The instrument is set to accept a setpoint from either an analog or a digital source. Although this setting can be changed
with parameter
, 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.
