Once the calibration resistance value is set as described earlier, the general
procedure for each channel current output adjustment is:
1. Make the connections shown in Figure D-5 or D-6.
2. Send the CAL
response until a 1 is returned (typically the first query response).
3. Read the voltage output on the DMM.
4. Send the DMM value read with the
query.
5. Enter the query response.
6. Repeat steps 3, 4, and 5 until the
returns a 0.
7. Repeat steps 1 through 6 for each channel.
The first query,

mode and returns a 1 when the channel is ready for calibration. When a 1 is
returned, the channel output voltage is set to the first adjustment point.
Read the output voltage on the DMM and return the value obtained using
the n

indicating the calibration state of the channel. A value other than 0 or 2
from this query indicates additional values are needed.
