Scaling setting:
The 0% and 100% of the measurement range can be set to the desired values by setting parameters.
Note: After initialization, the parameters will return to the default values.
Input Scaling Value A
Enter the desired zero value (0%). (Input scaling value A < Input scaling value B)
Input Scaling Value B
Enter the desired full scaling value (100%).
Note: For setting input scaling value A and B, proceed with the same method. The combination of inputting parameter and Teach Calibra-
tion is unable.
For product version 1.04 or eariler;
Input Scaling Value A
"0.0" is displayed as factory default setting or after initialization. For setting desired input scaling value A, calculate by using the formula
shown below. (Input scaling value A < Input scaling value B)
(Example)
Input type: 0 to 150V
Input scaling: 50 to 150
50 + (150 x (5 / 100)) = 57.5
(Zero value) (5% value of full scale of input type 0 to 150V)
Input Scaling Value B
Enter the desired full scaling value (100%).
Decimal point position: Decimal point position is specified independently from the scaling. When you set the display scaling, include
zeros for fractions (10000 to show 10.000).
Analog output: When the forced zero or low-end cutout is ON, the analog output is proportional to the display value.
Analog output 0% / 100% adjustment: Pressing [Shift] button switches the signal to increase or decrease, and then pressing [Up] button
controls it toward the desired output value. 0% value < 100% value

Low-end cutout: Input signal below the preset cutout value is forcibly cut to 0.
Set for the three lowest digits of the scaled range (disregarding the decimal point)
With the cutout set to OFF, the low-end cutout value setting is locked.
Automatic return time to Measuring Mode: The display goes back automatically to Measuring Mode if the front buttons are left untouched
for the specified time period while it is in one of the setting modes (except the loop test output mode).
With this value set to 0, the display must always be exited manually from the setting mode.
Transition time to Lockout Setting Mode: The display goes to Lockout Setting Mode only when the designated buttons are pressed for the
specified time duration.
