4.3.2 4-20 mA Function
The source current can be increased or decreased in 4 mA steps.
4 mA
steps
1
Connect the terminals.
2
Use the FUNCTION key on the SOURCE side to align
the
source mark with DCA. (DC current selection)
3
Use the RANGE key to select the 4-20 mA range. (4-20 mA lights.)
4
Set the output value.
Use the ▲ ▼ output value setting keys for the two leftmost digits to set
the value in 4 mA steps up and down. (4-8-12-16-20 mA)
Use the ▲ ▼ output value setting keys for the three rightmost digits to
increment or decrement the value by one count.
(Use these keys to make fine adjustments, etc.)
Press the CLEAR key to restore the setting to its initial value (4.000).
5
Press the SOURCE ON/OFF key to start generation.
(SOURCE OFF changes to ON.)
6
Press the SOURCE ON/OFF key again to turn off the output.
(OFF lights and the output terminals are open-circuited.)
Tip
A step-down operation in which the setting value becomes 3 mA or less is not
possible.
• When you use the linear sweep function,
the generation start (0%) is set to 4 mA. Refer to "4.9.2 Linear Function."
• The same is the case when you use the divided output (n/m) function.
Refer to "4-8 Divided Output (n/m) Function."
