8. SETTING INPUT-RELATED PARAMETERS
8.1 Input Scaling
The MVHK allows you to set any input scaling value (displayed value) with respect to the
measured input range.
For example, if the MVHK measured input range is 4 to 20 mA DC, setting the input scaling range
(displayed value) to -50 to 150 causes the MVHK to display “0” in the PV display at 8 mA input
(equivalent to 25% of 4 to 20 mA input) as shown in the figure below.

Minimum value of measured

At 8 mA input, "0" is displayed on
the PV display.

Range code No.: 97; maximum measured input value: 20.00; and minimum measured input value: 4.00
8.3 Setting Input-Related Parameters
This section describes an example of setting the range code No. (IN) to “97,” measured
input range (RL, RH) to “4 to 20 mA DC,” the decimal point position of input scaling value (SDP) to
“0” (with no decimal place) and input scaling values (SL, SH) to “-50 to 150.”
CAUTION
Note that setting the range code No. (IN) to a value other than those specified in Section
8.2 is invalid.
