Appendix C: Calibration and adjustment Series 2280 Precision DC Power Supply Reference Manual
C-14 077085503 / March 2019
For Model 2280S-60-3, the expected values are shown in the following table.
The Series 2280 has 200 W of constant output power. Make sure that cables, shunts, and
loads are properly rated for the intended current. Incorrect shunt connections, such as using
the 5.05 Ω shunt during step 5 and step 6, can cause damage.
Step 5
1. Before starting this calibration step, configure the shunt and load (electronic load or resistor load)
as shown in the following table.
2. Enter the external shunt value and press the ENTER key.
3. Enter the measured result from the digital multimeter (DMM) and press the ENTER key.
4. After entering the data, the waiting window is displayed. You need to wait a few seconds for the
internal measurements and calculations. The step 6 calibration window is displayed.
Step 6
1. Before starting this calibration step, configure the shunt and load (electronic load or resistor load)
as shown in the following table.
2. Wait for the instrument to take internal measurements and calculations.
