Digital Instrumentation

Model 3000R

FEATURES

▶ Multiple functions in one programmable unit:

– Lower overall stocking requirements.

– Reduced installation time and labor.

– Reduced vehicle instrumentation count.

– Ease of ordering.

– Volume pricing/purchasing advantages.

▶ Field programmable maintenance monitor allows 

dealers and/or users to program maintenance 

intervals for their specific application.

▶ Optional settable hour meter allows replacement of a 

failed hour meter without loss of total elapsed time.

▶ Flexible output modes include flashing LCD 

segments, panel mounted LED and FET (0.5A) which 

allows the equipment designer to define critical 

parameters and to choose appropriate notification 

methods, such as alarms or buzzers.

▶ True Curtis battery monitoring technology means 

proven algorithm protection capabilities providing 

reliable state of charge information.

▶ Sealed front panel buttons allow easy:

– Setting of maintenance interval.

– Setting of battery monitoring profile.

– Re-setting of maintenance hours.

– Setting of total hour meter (optional).

The Curtis enGage® II is a dual function, microprocessor based instrument that can be factory or user defined to 

monitor various functions including fuel, temperature, pressure, voltage, battery state of charge and maintenance/

status. Industrial and commercial vehicles including: material handling, outdoor power and construction equipment, 

engine driven stationary devices, commercial cleaning equipment, golf/lighton- road and other mobility aids. Also 

ideally suited for monitoring scheduled maintenance, warranty and leasing intervals. Manufactured under ISO 9001 

certified Quality Management system. UL recognized & CE certified.
