![]() Many accessories are also available for additional tests such as pressure transducers, ignition adapters, etc. Oscilloscopes/lab scopes/waveform viewersĪs a general rule, this category of tools will provide the most complete set of data, in most cases, when testing the functionality as well as the amount of current going to and through a circuit. Voltage spikes or varying voltages while charging during programming may cause damage to computer modules. Glass mat and gel cell battery chargers typically utilize a slower charge rate and may be temperature regulated, while flooded batteries are able to use traditional chargers because they are not apt to overheat while charging.Īn additional concern when purchasing a battery charger or maintainer is to assure it has the ability to deliver “clean” power in order to be useful when programming computer modules. ![]() Due to different types of batteries (flooded, gel cell and glass mat) having different requirements for charging, it is necessary to have a battery charger that is capable of charging each type without damaging the battery. Not to be confused with battery and charging system testers, considerations for battery chargers today should include the types of batteries the unit services and how fast can the unit charge the battery. The battery monitor works with the PCM to evaluate the battery and to adjust the charge rate to extend battery life.ĭepending on the vehicle, resetting the BMS can be performed by using a scan tool, or a stand-alone tool designed specifically to the task. Many late-model vehicles now require resetting the Battery Monitor System (BMS) after servicing the charging system or replacing the battery. Many battery/charging system testers have the ability to print a record of the results that may be stored with the vehicle records and provided to the customer. It is necessary to utilize a quality battery/charging system tester to load test the battery and to determine if the charging system has the ability to perform under all conditions. ![]() Most late-model vehicles utilize the PCM to control battery charge rates based not only on load demands, but on the quality of the battery as well. ![]() Battery and charging system testersįirst and foremost in any electrical test it is important to evaluate the battery and charging system. Since so much of today’s vehicles rely on electrically driven components it is important to understand the role of different tools and equipment in diagnosing electrical systems correctly and efficiently.Įven though many of the tool categories are able to perform electrical tests on circuits and components, some types of tools are better than others by either improving efficiency or the quality of data the tool provides. Oscilloscopes/lab scopes/waveform viewers.For manual actuation the TW18H with hand lever is available and for pneumatic applications the TW18V with valve button is the right choice. The quick connector is available for low pressure up to 50 bar and high pressure up to 350 bar. The higher the test pressure, the tighter the WEH® Connector will clamp itself onto the test piece port thus providing added safety for operators. On frequent connection and disconnection considerable time and cost savings are achieved thanks to automated processes. The pneumatic actuation for external manual, semi or fully automatic control systems is effected via an external valve. No additional thread sealants are required, time-consuming and expensive clamping and testing devices are eliminated. The safe and pressure-tight connection to standardised male threads is established in just seconds – without tedious hand tightening. The WEH® TW18P connector is the perfect tool for automated pressure, function and vacuum testing during production and rated for pressures up to max. WEH® Leak Test Quick Connector TW18P for vacuum and pressure testing up to max.
