I'm trying to get a RPM reading using a Monarch Tachometer ROLS-P . How do i wire the sensor to the 7-pin digital input of a DEWE43?

I have attached the datasheet. 'Monarch-ROLS-1071-4851-113.pdf '

Pin Assigment is

tip = signal

middle = +V

base = drain.

Dear Pieter,

Thank you for your question. Tachometer should be connected on counter connector. I assume this should work properly.

tip = signal pin 1

middle = +V pin 6 +12V

base = drain. pin 7

Kind Regards,

Hi...the least expensive and easiest arrangement is to utilize an alternator detected tacho measure. I have a laser rpm gadget to precisely align it.

I surmise the following issue is to work out connection between alternator waveform and the motor rpm - apparently an element of pulley sizes and so forth. Passes on one size fit all or do you need to purchase a particular measure for a particular proportion I wonder?
