3. Настройка

3.1 Устаноўка батарэі

1. Знайдзіце вечка батарэйнага адсека на задняй панэлі прылады.
2. Remove the cover by twisting or sliding it according to the markings.
3. Устаўце дзве (2) батарэйкі тыпу AAA, сочачы за правільнай палярнасцю (+/-), як паказана ўнутры адсека.
4. Надзейна заменіце крышку батарэйнага адсека.

3.2 Пачатковае падключэнне

1. Ensure the system to which the gauge will be connected is depressurized or isolated.
2. Carefully thread the 1/8'' NPT fitting of the digital pressure gauge onto the appropriate port of your HVAC or refrigeration system.
3. Tighten the connection firmly by hand, then use a wrench for a final snug turn to prevent leaks. Do not overtighten.
