Measurement Of Voltage Rise Time; Saving And Recalling Settings - ITech IT8500plus Series User Manual

3.10.6 Measurement of Voltage Rise Time

The IT8500+ series electronic load is provided with special voltage rise/drop
time measurement function. This function gives a simple analog of voltage
rise/drop speed of oscilloscope test power.
Operation methods:
Set initial Voltage and Final Voltage
1. Press [Shift] + [9] keys to enter configuration menu. Press Right key.
Select Measure and press [Enter] key.
2. Press
to set initial voltage value and press [Enter] key.
3. Press
to set final voltage value and press [Enter] key.
4. Press [ESC] to exit setting.
Start timer function
5. Press [Shift] +[8] keys to enter system menu. Press Right key till
"DISPLAY" flicks and press [Enter] key.
6. Press
key.
7. Press [ESC] to exit setting.
8. VFD second line will display time 0.0000S.
Measurement of Rise Time
9. Connect DC power to be tested to the input terminal of the electronic load.
The power is set with a value that is higher than the set final voltage value.
Keep power output in OFF status.
10. Set a constant current value on the load and open the load input.
11. Open the power output.
12. The electronic load timer starts timing. After ending, time will keep stable,
which is rise time of voltage.
13. Turn off the power output. The electronic load VFD will display voltage drop
time.

3.11 Saving and Recalling Settings

We can save some often-used parameters in the non-volatile memory,
including working mode, voltage/current value and so on. IT8500plus series
provide 100 non-volatile registers.
They are divided into 10 Memory groups: Group0-9.You can set it in the system
menu.

Group0 means you can save and recall parameters in 0-10 registers.

Group1 means you can save and recall parameters in 11-20 registers.

Group2-Group9 can be concluded in the same manner.
to select TIMEV1. Press [Enter] key. Press numeric keys
to select TIMEV2. Press [Enter] key. Press numeric keys
key to select "On". Start timer function and press [Enter]
