How to determine failure levels for your batteries, the internal resistance measurement level, and cut-off voltage. Also gives a quick overview on setting up the Hioki 3554 Battery HiTester to conduct tests.

Takes on-the-spot measurements of the internal resistance, voltage and temperature of lead-acid batteries, principally for UPS and similar applications, without needing to shut off the battery. Instantaneous results, on a three-rank scale of Pass, Warning, or Fail, using a composite decision based on the internal resistance and the voltage. Resolution of 1 µohm, necessary for high capacity batteries (of at least 500 Ah). Includes Hioki 9460 clip type temperature leads. 

Infrared Solutions, Inc., a Fluke Company, has developed a new infrared technology called IR-Fusion™ that blends, pixel for pixel, visible and infrared images on a single display. This article describes the patent-pending, novel, low-cost approach to solving the parallax problem of combining images from separate visible and infrared optics.

From storm damage to every- day plumbing and roof leaks, moisture damage in residential and commercial buildings can be very expensive. The key is identifying and locating moisture problems before secondary damages escalate. Within the last few years, infrared cameras (thermal imagers) have become powerful tools for locating moisture problems in buildings. Instead of searching for moisture inch- by-inch with a moisture meter, an infrared camera provides the ability to scan an entire room in a matter of minutes. By locating the thermal changes from evaporative moisture cool- ing (EMC) in drywall, carpet, ceiling tiles, etc., inspectors can moisture map the entire building and isolate problems before providing an estimate for remediation. This article discusses the parameters and limitations when using infrared cameras to detect moisture inside buildings and homes.

"I have my thermal imaging camera. Now what do I do?"

In the past, establishing a preventive maintenance program has required a lot of tedious work and often just doesn’t work the way we think it should. The goal of a successful preventive maintenance program is to have easy access to historical data for each piece of critical equipment, so measurement trends can be monitored and maintenance downtime planned – preventing equipment down situations.

When a motor bearing fails, the motor heats up and lubrication begins to break down. The windings overheat and then the temperature sensor cuts out and stops the motor. Worst case, the shaft binds up, the rotor locks up and the motor fails completely.
