Page 9: Operating Instructions
OPERATING INSTRUCTIONS 8.1 GENERAL DESCRIPTION The tool is ideal for reducing diagnostic time in all 6 to 30 volt vehicle electrical systems. After a simple hook-up of the tool to the vehicle’s battery, you can: • Determine at a glance if a circuit is positive, negative, or open without having to reconnect clips from one battery pole to another. -
Page 10: Auto Circuit Breaker
OPERATING INSTRUCTIONS 8.4 AUTO CIRCUIT BREAKER - FIG. 2 The tool is short-circuiting protected. Its internal circuit FIG.2 breaker will trip if it becomes overloaded. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload. When circuit breaker tripped, the LCD will display as Fig.2. -
Page 11: Frequency
OPERATING INSTRUCTIONS 8.7 FREQUENCY - FIGS. 5 - 7 While the tool in this mode, contact the probe tip to a FIG.5 circuit, then the LCD display will read the Max. Voltage, the Min. voltage and frequency. FIG.6 FIG.7 View of screen View of screen... -

Page 13: Diode
OPERATING INSTRUCTIONS 8.9 DIODE - FIGS. 10 - 11 The diode work mode is to test the polarity of PN junction of FIG.10 diode. Contact the probe and the black alligator clip to two electrodes of diode. After getting the result, exchange the position of probe and the black alligator clip to get the other result. -
Page 14: Test Applications
TEST APPLICATIONS 9.1 VOLTAGE & POLARITY TESTING - FIGS. 12 - 13 While the tool is in DC Voltage mode, contact the probe tip to a POSITIVE circuit. The red LED will light and the LCD displays the voltage with a resolution of 0.1V. A beep tone will sound. If contact the probe tip to a NEGATIVE circuit, the green LED will light and the LCD displays the voltage with a resolution of 0.1V. -
Page 15: Signal Circuit Testing
TEST APPLICATIONS In other cases, the LCD only indicates the resistance value. FIG.15 If the resistance value is greater than 100 kΩ, the LCD will show “0L”. There is also another way to prove continuity of connections to ground or battery. Power up the connection by using the power switch. -
Page 16: Activating Components In Your Hand
TEST APPLICATIONS 9.4 ACTIVATING COMPONENTS IN YOUR HAND - FIG. 17 While the tool is in DC Voltage mode, by using the probe tip in connection with the auxiliary ground lead, components can be activated right in your hand, thereby testing their functions. Connect the auxiliary ground lead to the negative terminal or ground side of the component being tested. -
Page 17: Activating Components In The Vehicle
TEST APPLICATIONS 9.6 ACTIVATING COMPONENTS IN THE VEHICLE - FIG. 19 While the tool in DC Voltage mode, contact the probe tip to the positive terminal of the component, the green LED should light, indicating continuity to ground. While observing the green LED, quickly depress and release the power switch forward. -
Page 18: Checking For Bad Ground Contacts
TEST APPLICATIONS 9.8 CHECKING FOR BAD GROUND CONTACTS Probe the suspected ground wire or contact with the probe tip. Observe the green LED. Depress the power switch forward then release. If the green LED went out and the red LED came on, a beep will sound, this is not a true ground. If the circuit breaker tripped, this circuit is more than likely a good ground. -
