Advanced bqMTester Instructions www.ti.com
While the HPA495 Calibration Board includes an on-board temperature sensor, it is recommended that
you use external temperature sensors for the most accurate temperature calibration. For an external
temperature sensor, use the TI TMP100 (not supplied) and connect as shown in Figure 3. The software
distinguishes between the on-board temperature sensor and any external temperature sensor.
