Instructions

3.2.1. Model number and sink ranges
The model number along with maximum voltage, current and power values are
Detailed in this position at the top of the load front panel.
It indicates the model number and specifications of 34210A electronic loads.
3.2.2.
The user can adjust upper and lower limits for voltage, current and power within the
CONFIG menu and turn the NG Indicator ON.
Wattmeter measurement is outside these set limits then the NG indicator will
illuminate.
MODE
3.2.3.
There are four operating modes that can be selected by pressing the "MODE" key
on the 34000A series Electronic Load module.
The sequence is Constant Current (CC), Constant Resistance (CR), Constant
Voltage (CV), and Constant Power (CP). Each time the "MODE" key is pressed the
operating mode is changed. The actual operating mode selected is indicated on the
left hand side of the LCD.
The operating theorem of CC, CR, CV and CP modes are described in Section 1-1.
Common application examples for the different operating modes are described in
Section 5-3 to 5-6 respectively.
Remote
3.2.4.
If the REMOTE LCD Indicator is illuminated this means that the unit is operating
remotely via one of the optional interfaces. While REMOTE is lit it is not possible to
make settings manually at the front panel. The LOCAL button on the mainframe can
be used to revert back to front panel control. When the unit is operating from the
front panel the REMOTE LCD will not be illuminated.
3.2.5. Left 5 digit LCD display
The 5 digit LCD display is a multi-function display. The function of the display
changes depending whether the user is in NORMAL mode or in a SHORT, OPP or
OCP test modes:
Normal mode:
The left 5 digit display displays the voltage present at the load's input terminals.
The value displayed will include the automatic voltage compensation if the sense
Terminals are also connected to the device under test (DUT).
