• Equipped with a replacement time notification function.
• The white-color display further improves visibility and the color
universal design is used. And the Up/Down Keys make it easier
to use the Tachometer.
• Compatible with the ratings, characteristics, and functionality of
the H7CX-R-N.
Specifications
Ratings
*1.
Do not use the output from an inverter as the power supply. The ripple must be 20% maximum for CC power.
*2.
The display is lit only when the power is ON. Nothing is displayed when power is OFF.
