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.
