Remote sense terminals ensure accurate voltage measurement. Current monitoring outputs a voltage proportional to input current. External programming input allows control of CC mode via a 0-10V signal.
Factory reset restores default settings but retains EEPROM data. External programming is limited to CC and CV modes.
N6200 supports static operation modes including constant current, voltage, resistance, and power. Range selection ensures measurement accuracy.
Two methods are provided to set parameters like I-Set, Rise Slew, and Fall Slew under Constant Current mode.
To enter CV mode, users can press the CV button or navigate through the menu, with two voltage range options ensuring measurement accuracy.
CR mode can be accessed via the CR button or menu, with range selection available.
CP mode is accessible via the CP button or menu navigation, with power and slew settings adjusted similarly to other modes.
The dynamic function tests the dynamic characteristics of the DUT with modes like CCD, CVD, and CRD, including continuous, pulse, and toggle options.
The auto test feature allows users to edit sequences to simulate various load input changes.
The N6200 series supports capacity tests for batteries and capacitors, involving setting parameters like I-Discharge and V-End.
The ESR test evaluates battery and capacitor ESR using a constant current discharge method.
Includes setting discharge current, ESR test steps, OCP test procedures, and MPPT test steps.
Regular maintenance includes cleaning and fault self-inspection, with annual calibration recommended.
Includes measurement accuracy conditions, model specifications, and operating environment details.
Details voltage and current ranges, power and resistance modes, and interface and input requirements.
