As you have no data to make calculations, trial and error will be the order of the day, as will be a rather crude approach to the problem.

The simple approach is to add a resistor across the monitor input as a shunt. Measure the resistance at present existing across the input and as first trial, connect a resistor of say four times this value in parallel. You will appreciate that reducing the value of this resistor, will further reduce sensitivity and increase the demand for current.

I would anticipate that a small carbon resistor should suffice in respect wattage. There will be problems of a mechanical nature in arranging connections and you will probably have to make up an in and out plug socket arrangement.
