DC voltage

While the tool in this mode, contact the

probe tip to a circuit, then the LCD display

will read the DC voltage with a resolution

of 0.1 volt.

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. If a short low

beep is heard, the audio tone is turned off.

This function is invaluable when working in bright

areas where LED illumination alone is not sufficient.

The audio feature may be disengaged when desired,

such as for applications where the tool will be

connected to circuits for long periods of time and the

audio could become annoying.

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.

Test Applications

Voltage & Polarity Testing

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. If the beep is turned on, a high pitched 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. If the beep is turned on, a

low pitched tone will sound.

If contact the probe tip to an OPEN circuit, neither of the LED will light.

Continuity Testing

While the tool is in Resistance mode, using the probe tip

with chassis ground or the auxiliary ground lead, continuity

can be tested on wires and components attached or

disconnected from the vehicle ' s electrical system.

When the probe tip is contacting a good ground, the LCD

will indicate "0.0Ω " and green LED will be on. If the tone

feature is turned on, a low 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. If the circuit breaker trips you know

that you have a good solid low resistance connection.

NOTE: You can use the probe tip to pierce the plastic

insulation on a wire. This means that you can test the

circuit without disconnecting anything.

Signal Circuit Testing

Once you extract a DTC from the vehicle and realize that troubleshooting begins with some

kind of sensor circuit, there is a quick 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. Sensor circuit, then follow the

procedure involved with testing this sensor:
