Note: There is a linear constraint relationship of internal resistance between the voltage level and
the current level. (For example, the current level corresponding to 30Ω internal resistance is
166.7μA ~ 66.67mA, and the current level corresponding to 100Ω internal resistance is 50μA ~
100mA).
The signal source output impedance can be selected as 30 Ω or 100 Ω. When the test function is
selected as DCR.
Level voltage and resolution:
Note: The set test current is the output current value when the tested terminal is short-circuited. The
set test voltage is the output voltage value when the test terminal is open.
The automatic level control function can realize constant voltage or current measurement. The
automatic level control function (automatic level domain) can be set to ON on the <Meas Setup>
page. When the automatic level control function is turned on, a "*" sign will be displayed after the
current level value.
Operation steps for setting test level:
Touch and click the AC level corresponding area, the menu area displays the switching function of
the level type and adding smaller functions, you can modify and adjust according to the menu
prompts, or you can directly enter the number keys to modify the value.
Note: When you need to switch the test level between current and voltage, you must use the menu
area.
