• Simplify manufacture by incorporate common components and circuitry.
• improve performance reliability by eliminating mechanical switches.
• eliminate calibration problems by removing the calibration pot on the PCB.
The PCB P/N remains the same as the original but the installation of PN-675280 Rev. “D” PCB for the
Digimatic II and DigiPulse Automatic will require a change in position of the “Coding Plug” to accept the
new Revision “D” board. More details and installation instructions are provided below.
