Step 3. Wait 5 minutes for the temperature to settle. Select the first current calibration point.
Front Panel Menu Reference
Wait 5 minutes, then select Next again.
Step 4. Connect a precision shunt resistor to the output. The shunt resistor should be able to measure
at least 70% of the output's full-scale current (see
across the shunt resistor.
Front Panel Menu Reference
Check that the shunt is connected and select Next.
Step 5. Select the second current calibration point. Wait 5 minutes for the temperature to settle.
Calculate the shunt current (I=V/R) and enter the data.
Front Panel Menu Reference
Display shows: "Enter P2 measured data". Enter the data
from the external DMM. This should be about 70% of the
full-scale current rating. Press Enter when done. Press Back
to finish.
Enter a Calibration Date
Front Panel Menu Reference
Select System\Admin\Cal\Date.
Enter the calibration date in the Date field. If desired, you
can enter alphanumeric data in this field.
