Measuring range adjustment
Introduction
The measuring range adjustment is available for current and voltage measuring ranges. Live
zero measuring ranges are not supported.
Function
The measuring range adjustment is an adjustment of the measuring range at the sensor.
It allows you to increase the resolution for a configurable part of the measuring range in S7
format.
● You activate the function in STEP 7 (TIA Portal) via the "Measuring range adjustment"
parameter.
● The "Measuring range adjustment high limit" parameter sets the high limit of the
measuring range in mV or μA.
● The "Measuring range adjustment low limit" parameter sets the low limit of the measuring
range in mV or μA.
Note
• The "Measuring range adjustment" function can be used in combination with the
"Measured value scaling" function, see also Scaling of measured values (Page 17).
• When the "Measuring range adjustment high limit" and "Measuring range adjustment low
limit" parameters are too close together, resolution may be lost, which means it may no
longer be possible to show every value.
Rules
● The limits of the measuring range adjustment must be selected within the nominal range
of the base measuring range. They are specified in integers.
● The measuring range adjustment is resolved depending on the base measuring range
from 0
● Underranges/overranges apply in accordance with the S7 format and the base measuring
range.
