This Blue Ring Rester kit is an inexpensive and effective way to test any high Q inductive component. It is especially useful for doing a quick check on flyback transformers, line output transformers and other high frequency inductive components like deflection yoke windings and SMPS transformers. Hi Q = low loss inductive components. A shorted turn or coil will show no rings. A shorted FBT diode will show few or no rings. The LEDs on the left side show the Q of the device being tested, more lights = higher Q, i. e., no lights = short circuit, red = Bad or low Q, yellow = medium Q, green = Good or high Q. This kit will take 1-2 hours to build depending in experience. Full 1yr warrenty on parts.
The 231A can easily read the correct pin configuration of 10BaseT cable (category 5), 100BaseTx, 10Base2 cable (coax) and RJ45/RJ11 modular cables, 356A, TIA 568A, TIA 568B and Token Ring cables by comparing one transmitting end to the corresponding receiving end. With the remote kit, it can test cables installed far away either on wall plate or patch panel up to 1000ft away. It is easy to verify the cable continuity, open, short, and cross connect, featuring auto or manual scan for pin-out indicators.

The Amprobe solar power analyzer evaluates the energy output, efficiency, and placement of solar panels, helps determine the proper inverter size in solar power systems, and identifies malfunctioning cells on solar panels. It measures maximum power (Pmax), maximum voltage at maximum power (Vmaxp), maximum current at maximum power (Imaxp), voltage at open circuit, voltage present in system, current at short circuit, and percent efficiency to determine the actual power output of a solar panel in normal operating conditions. The operator can choose between an auto scan mode, for an overview of the power characteristics of a solar panel, and a manual scan mode, for focusing on a particular operating range or single test point for measurements.
The Amprobe SM-CAL1 is a sound meter calibrator for maintaining the accuracy of a sound level meter. It fits sound meters with microphones that have a diameter of up to 1/2 inch. It produces two fixed sound level signals, 94 decibels (dB) and 114 dB, and has an output frequency of 1,000 hertz (Hz). The calibrator operates on a 9V battery (included), and a low-battery indicator shows when the unit's batteries need to be changed. It meets European conformity (CE) directives and complies with American National Standards Institute (ANSI) and International Electrotechnical Commission (IEC) standards. The SM-CAL1 weighs 0.6 lb. (285 g), and it measures 4.9 x 1.9 x 0.5 inches (125 x 48 x 12.7) mm, H x D, where H is height, the vertical distance from the lowest to highest point, and D is diameter, the distance from left to right across the widest part of a circle).Sound meters measure sound pressure levels both to check acoustic fidelity and to verify compliance with noise pollution regulations in health and safety codes. The meters are used in a range of environments, including homes, schools, airports, automotive and machine shops, concert halls, recording studios, and hospitals. There are two classes of sound level meters. Type 1 sound meters have a wider frequency response and a tighter tolerance than type 2 sound level meters, and they are commonly used in applications that require precise measurements, such as research and law enforcement. Type 2 sound meters are less precise than type 1 meters and are used for taking general measurements, such as measuring noise levels in a machine shop. Sound level meters are weighted for frequency response according to their intended use. The most commonly used weightings are A, C, and Z. The A weighting imitates the response of the human ear to soft or moderate noise levels and can be used in most environmental noise measurement applications. The C weighting imitates the response of the human ear to loud noises and can be used in noisy environments. The Z weighting measures fla...
