PST-900X ProSeries Battery Tester with a Printer

It is also helpful in evaluating 12 & 24 volt charging systems. It has a 16 Character LCD with Adjustable Backlighting. Includes Case, Clamps, Batteries.

Before you start testing - Precautions - (from the user manual)

Be sure the area around the battery is well ventilated while the battery is being tested.

Clean the battery terminals. Be careful to keep corrosion from coming in contact with your eyes.

Inspect the battery for a cracked or broken case or cover. If the battery is damaged, do not use the tester.

If the battery is not a sealed maintenance free battery, check the level of each cell and if necessary, add distilled water until the battery acid reaches the level specified by the manufacturer. This helps purge excessive gas from the cells. Do not overfill.

If it is necessary to remove the battery from the vehicle to test it, always remove the ground terminal from the battery first. Make sure all accessories in the vehicle are off to ensure you do not cause any arcing.

ROV Metal Oxide Varistors Raychem

The ROV device's high current-handling and energy absorption capability, fast response, and low cost can make it suitable for use in line voltage applications.

ROV Metal Oxide Varistors Raychem

"ROV metal oxide varistors help protect power systems from damage caused by transient overvoltage faults such as lightning, power contact, and power induction. Suitable for a broad range of applications, ROV devices help protect sensitive electronic equipment from potential power surge damage by clamping high-energy, short-duration impluses."

ROV Metal Oxide Varistors Raychem Tyco

"An ROV device is a varistor fabricated using a Zinc Oxide (ZnO) powder, sintered with other metal oxide ceramics. The resulting structure is a polycrystalline ceramic that consists of distributed ZnO grains, separated by other metal oxide ceramics."

Raychem Circuit Protection Products

"A varistor is a variable resistor-a voltage dependent, non-linear device whose resistance decreases as the voltage applied across the device increases. "

ROVs can also be used to help protect electrical equipment from damage caused by large voltage or power transients on the AC Mains inputs. In a coordinated circuit protection scheme the ROV can be paired with a PolySwitch overcurrent protection device to help improve equipment reliability and fulfill IEC-61000 test requirements.
