Load Setup Option
The power supply has an internal dummy load that can be enabled to increase the speed of the
voltage fall time for high speed test applications. The effectiveness of this function is
dependent on the DUT (device under test) and may or may not be useful for some applications.
This feature should only be used with caution, as it is not designed for all applications.
DO NOT enable this function for applications such as connecting devices for battery charging
or powering electric motors. All other applications that may behave similarly to these types
of loads should NOT use this function. This function is disabled by default.
DO NOT enable this function for battery test applications (i.e. battery charging) and all
applications that may have a high charge. If a battery with a low voltage is connected to
the power supply while the output is OFF (disabled), the dummy load will drain the
battery. If the battery capacity is large and this function is enabled, a large current will
flow and damage the power supply and the dummy load.
To enable or disable this function, follow the steps below:
1. From the CONFIG menu, select Load and press .
2. Select between the two options:
Off – Disables the dummy load (default).
On – Enables the dummy load.
3. Select the desired option and press to save the change.
4. To exit the menu at any time, press twice.
External Analog Control
The power supply output can be controlled and monitored by external DC voltage sources (0 – 5
V or 0 – 10 V) or resistances (0 – 5 kΩ or 0 – 10 kΩ).
Configure Monitoring Source
Follow the steps below to configure the source to use for monitoring.
Note: Voltage monitoring is on Pin 23 and current monitoring is on Pin 24 of the DB25
Analog interface.
