Constant Resistance (CR) Mode
In CR mode, the electronic load is regard as a constant resistance and will give
linear change of current with respect to input voltage changes, as shown in
Figure 2-8.

Operating Steps
1. Turn off the instrument, as shown in Figure 2-2, connect the DUT
and the channel input terminals on the front panel of the load.
CAUTION
While making a connection, the positive polarity of the load should
be connected to the (+) terminal of the channel output, and the
negative polarity of the load to the (-) terminal of the channel
output. Incorrect polarity may cause damage to the instrument or
the DUT.
2. Press CR to enter the main interface of CR mode, as shown in
Figure 2-9.
