Ranges
When working in CV mode, you can press the Setup key to enter the RANGE menu. Two
overlapping ranges can be selected: LOW RANGE or HIGH RANGE. Voltage can be edited in either
of the two ranges. Low range will supply higher accuracy and better resolution when you set lower
current. 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 VOLT:RANG
command to switch voltage range.
Amax/Amin Limits
These parameters refer to the current 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
.
Voltage Level
Set the voltage level on front panel or by sending SCPI command VOLT <n>. If the load is in CV
mode, the new setting immediately changes the input. If the electronic load is not in CV mode, the
set voltage level will be saved in the instrument for use until the mode is switched to CV mode.
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.
Constant Resistance (CR) Mode
In this mode, the electronic load is equivalent to a constant resistance, as shown below. The
electronic load will linearly change the current, according to the input voltage.
