CAUTIONS Warning Before using the instrument, please read this manual carefully for proper operation. Always perform automotive testing in a safe environment. Wear safety eye protection that meets ANSI standards. Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine parts. Operate the vehicle in a well ventilated work area: Exhaust gases are poisonous.
USING THE TEST TOOL BT250 Tool description Contacts the circuit or component Probe Tip to be tested. Illuminates dark work areas or work Head Lights areas at night. LCD Display Indicates test results. Clamps Auxiliary Ground Assists test as a ground lead.
BT260 Tool description Contacts the circuit or component Probe Tip to be tested. Illuminates dark work areas or work Head Lights areas at night. LCD Display Indicates test results. Allows you to conduct a positive or negative battery current to the tip for Power Switch activating and testing the function of electrical components.

● Before you test a circuit or component, be sure your tool is in Quick good order by doing a quick self-test. Self-Test ● With the tool connected, perform a quick self-test. The power switch is a momentary rocker switch located on the tool’s body.
IMPORTANT: When powering-up components, you can increase the life of power switch in the tool if you first press the switch, then contact the tip to the component. The arcing will take place at the tip instead of the contacts of the switch. Circuit This product has automatic short circuit protection, its internal breaker...

AC voltage ● While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the Max. voltage, the Min. voltage, frequency and duty cycle. Resistance ● While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the resistance between the tip and auxiliary ground lead.

Tone On / Off While the tool in this mode, just do a quick press of the mode ● button to toggle the tone on or off. While quickly pressing (a quick press and release) the mode button, if a short high beep is heard, this means the audio tone is turned on.
TEST APPLICATIONS ● Voltage & While the tool is in DC Voltage mode, contact the probe tip to Polarity a POSITIVE circuit. The red LED will light and the LCD testing displays the voltage with a resolution of 0.1V. If the beep is turned on, a high pitched tone will sound.

● In other cases, the LCD only indicates the resistance value. ● If the resistance value is greater than 200kΩ , the LCD will show “0L”. There is also another way to prove continuity of connections to ground or battery. Power up the connection using the power switch.
Signal Once you extract a DTC from the vehicle and realize that trouble- circuit shooting begins with some kind of sensor circuit, there is a quick testing test you can perform to verify the code. Testing your sensor is easy while using the tool. For example, you suspect there is a problem with your M.A.P.
to your component. With the power switch rocked forward, power will flow from the positive lead on the battery into the probe tip, through the tip into the component’s positive terminal, into the component and out of the component, through the auxiliary ground lead and back into the tool, and back to the vehicle battery’s ground.

NOTE: When powering up components, you can increase the life of power switch if you first press the switch, then contact the tip to the component. The arcing will take place at the tip instead of the contacts of the switch. While the tool in DC Voltage mode, contact the probe tip to the Activating negative terminal of the component, the red LED should light.
With this function, if you are contacting a protected circuit, a vehicle’s fuse can be blown or tripped if you apply ground to it. Probe the suspected ground wire or contact with the probe tip. Checking for bad ground ● Observe the green LED.
