Now, select the “Upper Output Range”. This will set the instrument’s output to 20mA. Use your
voltmeter to read the voltage drop across the 250Ω resistor and calculate the actual current
going through the resistor.
Example: A voltage reading of 4.91v equates to 19.64mA (4.91V ÷ 250Ω = 19.64mA). Enter
this value in the Measured Output Current box and then push the “Trim” button.
Now that the 2-point output trimming has been done you can test the results by entering an
output value in the “Set Current to” box. Enter 4 (for 4mA) in the box, select the “Set” button and
the instrument’s output will go to 4mA and you can check for a 1V reading across the resistor.
You can then enter 20 and check for a 5V reading across the resistor.
There is no need to press the “Apply” button as all trim changes take immediate effect.
Note:
When complete BE SURE to press the “Clear” button to return control of the output back
to your THZ
