BVR Series -
IBEKO Power AB
Battery voltage recorders from BVR series are designed to serve as a support tool for cell voltage measurement during battery capacity testing.During capacity testing, cell voltage, temperature, inter-cell connection voltage, and specific gravity should be measured in order to determine failling cells in the string that should be replaced.Furthermore, IEEE standards for stationary batteries applications stipulate periodical measurement of overall string voltage, as well as cell voltage and temperature.The BVR Series is the perfect tool for that purpose. All measurements are automatically saved in device’s internal memory. Additionally, DV-B Win software helps the user to download all measured results. Furthermore, the user can create test reports and export them to various formats.BVR series includes two models: BVR11 and BVR22. These are rechargeable handheld devices intended for performing monthly battery inspections and support tools during capacity testing. The list of the applications of these instruments includes:Efficient supplement to BLU series of battery load units during battery discharge testingMonthly inspections of large battery banksAmbient temperature measurementCurrent measurement using current clampsUSB and Bluetooth communication with PCSimultaneous string voltage and current measurement to analyze a discharge test processThe BVR22 model provides Bluetooth communication with an external density meter, for transferring electrolyte specific gravity and temperature readings.

K&S Engineering and Scientific Ltd
The instrument is fully enclosed in a robust all steel enclosure mounted on castors and fitted with carrying handles. The control panel forms the top of the case, it is finished in high gloss light blue stoving with cutter engraved labelling, and is protected by a detachable lid. The EHT outlet is of a recessed type designed to prevent accidental contact with high voltages. Surge repetition is electronically controlled from 0 to 10 seconds, a single surge or a train of pulses can be selected by a panel mounted switch. Automatic discharge of the instrument is achieved by a gravity operated switch which is released on switching 'OFF' the instrument or on disconnecting the supply.

LXinstruments GmbH
Manufacturers of electrical or electronic products are required by law to carry out an electrical safety test before placing them on the market. This final test takes place at the end of the manufacturing process and is therefore also referred to as an EOL test (end-of-line). Depending on the prescribed standard and directive, the following parameters are tested:- Leakage current and discharge current- Insulation resistance or the insulation strenth- Dielectric strength or electric strength- Correct installation of the protective conductor (ground continuity and ground bond test)- Faultless functioning of the product under the conditions defined for intended use (function or run test

EMP -
Keystone Compliance
An electromagnetic pulse (EMP) is a short burst of electromagnetic energy that can be extremely damaging to electronic equipment. EMP energy can be transferred in the form of electromagnetic radiation, an electric field, electrical conduction or a magnetic field. Since EMPs have a short duration, their impact can occur across large ranges of frequencies. EMPs can be produced naturally, occur from man-made equipment. Natural EMPs include lightning strikes and electrostatic discharges (ESD), geomagnetic storms/coronal mass ejections of solar origin. Man-made EMPs include power line surges, pulses created by ignition systems, nuclear electromagnetic pulses (NEMP) and non-nuclear electromagnetic pulses (NNEMP).
