    Processor: industrial ARM process chip Display: 4-digit nixie tube Auto height range: 2~30mm Height adjustment accuracy: ± 0.5mm Power supply: DC24V, 3A Working temperature: 0~40℃ Current of driver inside THC: 1.8A (AHa-S2) and 3A (AHa-M2) Technical Features 1. Height & sensitivity adjustment knob...
  • Page 4: Installation Dimension

    The height and the sensitivity can be statically or dynamically adjusted with the knob, and the value is saved in real time so that the operation is easier and faster. In addition, the pulse adjustment knob can be used longer than the contact potentiometer.
