Constant Resistance (CR) Mode
In CR mode, the load is regarded as a constant resistance, and changes the current
linearly proportional to the input voltage, as shown in Figure 2-8.
Figure 2-8 Constant Resistance (CR) Mode
Operation Procedures:
1. Connect the DUT and the channel input terminals of the load
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.
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. A misconnection with the terminals may cause damage to
the instrument or the DUT.
2. Power on the instrument
After the instrument is connected to the power source, press the Power key
on the front panel to power on the instrument.
3. Set channel parameters
Press CR to enter the main interface of CR mode, as shown in Figure 2-9
. At the
top of the main interface, "CR" and "STATIC" are active. Of which, "STATIC" is
highlighted.
