Test Systems
-
In-Circuit Test (ICT) tests populated circuit boards by means of electronic measurements through thin needles on test fixtures. We offer in-circuit testers for various testing strategies – from the flexible 19“ rack to the ergonomic high-performance tester. And all of our in-circuit testers are also available in the Lambda edition for true parallel testing. The flying probe test checks your printed circuit boards using four movable test heads. This requires no fixtures and allows for flexible test program generation. That makes our flying probe test systems ideal for a high mix of printed circuit boards and small to medium test volumes, such as for prototype testing.

SparkFun Current Sensor Breakout
ACS723
-
The SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for moderate AC and DC current sensing applications. The ACS723 sensor uses a Hall effect sensor to output a voltage relative to the current flowing through the IP+ and IP- pins on the board. The advantage of using a Hall effect sensor, specifically, is that the circuit being sensed and the circuit reading the sensor are electrically isolated meaning that, although your Arduino is running on 5V, the sensed circuit can be operating at higher DC or AC voltages!

AC Resonant Test System
-
Yangzhou Power Electric Co., Ltd
Testing of certain apparatus requires much high voltage or current that a straight AC test system is not sufficient. Thus resonant test reactor with a variable core is needed. The main advantage of such test systems is lower input power and larger output power. The resonant test system is designed to compensate capacitance in the testing circuit precisely by tuning inductance of the test system. AC resonant test system is used for factory testing of middle, high and ultra-high voltage cables, capacitors, generators, motors, power transformers and gas-insulated switchgears.

Digital Clamp Meter
-
A clamp meter is convenient for measuring instruments that allows the measurement of current simply by clamping a wire while being energized without cutting a circuit. In cases of measurement by a multitester and digital multimeter, the circuit must be cut to measure current. In contrast, with a clamp meter, current can be measured simply by clamping a live wire over its sheath. In addition to its simple operation, it allows safe measurement of a higher current.
