MAN# 650051-A
GAUGE RANGE AND DISPLAY:
The vac/boost reading will display pressures from 22 inHg to 85 psi at sea level. There is
a separate boost warning output, WRN2, that is adjustable and can be used to trigger events
based on boost pressure. The boost warning levels are adjustable along with the update rate.
A negative sign indicates vacuum and the decimal point is also absent, below are some sample
readouts.

The temperature gauge is designed to operate from about 32 to 400 degrees Fahrenheit
and is intended for transmission, water, or oil temps. The sending unit required is SEN-04-3 a
32-400 ºF (0-200 ºC) range sensor. Because of the wide temperature span, the gauge may not
be as accurate below 100º F (38ºC).
The EGT gauge uses a thermocouple sensor to measure the temperature. The
thermocouple consists of a screw-in exhaust sensor and the cable which connects it to the
gauge control unit. The EGT gauge will operate and read correctly between the temperature
range of 150 – 1750 ºF(65 – 955 ºC). Because of the nature of the sensor used, the gauge will
not read cold temperatures.
