0% and 100% Values
These values become references for the source values when dividing or sweeping the source
values.
When the source is to be generated in divisions, the interval between 0% and 100% is divided
equally by a specified number, and the source value is changed stepwise through key operation.
In a linear sweep, the source value is varied linearly from 0% to 100% or from 100% to 0% over a
specified time period.
In a step sweep, the interval from 0% to 100% is divided equally by a specified number, and the
source value is automatically varied stepwise.
Number of Divisions
The interval between 0% and 100% is divided equally by a specified number, and the source value
is changed stepwise by operating the cursor keys (UP and DOWN keys).
For example, if 0% is set to 50 mV, 100% is set to 100 mV, and the number division is set to 4,
each time you press UP, the source value changes as follows: 0% (50 mV), 25% (62.5 mV), 50% (75
mV), 75% (87.5 mV), 100% (100 mV).
When the source range is 1-5V, 1-5V√, 4-20mA, 4-20mA√, or 4-20mA Simulate, the number
divisions is fixed to 4.
Display Switching
You can select the value to show on the main display of the function 2 display area between a
physical value such as a voltage or a percentage.
In the case of a temperature measurement using a thermocouple or RTD, the thermal electromotive
force or resistance can be shown in sub display 2. Moreover, in the case of a temperature
measurement using a thermocouple, the reference junction temperature can also be shown.
