. Type of current source: electronic constant current generator, driven by a discharging capacitor.
. Current generation duration: minimum 30 ms, according to the test current and the load.
. Capacitor charging time: 60 s.
. Maximum test voltage: 18 V.
. Test mode selection. With single test, the resistance value is displayed. With Circuit Breaker test,
the screen shows a table that collects the measurement of all phases.
. NOTE: during the first 4 ms, the resistance measurement is affected by the connection leads
inductance.

YNAMIC RESISTANCE MEASUREMENT
(OPTIONAL)
With this measurement it is possible to record the main contact resistance during the CB close.
The CB is open prior to test start: CBA2000 issues the Close command; as the contact closes, the
test current passes through the contact, and CBA1000 measures the contact resistance variations
during the close movement.
. Test current, resistance ranges and other characteristics: as for the static resistance measurement.
. Unlike the static resistance measurement, the test result is not a table of resistance measurements:
it is the resistance profile during the test, along with voltage and current profiles.

EST SET CONTROL
. The control is local, via keypad, selectors and display: no PC control is necessary.
. Keypad: 12 keys, numeric plus alphabet: it allows inputting all test references. The arrangement is
the same as portable phones.
. Two dedicated pushbuttons for test start and sequence selection.
. Numeric encoder with pushbutton for menu selection (see below the selections list).
. Five pushbuttons as menu shortcuts
. As the test is started, a buzzer warns the operator.
. The graphical display has the following main features:
-
Type: transflective LCD;
-
Pixels: 320x 240;
-
Backlight color: white;
-
View area: 122 x 92 mm;
-
Displays: menu selections prior to test start; then, current waveforms, contact inputs (main –
resistance), auxiliary inputs, analog input (those enabled). For dynamic resistance, it is
possible to display the resistance profile, along with voltage and current profiles.
. Memory size: 256 Mbytes (approx. 500 results).
. Maximum record length: 200 s.
. Capability of saving and re-calling up to 64 test settings.

ATA MANAGEMENT
The communication to the PC can be performed via two communication ports:
. RS232; baud rate 57600;
. USB.
Test results can be saved into an USB pen memory: this allows transferring all test results to the
office without the need of transporting the test set.
