Front Panel Controls; Remote Programming; Operating Modes; Constant Current(Cc)Mode - ITech IT8518B User Manual

GENERAL INFORMATION
F r o n t P ane l Co n tr ol s
The front panel has keyboard controls for setting the input voltage, current and resistance.
The panel display provides digital readouts of a number of functions including the inputs.
Annunciators displaythe operating status of the electronic load.
Rem ote P r o gra m m in g
The electronic load may be remotely programmed from the computer via the IT-E131 isolated
communication cable.
O p erat i ng M o d es
The four modes of operation are:
1: Constant current (CC)
2: Constant voltage (CV)
3: Constant resistance (CR)
4: Constant power (CW)
Con stan t C u rre nt ( CC )M o d e
In this mode, the electronic load will sink a current in accordance with the programmed value
regardless of the input voltage. CC mode can be set with front panel keys. The CC mode
parameters are discussed in the following paragraphs.
Con stan t R e si st a nc e ( CR) Mode
In this mode, the module will sink a current linearly proportional to the input voltage in
accordance with the programmed resistance. The CR mode can be set at the front panel.
The CR mode parameters are described in the following paragraph.
