Remote high-current calibration
1. Connect the instrument with the digital multimeter (DMM), shunt, and load (electronic load or
resistor). For details, see Current calibration connections (on page C-8).
2. Perform calibration step 5 to step 8.
You must input the measured value from the DMM. The value should be within the expected range.
A message will indicate if the DMM data entry was out of the expected range. Verify that the proper
shunt value was used or that the cables are properly connected.
You can send SYST:ERR? to query any error messages and error event codes. For calibration error
messages and codes, refer to Error summary (on page 8-3).

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.
