Battery
The VC4000 has a
semi-permanent
internal battery pack that will
run for at least 6 hours before it needs recharging. The battery pack
can be changed by the user if it does not hold a charge anymore.
The unit can be operated from the battery or plugged into a vehicle
’s
accessory jack (cigarette lighter) while testing. The battery will
charge while plugged into the vehicle. Accessories such as GPS will
discharge the battery quicker since they draw power from the
VC4000. It can also be powered and recharged from the wall
adapter. Recharging will take up to 3 hours. While charging, the
charging indicator on the front will light and if the unit is turned on the
battery gauge on the display will show arrows.
Turning on and off
Hold the power key for about
1 second
to turn the unit on. To turn
the power off hold the power key for about 1 second until the unit
beeps and displays a message to release the power key.
Safety Circuit
The VC4000 has safety circuits in place for accidental shorting or
reverse polarity of sensors or power input. If a sensor draws too
much current it will shut the power off to the unit. Sometimes when a
sensor is plugged in when the VC4000 power is on the unit will shut
off due to the inrush current when the sensor first powers on. This is
why we recommend plugging in all accessories with the power off.
Static Shock
If the unit is struck with ESD (electrostatic discharge) the display may
go blank, or less likely the unit may shut off. Push a key on the
keypad to see if the display comes back. You may have to get back
to the READY screen to make the display re-appear.
