PST-900X ProSeries Battery Tester with a Printer

This is 3 Testers Battery, Charging and Starting in one instrument. Easy to use with 3 Button Operation and used for testing 6 & 12 volt batteries.

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.

BOP high speed power operational amplifiers

BOP are high speed power operational amplifiers that can be used to provide dynamically agile voltage for test and simulation. They are not general purpose power supplies. By the nature of the bipolar high speed design, they do not have any energy-storage noise discriminating output capacitors.

SLM Family Electronic Loads

SLM Family Electronic Loads The SLM family includes 11 models of fully programmable, single input AC or DC modular electronic loads. DC models are offered to test power supplies, battery chargers, battery discharge, power supply transient response and integration into ATE systems. AC models are ideal to test low power inverters.

SL series Electronic Loads – Sorensen

The DC models support operation in Constant Current, Constant Voltage, Constant Resistance or Constant Power mode as well as a short simulation. Engineers have ultimate control of current waveforms by using either the analog input or CC dynamic mode. An analog input (single input DC models) allows arbitrary current waveforms up to 20kHz with an external 0-10V signal……..
