3.1 basic connections (fig.2)
3.1.1 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.
3.1.2 Alternatively use the 12V vehicle accessory
socket adaptor instead of battery clips.
3.1.3 When the probe is first connected to the battery,
the probe will go into voltage mode.
3.1.4 the audible indicator will be heard and the two
LED work lights will switch on to illuminate
the test area of the probe.
3.2 Quick self test
3.2.1 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.
3.2.2 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.
3.2.3 if the tool failed to operate, depress the circuit
breaker reset button on the right hand side
of the housing and repeat the test.

3.4.2 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.

3.3 circuit breaker
3.3.1 the tool is short circuit protected. the internal
circuit breaker will trip in case of overload.
3.3.2 When the circuit breaker is tripped, the LcD will
display as below (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.
3.4 operating modes
3.4.1 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).
