2. Overview
In this chapter you will learn:
● Introduction
● Main specifications
● Main functions
2.1 Introduction
Thank you for purchasing the JK625 Handheld DC Low Resistance Tester.
JK625 battery internal resistance tester is an instrument that can measure battery internal resistance
and voltage online. It is controlled by a high-performance 32-bit ARM microprocessor. It is a
miniature handheld instrument with automatic real-time detection and a built-in large-capacity
lithium battery to achieve long standby JK625 has the superior performance of both portable and
desktop instruments. The main performance is compatible with Nissho 3554. The instrument can test
0.01mΩ ~ 3.3Ω resistance and 0 ~ 60V DC voltage. The data display is stable. The maximum
resistance is 3300 display digits. Voltage Maximum 6000 display digits.
The resistance measurement of the instrument uses the vector test principle, and the voltage
measurement uses the differential test principle, so the open circuit voltage can be accurately
measured. In addition, the instrument has a professional sorting function, a built-in sorting record,
and GD / NG sorting results show the sorting sound setting, which is applied to the UPS online
battery measurement automatic sorting system to complete a fully automatic assembly line test.
JK625 is equipped with 500 sets of data storage, which can save measurement data with one click,
saving you the time of recording data. And can be equipped with a USB interface for remote control
and data acquisition and analysis, making him very suitable for all kinds of battery assembly line
inspection.
2.2 Main specifications
JK625 hand-held series of technical specifications, including the basic technical indicators of the
instrument and the range allowed by the instrument test. These specifications are achievable at the
factory.
● Basic accuracy: resistance: 0.5%, voltage: 0.05%
● Enter. Frequency: 1kHz
● Maximum display digits: resistance: 3300, voltage 60000
● Range automatic, manual or nominal test-Provides a test range of 0.001mΩ to 3.3Ω.
● Test speed: 1 time / second
● Four-terminal test
● Provide high current and low current test modes-different test modes can be suitable for test
pieces with different properties.
● Display-With 5.6 "inch true color LCD, the measured value and sorting result (GD / NG)
are displayed at the same time.
2.3 Main functions
2.3.1 Calibration function
Full-scale short-circuit clear function.
2.3.2 Comparator function (sorting function)

8/24
Built-in sorting data for GD / NG judgment of the DUT.
●Comparison method:
Absolute tolerance ± TOL sorting: The absolute deviation between the measured value and the
nominal value is compared with the limits of each file.
Percent Tolerance TOL Sorting: The percentage deviation between the measured value and the
nominal value is compared with the limits of each range.
Sequential comparison sorting: the measured value is directly compared with the upper and lower
limits
●Sound setting:
Users can set OFF / GD / NG sound according to their needs.

3.3 Use of external power
The instrument comes standard with a power adapter.
In addition to supplying power to the instrument, this power supply also charges the lithium battery
inside the instrument, so the power adapter cannot be replaced. It is recommended to use our
company's special power supply.
Figure 3-2 Connecting the external power adapter to the instrument.
Plug the power adapter into the AC adapter input jack on the instrument.
3.3.1 Battery charging function
If the battery is not fully charged, the instrument's charging circuit will automatically start to charge
the internal lithium battery after the power adapter is plugged in. The instrument's built-in indicator
of the power switch key will light up to indicate that charging is in progress. This indicator will
remain lit even after the instrument is turned off, until it goes out when the battery is fully charged.

10/24
3.4 boot
The keys are light touch keys. Press the power key to turn the instrument on or off.
3.5 Test connection
The instrument uses four-terminal tests to improve accuracy.
Before testing, please insert the test lead of the instrument into the instrument jack.
Figure 3-4 Connect the test terminal.
Warning: Do not apply DC voltage or current to the test terminal, otherwise it will damage the
instrument.
Warning: When testing a charged device, make sure that its charge is discharged before measuring.
3.5.1 Test fixtures and cables
According to our company's long-term investigation of users, user-made or other company's test
fixtures or test cables may cause incorrect measurement results. We recommend that you use our test
fixtures or test cables.
The contact springs of our test fixtures are silver-plated or gold-plated, which will cause abrasion of
the electroplated surface during long-term work (such as 1 ~ 2 years). It is recommended that you
replace the new fixtures in time if you find that there are obvious deviations in several tests.
