Display shows: "Enter P2 measured data". Enter the data
from the external DMM. Press Enter when done. Press

Current Temperature Coefficient Calibration
The temperature coefficient calibration procedure must be performed Before any
other current calibration procedures.
Step 1. Connect a precision shunt resistor to the output. The shunt resistor should be able to measure
the output's full-scale current (see
resistor.
Step 2. Select the temperature coefficient calibration.
Front Panel Menu Reference
Select System\Admin\Cal\Misc\CurrTC.
Check that the shunt is connected and select Next.
Step 3.Select the first 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 P1 measured data". This should be
about 50% of the full-scale current rating. Press Enter when
done.
Step 4. 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 80% of the full-scale
current rating. Press Enter when done.
Step 5. Select the third 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 P3 measured data". Enter the data
from the external DMM. This should be about 100% of the
full-scale current rating. Press Enter when done. Press
Back to finish.
