Panel Mount Tachometer Model DT-5TG (VDC) Instruction Manual Features One of the most advanced on the market today, this microprocessor-based panel tachometer not only mea- sures rotational, linear and flow rate speeds, but can also function as an elapsed time counter and ratio meter. By choosing the desired input/output module(s), you can design virtually any system imaginable. ! Mounts easily — no brackets or screws or any other hardware needed. ! Tolerates a wide variation of voltages. ! Immune to electrically noisy environments. ! Programmable parameters and functions via front panel membrane push-button switches. ! Accepts a variety of input and output modules ! No need to remember mathematical formulas. ! Highly accurate. Dimensions (mm) ! Self-testing. Operational Precautions ! If the unit is used in a caustic environment, we suggest you use a NEMA 4X enclosure. ! Keep unit free of vibration and shock. ! When installing unit, keep power and sensor wires separate. Tie cable shield to terminal E (earth ground). ! After inserting wires, tighten terminal screws securely.
