Math Menu Function (Math) - ITech IT6412 User Manual

Configuring Current Sense
This option is used for configuring current sense: High and Auto. When Auto is
configured, switch to Low mode when current is lower than 5mA. The
measurement precision is 0.05%+2Ua and resolution ratio 0.1uA.
Configuring Output-off State
This item is used to set the status after the power output is turned off. Select
Menu > Config > Conf2 to enter configuration menu interface. Press up or down
keys to select Output-off, and then press [High Impedance], [Normal], [Zero] or
[Relay off] soft keys on the right side to set the output off status.

Select "Menu > Math" to enter the Math Menu interface. The menu is described
as follows:

Select High Impedance. After the power output is turned off, the output
terminals of the power supply can be seen as a DC impedance (100k to
400k). The impedance values of different models are different.
Select Normal. After the power output is turned off, if the output voltage is
0V, the output current is 0.05% of the output rated value.
Select Zero. After the power output is turned off, if the output voltage is 0V,
the current setting value keeps the value when the output was turned on.
Select Relay off. After the power output is turned off, use the relay to
disconnect the internal circuit and external load. The isolation impedance is
over 1 GΩ.
