Operations 35
Transient Voltage Level
A/B transient voltage level can be set on front panel or by remote operation. The electronic load can continuously toggle
between the two levels when transient operation is turned on.
4.1.3 Constant Resistance (CR) Mode
In CR mode, the electronic load is equivalent to a constant resistance, as shown in figure 4.4 .
The electronic load will linearly change the current, according to the input voltage.
Figure 4.4 Constant Resistance Mode
CR Ranges
When working in CR mode, you can Press the the key to enter the RANGE menu. Two overlapping ranges can be
selected: LOW RANGE or HIGH RANGE. Resistance can be edited in either of the two ranges.
Low range will supply higher accuracy and better resolution when you set lower resistance. If any value you set is outside
the maximum value of the LOW RANGE, you should select HIGH RANGE. If the electronic load is in remote control
mode, you can use the RES:RANG command to switch resistance range.
CR Vmax/Vmin Limits
These parameters refer to the voltage high and low limit for the automatic test mode. During automatic test mode, the
device under test (DUT) must be operating within the configured values for the test to PASS upon completion. If the
DUT operates outside the configured values, the test will FAIL upon completion.
Note:
These parameters are used for Automatic Test ONLY .
Immediate Resistance Level
Set the resistance level via front panel or by sending SCPI command RES n . If the load is in CR mode, the new resistance
level setting immediately changes the input. If the load is not in CR mode, the resistance level setting will be saved for
use until mode is switched to CR mode.
