BT601 is a versatile Cable scan (diagnostic) & Wire Finder (tracing) tool, designed for cable/network system installation and network technician to diagnostic network problem.
Wire finding is BT601 major unique function where other cable checkers do not have, it can locate up to 3000m long wire/cable even in a complex PC network or telephone system.
BT601 also built-in LAN cable mapping function, to quickly diagnostic LAN cable condition and identify fault point.
Bright white LED torch and External Earphone support is BT601's value added function to enable service technician to work conveniently and comfortably in dark and noisy environment.

QNImits is an innovative hand held test instrument, which uses the industry’s proven V-I Trace technique of learn and compare of Nodal impedances. Using this technique the technician only requires a known good board for comparison with a faulty one without schematics and functional details of PCBs. The known good board’s VI traces can be learnt and stored for future reference as well.
QNImits uses probe – reference to either on-line comparison of each node or alternatively uses external MUX switch and clips / adopters for multi-pin learn and compare.
QNImits displays the test results as VI trace, which shows the current against applied voltage in most commonly used graphical view. These trace formats help the user to easily understand the nodal behavior and interpret the results for quick diagnostics.
Using V-I curve traces one can detect a change in devices’ pin characteristics due to aging or damage caused by external forces. QSM VI mode uses all pins of the device as reference and hence able to detect leakages between pins as well.
This test technique works most of the time, because most of the failing devices shows a different response to VI trace unless there is no terminal failure.
The USB interface which comes as standard with QNImits helps in connecting to PC/AT or Laptop so that signature information learnt from Known Good Board can be saved for further verification and analysis.

‘AG’ Series sensors from NK Technologies protect people, products and processes from ground faults by monitoring all current-carrying wires in grounded single or 3-phase systems.
Operating Principle: Under normal conditions, the current in the hot leg of a two-wire load is equal in strength but opposite in sign to the current in the neutral leg. These two currents create magnetic fields that are also equal but opposite. When conditions are normal, the fields cancel, producing a "Zero Sum Current". If any current leaks to ground from one wire (Ground Fault), the two currents become imbalanced and the result is a net magnetic flux or field. AG Series ground fault sensors monitor this field and alarm when leakage rises above setpoint. This concept applies to grounded 3-phase delta and wye systems.
