UT3550 is all automated and real-time detection handheld instrument which made by high-performance 32 bit ARM microprocessor.
This instrument can test resistance 0.001mΩ~30.00Ω and DC voltage 0.0001V~100.00V.
It has built-in USB-Type-C interface, through data collection software to remote control, collect and analyze data.
UT3550 use remote control instruction set and compatible with SCPI (Standard Command for Programmable Instrument) to fulfill remote control and data collection.
The AC resistance testing principle can be used for the internal resistance testing of almost all batteries,including lithium batteries, Hydrogen fuel batteries, lead-acid batteries, button batteries and other batteries.
The design allows direct on-line measurement of the UPS without loss of accuracy and stability.
IP65 dustproof and waterproof, even in the dust pollution, splashing industrial site, can also help you to accurately measure.
Main Function
Calibration Function
Full-range short circuit zeroed function.
Comparator Function（sorting）
Built-in sorting data, estimate measured object by OK/NG.
Compare Method:
ABS tolerance ± TOL sorting：compared with the upper/lower value of measured value and absolute deviation value
PER tolerance
TOL sorting%TOL sorting：compared with the upper/lower value of measured value and percentage deviation of nominal value
SEQ comparison sorting：measured value compared with the upper/lower value
