QA350
-
The QA350 relies on a built-in reference to calibrate the ratio between the hi and low ranges. If you have a preferred lab reference, you may use that it to improve the QA350 accuracy beyond the indicated +/- 400 PPM. For example, various vendors on eBay can provide calibrated +/-30 PPM 5 or 10V voltage references that can be used to set the ultimate accuracy of the QA350 to under 50 PPM at room temperature.

Analog Tank Test Kit
4108
-
The voltmeter included in the kit, the “Model IA” voltmeter, is designed for ease of use by meter readers and corrosion technicians alike and the voltmeter comes with an integrated RE-5 reference electrode attached for “metallic structure-to-soil” potential difference readings. The kit also includes a special test lead that has a brass thumb screw on one end which allows the test lead to substitute for the RE-5 reference electrode. This substitution allows the voltmeter to take “structure-to-structure” potential difference readings. The voltmeter offers a 0 - 2VDC range with a 10MΩ input impedance and the analog display presents a color divided scale for convenient indication as to whether or not a carbon-steel structure is receiving a suitable level of cathodic protection, with respect to the accepted 0.85V (850mV) threshold value.

Platforms
-
The use of switching systems to route instrumentation and stimulus signals to appropriate test points on a unit under test has a very crucial role to play in most electronics test systems. The sharing of test resources, connection of calibration references, load management, and many other functions are all managed by the switching system, the switching system acts as the interface between the unit under test (UUT) and the test equipment.

Dielectric Loss Tangent Testing Instruments
-
Insulation materials in electrical equipment are used between a pair of electrodes; therefore it can be expressed as capacitors. Applying AC voltage to a capacitor with insulation materials causes an energy loss due to the leak current, the dielectric polarization, and the partial discharge. Because of this, the phase of the capacitor current is more delayed than that of a zero-loss current (reactive current) flowing in an ideal insulation material. The delay angle is called "Dielectric Loss Angle", and the tangent is "Dielectric Loss Tangent" (tanδ). Please refer to the technical guide explained in detail.

Multi Channel Optical Fibre Verification
-
The multi-channel optical fibre test system is used in the development and qualification of single mode optical fibres. The fibres are exposed to environmental influences in a climatic chamber in order to analyse the data on insertion loss and reflection. In addition, the current temperature in the climatic chamber is documented. Insertion loss measurement is performed with the help of an optical power meter, laser sources and optical switches. An Optical Time Domain Reflectometer (OTDR) from Exfo is used for the reflection measurements. The system was designed for the simultaneous characterization of 15 sample fibres and one reference fibre.
