KEY FEATURES
FEATURES
Flexible switching between single and scan modes
One-touch switching in the setup menu, flexible application of front-end single mode testing or rear-panel multi-channel scanning
Multi-channel measurement
30-channel high-speed scanning measurement. Synchronized display.
Measurement results can be sorted in three levels.
Multiple test modes (Single mode)
Five test modes are available: R, R-T, T, LPR, and LPR-T. LPR is a low-voltage test mode designed to effectively protect the DUT
Logging (Multi-channel)
Logging: : Supports recording data up to 10,000 groups of data.
Temperature correction and conversion
Temperature correction: Compensates for measurement deviations caused by temperature fluctuations.
Temperature conversion: Calculates the difference between the DUT’s internal temperature and the ambient temperature using the thermal characteristics of the resistor.
