Security Information
The instrument is designed to meet IEC 61010 safety standards and has passed safety tests
thoroughly before shipping. However, improper operation during use may cause injury or death
and damage the instrument. Before use, make sure to read and understand this manual and the
precautions specified in it. Our company does not assume any responsibility for accidents and
injuries not caused by the defects of the instrument itself.
Safety Signs
This manual contains the necessary information and warnings for safe operation of the instrument,
which are necessary to ensure that the instrument is in safe operation. Please read the following
safety precautions carefully before use.
The numbers in this manual show particularly important information, and users should
read it carefully before using the machine. on the instrument indicates that the user must
compare the corresponding topics in the manual before using the corresponding functions.

Accuracy
We use f.s. (full scale), rdg. (Reading), and dgt. (Resolution) values to define measurement
tolerances, which have the following meanings:
f.s. (maximum display value or measurement range)
Maximum display value or measurement range. This is usually the name of the currently selected
range.
rdg. (read or display value)
The currently measured value and the value displayed on the measuring instrument.
dgt. (resolution)
The smallest displayable unit of a digital tester is to make the digital display display the input
value of the smallest significant digit "1".

Temperature and humidity range to ensure accuracy:
23 ± 5 ° C, below 80% RH (non-condensing)
To avoid malfunction or damage to the instrument, do not place the tester in the following places
Places subject to direct sunlight and high temperatures
It will splash into places where liquid temperature is high and condensation occurs
Exposed to dusty places
Locations subject to corrosive or explosive gases
Places with strong electromagnetic fields and electromagnetic radiation
Places subject to frequent mechanical vibration
Pre-check
Before using the instrument for the first time, verify that it is operating normally and that it is not
damaged during storage or transportation. If you find any damage, please contact your dealer or
your representative.
Before using the instrument, make sure the test leads are well insulated and the
conductors are exposed. If a similar situation occurs, there is a danger of electric
shock when using this instrument, please contact your dealer or Jinailian
Electronic Technology Representative to replace the equipment.
Use of the instrument
To avoid electric shock, do not disassemble the instrument case. There are high
voltage and high temperature parts inside the instrument during operation.
To avoid damaging the instrument, prevent physical impact when moving and
operating the instrument. Extra care should be taken to prevent the instrument
from falling.
The power should be turned off. while stop using the instrument.
Use of the test cable
To prevent electric shock, do not short-circuit the top of the test leads and the
voltage-carrying lines.
4/25
• When performing tests, use the instrument's own test lead option for safety
reasons.
• To avoid damage to the test leads, do not bend or stretch the test leads.
• The probe at the front of the test lead is sharp. Be careful not to get scratched.
Do not hold the cable. Hold the connector.
Measurement considerations:
To avoid electric shock and short circuit, the following procedures must be
followed:
• Do not get the instrument wet or measure with wet hands. Doing so may cause
an electric shock.
• Do not modify, disassemble or repair. Failure to do so may cause fire,
accident, or personal injury.
• Do not place on an unstable stand or tilted place. Failure to do so may result in
injury or malfunction of the unit due to falling or falling over.
• To prevent damage to the instrument, avoid vibration and collision during
handling and use. Pay particular attention to collisions caused by falling.
• To avoid damage to the instrument, do not connect the measurement terminal
to the EX.SW terminal, EX.I / O terminal, or communication terminal.
Chapter 1 Overview
1.1 Introduction
JK2683B insulation resistance tester is an instrument for testing the insulation resistance of
components and equipment. Using constant voltage test method, the voltage output range is 25 ~
1000 V, and the maximum output current is 1.8mA. It also has a contact anomaly detection
function and a short circuit anomaly test function. The fastest test time is up to 50ms. As the
standard output interface of the battery short-circuit tester is an external output interface (EX.I / O),
RS-232C interface, Ethernet interface (LAN), analog output interface (ANALOG OUTPUT) and
U disk interface.
Therefore JK2683B is suitable for use in the field with different connection requirements,
including production and testing lines and laboratories.
1.2 Performance characteristics
□ Appearance
• 3.5-inch high-resolution TFT display for easy operation
• Compact and powerful body
□ Test voltage source
• Test high voltage source using switching power supply principle
• Maximum constant current 1.8mA output
• Voltage adjustment range 25 ~ 1000 V, step 1V
□ Quick test
• The minimum test cycle takes only 50ms
5/25
□ Four-end test
• The instrument can detect abnormal test leads
• The instrument can detect abnormal contact conditions of the measured object (to avoid
misjudgment of open circuit)
□ Short circuit detection
• The instrument effectively detects short-circuit conditions to avoid direct application of high
voltage to break through defective products and cause products
□ Rich interface configuration
• External I / O port
• RS-232C interface
• Ethernet interface
• Analog output interface
• U disk interface
□ Automatic discharge
• After the test, the instrument will automatically discharge
• Non-contact constant current discharge, fast, efficient and reliable
□ Power supply
• 100 ~ 240 V wide power supply
• Automatic recognition of power frequency 50Hz / 60Hz
• Maximum power consumption 15W
