Introduction
Introduction
Electronic inclinometer IM330 is a device to measure ship hull posture,
including roll actual angle, roll period, roll amplitude, pitch actual
angle, pitch period, pitch amplitude, date, time, longitude and latitude,
and to send them to VDR. It also has alarm function for ship’s officers
to avoid dangerous situations and the alarm messages (date, time,
longitude, latitude, roll angel and pitch angel) are recorded in the
history for check.
Electronic inclinometer IM330 is based on the combination of
mechanical and electronic principle to provide the hull posture during
the ship sailing. The main unit (display) can be separately used with
the inclination sensor. The main unit can be mounted in the methods
of table, hang and flush, and the inclination sensor should be mounted
in horizontal direction and perpendicular to ship mast.
Definitions
Roll
motion around the longitudinal axis of the ship
Pitch
motion around the horizontal axis of the ship
Actual angle
momentary angle of roll or pitch referenced to a leveled
ship to port or starboard side, or to front or back side
Period
Time between two successive maximum values of actual
angle on the same side of the ship
Amplitude
maximum values of actual angle to port or starboard side,
or to front or back side

Introduction
System View
Electronic inclinometer IM330 consists of the main unit and inclination
sensor. The inclination sensor sends roll and pitch messages, in the
form of RS485 digital interface, to the main unit. There is digital and
analog display of the roll and pitch angles on the main unit. In the
meanwhile, the messages of date, time, longitude and latitude are
from GPS. And IM330 sends the roll angle and pitch angle to VDR, ECS
and so on.

Operation
Alarm
In the roll/pitch mode, press key [A], the words on the bottom left of
screen ‘Roll Mode’/’Pitch Mode’ change to yellow colors, and adjust
the knob to set the alarm value. Then press the key [A] again and the
words ‘Roll Mode’/’Pitch Mode’ return to white color. Succeed in Alarm
settings! If there is no operation in 10s, the words will become white
color automatically and not in alarm mode.
Power Failure
The LED on the front frame is used for power failure. The LED is green when
dual tracking power supply. When only single power supply is on, the LED is
red and the red words ’Power Failure’ is flashing on the left bottom with buzzer
alarm. Press any bottom to release the buzzer alarm.
Note, the main unit provides one interface, which can be used to connect with
the external alarm to improve the alarm effect!!!
Roll Mode
Press the key [R] to enter roll mode. On the screen, it shows roll
amplitude, actual angle (digital and analog), period, alarm setting
value, date, time, longitude and latitude.

7
Operation
Roll-Pitch Mode
Press the key [R-P] to enter roll-pitch mode. On the screen, it shows
roll mode (amplitude, actual angle, period and alarm setting value),
pitch mode (amplitude, actual angle, period and alarm setting value),
date, time, longitude and latitude.
Pitch Mode
Press the key [P] to enter pitch mode. On the screen, it shows pitch
amplitude, actual angle (digital and analog), period, alarm setting
value, date, time, longitude and latitude.

8
Operation
Zoom
In the roll/ pitch mode, press the key [Z] to zoom in or out the scale
of the analog angle display. The angle range in the analog display is
0°~90°(1°), 0°~45°(0.5°), 0°~18°(0.2°) and 0°~9°(0.1°).
Power
Turn on or turn off the power supply. When only one power supply is
disconnected, the power failure alarm will be on and press any key to
mute the buzzer.
Day / Night
Press the key to select the day mode or night mode.
Language
Press the key to select the language. The option is Chinese or English.
Forward
Page forward the history record in History Display.
History Display
Display history record which the main unit have recorded before,
including the date, time, longitude, latitude, roll angle and pitch angel.
Press the key [R], [P] or [R-P] to return the display of roll mode, pitch
mode or roll-pitch mode.

9
Operation
Backward
Page backward the history record in History Display.
Record Switch
Turn on or off the history record to select if recording navigation
messages. When the Record Switch is on, the words “Recording” will
be shown on the bottom left of the screen. Then the main unit will
record the messages, only when the actual angle is larger than the
value of the alarm. When the Record Switch is off, the words
“Recording” will disappear, and the main unit will not record the
messages anytime.
Knob
When the alarm value is set to yellow color, the knob can adjust the
roll or pitch alarm value. The setting range is OFF, 1°~45°. At other
times, it can adjust the screen brightness (12 levels) to apply in the
current environment by rotating the knob.

Installation and Calibration
The inclination sensor should be mounted towards the ship head and
in a horizontal direction perpendicular to the mast.
When calibration, the ship should be static and horizontal as much as
possible. After finishing the installation, press “”to show the
roll-pitch mode. If the actual angle of roll and pitch is not zero degree,
users should calibrate the roll-pitch angle. Press “”，“”and
“”in turn, and then the angle for roll and pitch change to zero
degree. So, the calibration is finished and saved as reference.
Please do not calibrate the inclinometer when the ship is sailing!
