• 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.
