Capacitor Module T24-BC2
This is used for batteries which have an internal resistance of greater than 150mOhms overcoming voltage
drops during high current phases of the low power mode cycle.
This problem becomes apparent when attempting to communicate with high peak current acquisition modules
such as a T24-SAf using the T24 Toolkit or power cycling when the battery is near the end of its life. In normal
operation (Low power mode) with an analog output module or the T24-SAf is connected to an uninterrupted
battery this module is generally not required.
Using lower impedance strain gauges (or multiple parallel strain gauges) exacerbates this problem.
Consult Sales for details. Alternatively fit an electrolytic capacitor across battery of 2000uF or greater. This
capacitor should be of low ESR (< 70mOhms).
