Features
Yokogawa Digital Indicator UM33A
• A 14-segment, active (PV display color changing function) color LCD display is employed.
Two five-digit, high-resolution displays are possible. Alphabet letters can be displayed in an easy-to-read manner. The guide display shows parameter names.
• Easy to operate
Navigation keys (SET/ENTER and Up/Down/Left/ Right arrow keys)are employed to facilitate making settings.
