Set The Internal Resistance; Cr Function In Sink Mode - ITech IT6000B Series User Manual

4.4.2 Set the Internal Resistance

The IT6000B series power system provides internal resistance setting (CV pri-
ority mode only). The procedures are shown as below.
1. Press the composite keys [Shift]+[V-set] (Config) on the front panel to enter
2. Press the up/down key or rotate the knob to select Output Res and press
3. Set the internal resistance value and press [Enter] to confirm.

4.4.3 CR Function in Sink Mode

This series of instruments supports CR testing in sink mode, and the sink cur-
rent capability of CR is controlled by the Is setting value in CC priority mode.
The usage of this function is as follows:
1. Press the composite keys [Shift]+[V-set] (Config) on the front panel to enter
2. Select Mode and press [Enter].
3. Select CC and press [Enter].
4. Select High or Low, and press [Enter].
5. Press the down arrow key to set the current rise and fall time.
6. Press the down arrow key to select Sink Res and press [Enter].
7. Select On and press [Enter].
8. Set the Sink Res value and press [Enter].
9. Set the voltage and current.
the configuration menu.
[Enter] to confirm.
the configuration menu.
Enter the setting interface of the loop response speed.
At this point, return to the Config menu settings interface.
Setting range: 0~7500Ω. If set to 0, the function is equivalent to that
Sink Res is selected as OFF.
The following takes the setting of 10Ω as an example to introduce the actual
test results.
a. Press the [I-set] key on the front panel to set the output current value Is.
Take –5A as an example.
b. Press the [V-set] key on the front panel to set the voltage upper limit Vh=
20V, and press [V-set] again to set the voltage lower limit Vl=0V.
c. Set the DUT (power supply) to output 80V, 10A.
