DDING OPTIONS
It is possible to add options after the test set has been delivered; they are: four coil drive; internal
printer or voltage drop.
In this case, when you receive the option, first of all install it into the test set; then, power-on keeping
the START button pressed until the diagnostic test starts. At the end of diagnostic, the following
window is opened.
Selecting HW configuration, the following window is opened.
It is necessary to check the added option, so that the microprocessor learns that it has been installed,
and takes control of it.
With this selection, you can also input your password, that is blank at the beginning. After this, the first
message after power-on is “Input the password”. Take care, because if you lose it, it is hard to recover
the operation.

ALIBRATION
3.6.1 Introduction
With the same operation as above, you can enter the Calibration mode.
CBA1000 does not need to be calibrated, as metering circuits employ high stability components.
It is suggested to check the unit every 3 years, by comparing CBA1000 measurements to external
meters. Tests should be performed with an accurate multi-meter, that should guarantee a maximum
DC measurement error of 0.1%, both for voltage and current, and some high current sample shunts,
for the micro-Ohmmeter test. The adoption of lower-class instruments may cause false interventions,
that introduce errors into the test set.
