IT1000 Basic Rate ISDN Tester
SALES: 0870 90 10 750
The B1 indicator will also flash briefly when the unit is first powered up to indicate that the unit is
performing a self-test. When it stops flashing the unit is ready to use.
The Pass / Fail indicator illuminates after a test is performed to give the result of the test. A green
light together with a rising tone from the internal speaker indicates a successful test. A red light
together with a falling tone from the internal speaker indicates a test failure.
You will notice that the LED indicators are also marked at the right hand side with a scale reading
from 10 Volts to >70 Volts. This scale is used in conjunction with the Line Voltage test to show the
actual voltage on the line from the exchange.
On the left side of the unit there are connectors for the ISDN line under test and for a laptop
computer or PC to enable more sophisticated tests to be carried out together with a power input
socket. The use of these connectors is explained fully below.
2.3.2 The rear panel
The rear panel of the unit has a hatch for the main battery which can be opened by slight downward
pressure where indicated and sliding the hatch upwards towards the top of the unit.
There are no other user controls inside the unit and it should be noted that removal of the case screws
will invalidate both the warranty and the safety approvals.
2.3.3 The battery
The IT1000 is battery powered to enable tests to be carried out in the field without the need for
additional power supplies.
A standard PP3 or MN1500 battery should be used. We recommend that only good quality Alkaline
or Lithium batteries should be used, such as Duracell™.
The unit can be supplied as an option with a high power rechargeable Nickel Metal Hydride battery
which will power the unit for between 6 and 10 hours depending on the tests performed. The battery
can be removed and recharged in the supplied charger about 1,000 times before a replacement is
needed.
The supplied battery contains compounds that may be hazardous to the environment and therefore
MUST be disposed of properly at the end of its life.
