4.5.3 CR Mode

CR Mode includes constant resistance low range (CRL), constant resistance medium range (CRM), and constant resistance high range

(CRH).

Example 1: Set the load to CRL and set the resistance value to 1.5 Ω in CV mode.

Turn on the load, and check the present power value. The operating procedures are shown below:

For the above operating procedures, the corresponding SCPI commands should be:

Example 2: Set the resistance value to 1.8 Ω in CRL.

Turn on the load, and there are two ways to set the resistance value.

Option 1:

Option 2:

For the above operating procedures, the corresponding SCPI commands should be:

Note

CRH /CRM/CRL will be shown respectively in the lower right corner of the display when the load is in CRH status, CRM status

or CCL status.
