PBT-300 Instruction Manual.pdf

This is a manual for a 12-volt automotive starting battery tester made by Midtronics, Inc. The tester is protected by various U.S. and foreign patents. For service, users should contact Midtronics for a Return Authorization number and return the unit freight prepaid. The product has a limited warranty of one year from the date of purchase, covering defects in materials and workmanship.

To test a battery out-of-vehicle, users should clean the battery posts or side terminals with a wire brush and install lead terminal stud adapters for side-post batteries. For in-vehicle testing, users should turn off the vehicle and all accessory loads, and remove the surface charge by turning on the headlights for 30 seconds.

The tester has a display and buttons for selecting the rating system (CCA, SAE, DIN, IEC, or EN) and performing battery and starting system tests. The test results are indicated by top-panel LEDs (green, yellow, or red) and the display shows the voltage and available power.

The manual also provides troubleshooting tips, such as checking for bad connections, excessive electromagnetic interference, and poor connections between the battery cables and the vehicle. Additionally, it includes instructions for performing starting system and charging system tests, and interpreting the results.
