SLM-Series AC/DC Electronic Load Operation

3.3.3 CR Mode
Two levels can be set to allow for quick switching between two current levels. One
crest factor setting (see section 3-2) applies to both levels. Although the levels are
referenced “high” and “low,” the setting level does not require one to be higher than
the other.
In CR mode, the value setting is inverse to the increment/decrement arrows; i.e., the
↑ keys decrease the resistance setting, and the ↓ keys increase the resistance
setting.
1. Press the MODE button, until the CR LED is lit (3).
2. Press the PRES button (7) to view the programmed values.
