b. Verify that the loop is in manual control. In output mode, output current is fixed at
the 0% or 100% level as selected in the TRIM DAC CURRENT box in the previous
step.
c. Select Yes, and observe the loop current level. A meter reading of 4 mA corresponds
to 1 volt as measured across the precision 250 ohm loop resistor.
d. Use the Toolkit to adjust the loop current to the Zero Percent level (4mA). If the
current is low, tap the Increment button; if the current is high, tap the Decrement
button. Note that the value on the meter changes accordingly. If the error is large,
accelerate the adjustment rate by changing the Step Size to 10 or 100.
e. After establishing the zero current level (4 mA), select Set Output To 100%. A
meter reading of 20 mA corresponds to 5 volts as measured across the precision 250
ohm resistor.
f. Use the Increment or Decrement button, as necessary to adjust the output current to
20 mA. When the current reaches the 20 mA level, select Clear Output; the button
will change to half-intensity.
4. Change the display in output mode as follows:
a. Selecting the Back button before selecting the Clear Output button, you will be
prompted to confirm that you want to clear the output.
b. If you want to stay in output mode while viewing other displays, select Yes;
otherwise, select No and the Clear Output button.
