High Voltage Test Equipment
-
A hipot test is conducted by ensuring no current flows from one point to another on a circuit. A hipot test will take two conductors that should be isolated from one another and passes a high voltage between the two points. The current which flows between these points is then measured. If too much current flows, this would indicate that the points are not well isolated and the test will fail.

Materials Evaluation and Engineering
Some problems require solutions beyond the standard test methods and procedures routinely performed at MEE. Replicating the suspected cause of failure on an exemplar part can provide valuable information about the likelihood of that failure case. Likewise, intentionally causing component failures in a variety of ways can provide insight into possible failure scenarios. Wondering how (or if) a design or part can be tested? Give us a call – the engineers and technicians at MEE enjoy the hands-on experience of designing customized testing plans for your unique challenges.

Pressure Test & Calibration Pumps
-
Pressure Test Pump is a hand operated pressure pump designed to generate pressure from 95% vacuum to 1,500psi (100bar). A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 10 Pa (0.1 mbar). A specially designed shut-off valve makes the pressure as stable as possible during calibration. A built-in gas-liquid isolator protects the pump from moisture and dirt to reduce the need for maintenance. Two hand-tight quick connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The 918 is an ideal comparison test pump for pressure instruments calibration.

Amplifier, Switch and Test Box
CLIOQC Model V
-
The QCBOX Model 5 is a non-conventional unit designed to fulfil actual and future needs of an electro-acoustical analyzer like the CLIO system. It is USB linked to a PC and can be configured, with dedicated software controls, to assist frequency response and impedance measurements or to perform DC measurements. Using it for frequency response measurements acts as 50W power amplifier to drive the speaker or network under test while routing one-of-four inputs to the analyzer as well the current sensing output. The four inputs are able to provide a phantom power supply both for Audiomatica or general purpose microphones (0-24 V range, software controlled). Impedance measurements can be done either switching the D.U.T.’s load across the analyzer’s input or using a dedicated output, ISENSE, thus allowing impedance measurements in constant voltage mode as well voice coil current distortion analysis. An internal ADC measures the DC current into the voice coil. Thanks to an internal software controlled voltage generator the speaker can be driven with a superimposed DC voltage (±20V), allowing for measurements of large signal parameters. Two ADC converters with a ±2.5 V and ±5 V are available at inputs 3 and 4 to measure the displacement with a laser sensor or any other DC signal. A dedicated digital input handles an external foot pedal switch (or TTL signal) to be connected and triggers QC operations. A 6 bit output – 5 bit input TTL digital port is available to interface the QCBOX and driving software with external hardware (like turntables for example).The QCBOX Model 5 finds use both in laboratory for R&D applications and in production lines setups.
