Output
Current Select the Set Output To 0% button or the 100% button.
The message popup at right appears.
Caution:
In Output Mode, output current is fixed at 0% or
100%. Ensure that the loop is in Manual control.
Select the Yes button, and at the meter, observe the
level of loop current.
NOTE:
On the voltmeter, 4 mA corresponds to 1 volt.
Using the MC Toolkit, adjust the loop current to the Zero
Percent level (4 mA). If the current is low, tap on the
Increment button; if it is high, tap on the Decrement
button, and observe the change on the meter.
NOTE:
If the error is large, you can accelerate the
adjustment rate by changing the Step Size to 10 or
to 100.
When the zero current level (4 mA) is achieved, select
the
Set Output To 100 % button.
NOTE:
On the voltmeter, 20 mA corresponds to 5 volts.
Use the Increment and/or Decrement buttons to adjust
the output current to 20 mA.
When the 100% current level (20 mA) is achieved, select
the
Clear Output button. (Note that the button changes
to half intensity.)
