Thermal Compensation
Thermal Compensation: For thermal compensation, the QS873A Voltage/Thermal probe (VT-Probe)
and its associated cables must be ordered. Refer to Section 5 for details on their interconnection, and
Section 9 for more information on VT-Probes. The probe is provided with a weatherproof case.
Thermal Compensation/Voltage Monitoring: When voltage monitoring for battery string voltage
imbalance detection is to be implemented in addition to thermal compensation, the VT-probe and its
associated cables must be ordered. Refer to Section 5 for details on their interconnection, and Section
9 for more information on VT-Probes and voltage monitoring.
