INTERNAL POWER (TESTBOOK 1)
To provide brief "stopgap" power while unplugged,
TestBook has an internal nicad battery. The internal
battery is located behind the dummy panel at the
front of TestBook. It will provide between five to ten
minutes of use on a full charge. It is only meant to
provide power when moving TestBook into and out
of a vehicle before and after a road test. During the
road test itself, you must use the Road Test Power
Supply - which is described in the next section.
When using battery power, the light on the front of
TestBook will change from the green one adjacent to
the plug symbol to the amber one next to the battery
symbol. This amber light will begin to flash when the
battery power becomes low. This means that the
unit will shut off after a short period of time if you do
not plug it back into an external power supply.
NOTE: The internal nicad battery
recharges whenever TestBook is plugged
into an external power supply - even when
Testbook is not switched on.
NOTE: As with any nicad battery, when the
TestBook internal battery becomes
drained, a period of at least two hours
must be allowed for it to recharge. If you have
removed the power supply with TestBook
operating and the amber light has started
flashing, this indicates that the nicad battery is
nearly drained. If TestBook is connected to a
power supply for only a short period of time after
the amber light has been allowed to flash, the
battery will not have recharged sufficiently to
power TestBook for the normal 5 to 10 minute
ROAD TEST POWER SUPPLY
One of the major advantages of TestBook is that it
can be taken out in a vehicle to carry out diagnostic
work during a road test. To do this, you must use the
Road Test Power Supply. Carry out the following
steps when using the Road Test Power Supply. You
do not need to turn TestBook OFF.
1. Connect the Road Test power Supply to the
battery of the vehicle to be road tested.
Connect the red cable to the battery "+" post.
Always double check that you have connected
the red cable to the correct, positive terminal
before going on to connect the black cable to
the battery "-" post. This is very important, as
the polarity must NOT be reversed.
2. Switch off TestBook’s power supply at the
power point on the side of the trolley.
3. Unplug the power supply from TestBook.
4. Plug the other end of the Road Test Power
supply into TestBook’s power port.
5. Return TestBook to a mains power point as
soon as you finish the road test.
6. When transferring TestBook to and from the
Road Test Supply, remember the limited time
available on the internal battery - don’t let
anything else distract you while doing this !
7. Allow at least two hours to fully recharge the
internal nicad battery. The battery recharges as
long as TestBook is plugged in, even when the
unit is switched OFF.
