ETAS Hardware description
• Adjustment and calibration values of the Isolating Measurement Probe
CBN101.1/CBN107.1,
• Information about the required measuring range.
If the Isolating Measurement Probe CBN101.1 or the Isolating Measurement
Probe CBN107.1 is operated with a customer-specific application software that
uses procedures in accordance with TEDS standard and if the application soft-
ware is adjusted accordingly, the following automatic functions can be imple-
mented:
• automatic setup of the power supply of the Isolating Measurement Probe
by the supplying A/D module,
• automatic transfer of the individual adjustment and calibration values for
the combination consisting of Isolating Measurement Probe and A/D mod-
ule,
• automatic setup of measuring range for the Isolating Measurement Probe
in the customer-specific application software.

Fig. 2-2 Use of the Isolating Measurement Probe
Typical applications are the monitoring of voltages in the high-voltage electrical
system, e.g. at the drive battery, at individual cells of the drive battery or at DC
links (see Fig. 2-2 on page 17). With the help of the voltage measurements, it is
possible, for example, to measure the charge state of the drive battery, the
behavior of the battery under load, fluctuations in the high-voltage electrical sys-
tem or the targeted discharge of the battery in safety-critical situations indepen-
dent of the ECU.
