Appendix E: Minimizing System Self-Heating
Follow the procedure outlined below to avoid any unnecessary heat generation in excess
of ~1°C.
1. Charge the system using a 12 V power supply. 12 V is the minimum required
by the SLICE system; anything in excess will contribute to heat generation.
2. Do not connect your PC to the system while it is charging. While this prevents
checking system status, continual PC communications keep the microprocessor active.
If the battery is not completely discharged and you do not want to wait the maximum
recharge time (1 hour), you may wish to implement a hardware interface that allows
you to check battery charge status. When the input current drops to 75 mA, the battery
is fully charged.
3. Complete the software auto-arm sequence and disconnect the system from
the PC and power supply within 2 minutes. Completing this step quickly minimizes
system and sensor self-heating. Once auto-arm and disconnect are completed, the
system is in a low-power state and awaiting initialization.
4. Initialize the system and perform your test quickly. To initialize the system,
press the LED/pushbutton switch for ≥3
sec. When the LED goes solid, the system is
ready for testing. Performing your test as soon as possible after system initialization
minimizes self-heating.
