Security needs
warning DANGER ：When you find the following abnormal conditions, please
terminate the operation immediately and disconnect the power cord. Contact and repair
the Jinke instrument sales department immediately. Otherwise, it will cause a fire or
potential danger to the operator.。
Abnormal operation of instrument
Abnormal noise, odor, smoke or Flash occurred during operation.
During operation, the instrument produces high temperature or electric
shock.
The power cord, power switch or power socket is damaged.
Impurities or liquids flow into the instrument.
security information
warning danger：To avoid possible electrical shock and personal safety, follow
these guidelines.
Disclaimer: Users should read the following safety information carefully before starting to
use the instrument. The company will not be liable for any personal and property losses
caused by non-compliance with the following provisions.
Instrument grounding: to prevent the danger of electric shock, please connect the power
ground.
Do not use the instrument in an explosive gas environment: Do not use the instrument in
an inflammable and explosive gas, steam or dust environment. The use of any electronic
device in such an environment is an adventure for personal safety.

Introduction
major function
2.1 introduction
Thank you for purchasing JK2520B /JK2520C AC resistance tester.
JK2520B/JK2520C is a fully automatic real-time detection of miniature desktop
instruments controlled by high-performance 32 bit ARM microprocessor.The instrument
can test the resistance of 0.001mΩ~33kΩ ，the DC voltage of 0.00001V~120.000V，the
maximum resistance of 33000 display digits ，and the maximum voltage of 600 000
display digits.JK2520B/JK2520C has the characteristics of high precision, high resolution
and ultra-high speed measurement. It provides 0.2% resistance accuracy and 0.01%
voltage accuracy. The maximum measurement speed can reach 145 times per second.
The instrument is used for professional sorting function, standard Handler (PLC) interface,
output resistance HIGH / IN / LOW signal and voltage HIGH / IN / LOW signal separately.
It can completely cope with high-speed automatic sorting system to complete automatic
pipeline test, and the enhanced IO signal can directly drive power relay and signal relay.
The instrument has built-in RS-232C interface, optional USB232 interface and RS485
interface, universal data acquisition software, database function and Excel export function.
It can be effectively used in remote control and data acquisition and analysis.
The instrument uses Jinko instruments to enhance the computer remote control
instruction set, compatible with SCPI (Standard Command for Programmable Instrument
Standard Command Set), and efficiently completes remote control and data acquisition
functions.
The newly designed AC resistance testing principle can be used for almost all battery
internal resistance testing, including lithium battery, lead-acid battery, button battery and
other battery pipeline inspection. JK2520B do not support UPS online measurement,
JK2520C support UPS online measurement.
