Obtaining current output signal
Use the CUR. and GND terminals of the
F331 for connection with an external
device (500
Ω or less load resistance).
Setting of D/A zero and gain
With the D/A converter of the F331, an analog
output is obtained by setting the indicated value
to output 4mA (D/A zero scale) and the
indicated value to output 20mA (D/A full
scale). Respective set values are inputted by the
D/A zero and full scale setting functions.
Example of setting
In the case where:
D/A output mode...................... 0 (linked with indicated value)
D/A zero scale .......................... 0500
D/A full scale ........................... 2500
CAUTION
- The D/A converter current output is an option.
- Do not apply external currents. Breakage will result.
Also, connecting a capacity load may cause oscillation.
