Test Purpose: The Amp Find mode allows you to Identify Amperage on a circuit. This feature is watching for a stabilized voltage reading over a certain threshold. If amperage is flowing through a fuse and the voltage drop is high enough the application will provide the “Amps Found” notification. If the “None” notification is showing the tool show no consistent voltage drop reading. Test Setup: - Sample rates: 256 (32) - Bottom Channel: Voltage DC or Auxiliary Voltage DC Top Channel: N/A Test Procedure: - Place Leads on tool to Voltage DC or Auxiliary Voltage DC - Use Probe Tips - Set the Data Intelligence menu to Amp Find - Put Probe Tips across the terminal tops of a single Fuse - Ensure probe tips are securely on top of fuse terminals for accurate reading. Any voltage reading = “Amps Found” This setting is highly sensitive so ghost voltage will identify as amps found. Once reading stabilize on circuit reading will be accurate. Recommendations: - Any draw over 30mA can kill battery over time. If Amp Find, “Finds Amps” shows it is suggested to verify the amperage reading is in alignment with what is expected. For example if a dome light is on, ensure the amperage draw is as expected. - Once a circuit is found with “amps found” you can verify circuit has amp draw by testing with fuse test. By selecting the fuse type and the fuse size. - Once amperage is found that is abnormal or not... (More)

Test purpose: This test is designed to monitor the resistance value of the thermistor and determine if it is within range of the operating specifications. Thermistors are either NTC or PTC type and their resistance values are variable depending on the temperature that they are sensing. A thermistor can either be open, shorted or operating correctly or incorrectly. In this test we are looking to determine if the resistance change in the thermistor is smooth and consistent over the increase and decrease in temperature. Although this test is not a definitive “pass / fail” or “green light / red light” the tool is automatically set up for a fast resistance capture with stable readings and ranged correctly. Once connected to a thermistor, the graphing screen will be the way to monitor output. Tool Setup: • Top Chanel: N/A • Bottom Channel: Resistance - Ranged to 10MΩ • Set Min/Max to Max • Speed: 64MS (256) or (4000 Hz 256 SMPL) Test Procedures: • Place Leads on tool to Ohms and Common • Use Probe Tips on leads or clamps • Remove the thermistor from a power source. • Connect the positive probe tip or clamp to the positive output of the thermistor • Connector the ground probe tip or clamp to the ground of the thermistor • Look for “out of range” , a “stuck” Ω value or a slightly fluctuating μΩ reading. • Set the Meter Mode to Graph • Begin to heat up the thermistor. • Watch the...
