, or judgment values can be
made).

For the voltage measurement's 15 ranges, the full-scale input value becomes "9999" when an input is 700 V.
For the large-current measurement's 26 ranges, the full-scale input value becomes "9999" when an input is 5 A.
Sets the high limit of the displayable range. (A value exceeding the digital limiter HI setpoint is not updated and is held at the set value.)
Selects the analog output's output range. * Only when analog output is provided
Sets the relationship between display and analog output. * Only when analog output is provided
Sets the decimal-point display position.
Main Setting Target and Precautions
Sets the low limit of the displayable range. (A value lower than the digital limiter LO setpoint is not updated and is held at the set value.)
