4.1.
Basic Connections (fig.2)
4.1.1.
unroll the probe cable. connect the red battery clip to the PositiVe terminal of the vehicle’s battery. connect the black battery clip to
the NEGATIVE terminal of the vehicle’s battery.
4.1.2.
Alternatively use the 12V vehicle accessory socket adaptor instead of battery clips.
4.1.3.
When the probe is first connected to the battery, the probe will go into voltage mode.
4.1.4.
the audible indicator will be heard and the two led work lights will switch on to illuminate the test area of the probe.
4.2.
Quick self test
4.2.1.
Press the power switch forward to activate the probe with a positive voltage. the positive led should light red and the lcd
screen will display the battery (supply) voltage. if the audible indicator feature is turned on, a high-pitched tone will emit. release the
power switch, the led will turn off and the audible indicator will cease.
4.2.2.
Press the power switch rearward to activate the probe with a negative voltage. the negative led should light green and the lcd
screen will display ‘0.0V’. if the audible indicator feature is turned on, a low-pitched tone will emit. release the power switch, the led
will turn off and the audible indicator will cease. the probe is now ready to use.
4.2.3.
if the tool failed to operate, depress the circuit breaker reset button on the right hand side of the housing and repeat the test.
4.3.
circuit breaker
4.3.1.
the tool is short circuit protected. the internal circuit breaker will trip in case of overload.
the maximum current rating is 8amps.
4.3.2.
When the circuit breaker is tripped, the LCD will display as (fig.3). All the other functions of the tool will remain active. When the circuit
breaker is tripped, the tool will not be able to energise the probe tip when the power switch is pressed. intentionally tripping the
breaker and using the tool to probe can be considered a safeguard against unintentionally pressing the power switch.
4.4.
operating modes
4.4.1.
voltage
- With the tool in this mode when contacting the probe tip to a live circuit, the lcd screen will display the voltage of the circuit
to the nearest 0.1Volt (fig.4).
4.4.2.
scope
- With the tool in this mode contacting the probe tip to a live circuit, the lcd display will read the maximum voltage,
minimum voltage, frequency and duty cycle (fig.5). There are 22 settings in scope mode. The display automatically changes the ‘Y’
axis scale to give clearer readings.
4.4.3.
resistance
- With the tool in this mode, contacting the probe tip to a component, the lcd display will show the resistance between
the probe tip and the auxiliary ground lead (fig.6).
4.4.4.
Audible Indicator On/Off - With the tool in this mode, press and hold the mode button to change the function of the audible indicator
(fig.7).
5. testing proceDures
5.1.
voltage and polarity test
5.1.1.
With the tool set in voltage mode, when the probe tip contacts a PositiVe circuit, the red led will light and the lcd screen will
display the voltage to the nearest 0.1V. If the audible indicator is activated, a high pitched tone will emit (fig.8a).
5.1.2.
When the probe tip contacts a NEGATIVE circuit, the green LED will light and the LCD screen will display the voltage to the nearest
0.1V. If the audible indicator is activated, a low pitched tone will emit (fig.8b).
if the probe tip contacts an oPen circuit, neither led will function.
