The instrument is set to accept a setpoint from either an analog or a digital source. Although this setting can be changed
with parameter Control Mode , the instrument usually returns to its default control mode at every power-up or reset. The
default control mode can be set with parameter IO Status ; to change it, use the procedures as described below.
Changing from digital operation to analog operation:
1. Set parameter Init Reset to 64 (unlocked)
2. Read parameter IO Status
3. Add 64 to the read value
4. Write the new value to parameter IO Status
5. Set parameter Init Reset to 82 (locked)
Changing from analog operation to digital operation:
1. Set parameter Init Reset to 64 (unlocked)
2. Read parameter IO Status
3. Subtract 64 from the read value
4. Write the new value to parameter IO Status
5. Set parameter Init Reset to 82 (locked)
The procedures described above do not change the value of parameter Control Mode directly. To apply the new default
control mode immediately, change the value of parameter Control Mode manually or reset or restart the instrument.
