BK Precision 8500B Series User Manual

Operation Modes 33
6.1 Static Modes
The electronic load provides ve static load modes. They are constant current (CC) mode, constant
voltage (CV) mode, constant resistance (CR) mode, constant power (CW) mode, and short mode.
To select a Mode press the corresponding function key as shown in section 5.1.1. For short mode the
+ combination must be used.
When programmed to a mode, the electronic load remains in that mode until another mode is selected.
If the selected mode is in operation, selecting another mode will automatically
disable the input.
6.1.1 Range Conguration
The range for all static modes can be congured under the Setup menu. To enter the setup menu press
the + buttons.
The range can be congured to any valid value in the instrument’s full range.
Limiting the instrument’s range can improve the reading resolution if the set range
fall in the instrument’s low range. Table 6.1 list the threshold for low and high
range for all operation modes and models in the 8500B series.

(2) The slew rate specifications are not warranted but are descriptions of typical performance. The actual transition time is defined as the time for the input to change from 10% to
90%, or vice versa, of the programmed current values. In case of very large load changes, e.g. from no load to full load, the actual transition time will be larger than the
expected time. The load will automatically adjust the slew rate to fit within the range (high or low) that is closest to the programmed value.
