Madman EMS-3 Operating Manual Page 2
1 Features
Large 1.8” high resolution 160x128, sunlight readable, wide viewing angle, 1000 cd/m2 TFT LCD display
Battery voltage display, the EMS-3 can measure voltages up to 30V (Can be used in 12V and 24V vehicles)
and contains a programmable low/high voltage alarm to automatically catch alternator failures, drive belt
failures and bad batteries
Hour meter display to determine actual engine running time with 1/10 hour resolution
Built in service interval reminder based on vehicle ignition on time
EGT (Exhaust gas temperature) can be displayed in degrees Celsius or degrees Fahrenheit from -100ºC
to 1200ºC (-148ºF to 2192ºF) and contains a user settable high alarm.
Includes an EGT trend graph display
Includes linearization of K or J Type thermocouple probes and is cold junction compensated for greater
accuracy
4x Universal analog input channels that can be configured for pressure or temperature.
Pressure sender measurement with user settable high and low alarm. Pressure sender inputs can be
from a Fuel, Oil, Manifold, Turbo Boost or an Auxiliary pressure sender.
Temperature measurement with user settable high and low alarm. Temperature sender inputs can be from
an Oil, Coolant or an Auxiliary temperature sender.
Oil Pressure warning alarm from oil pressure senders that have a switch output
Coolant level absence/presence detection by the means of AC signal probe excitation. The EMS-3 can
use inexpensive probes such as stainless steel screws to determine the coolant level. The EMS-3 can also
be used with float level type sensors. The Coolant level detection circuit also has a programmable switch
time to prevent false alarm messages when driving over rough terrain
Fan control output for on/off temperature control
All senders linearized for additional accuracy
Each sensor display can be individually enabled or disabled
Includes an external audible alarm output (The sound can be turned on/off, for example game viewing)
Dual external alarm outputs
Ambient light sensor for automatic or manual backlight control
On-board voltage reversal and over voltage protection for harsh vehicle environments
Standard 2” (52mm) circular enclosure
SMPS (Switch mode power supply) for use in both 12V and 24V vehicles
Maximum values of all readings are recorded
Easy to use menu system for user parameter setup
Field upgradable firmware via the RS232 interface
1 year limited warranty
