Measurement alarm
Current speed alarm・Low: When Current speed falls below a set value (warning
value), it generates an alarm.
Setting alarm value [OFF, 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 ]kn
Ship speed alarm・Low: When ship speed falls below a set value (warning value),
it generates an alarm.
Setting alarm value [OFF, 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 ]kn
Bottom Depth alarm・Shallow: When becoming shallower than the set depth (warning
value), it generates an alarm.
Setting alarm value [OFF, 60]m 60m: Input by numeric key. (It is possible to
set within range (*1) of 5-500m.)
Timer alarm・Long: When the set time (warning value) is exceeded and it sails,
it generates an alarm.
Setting alarm value [OFF, 1:00 1:30 2:00 2:30]h
The timer is time that passes between the point “0” resets
(*2) with [RESET] key and present.
Trip alarm・Long: When the set distance (warning value) is exceeded and it
sails, it generates an alarm.
Setting alarm value [OFF, 1.00 2.00 3.00 4.00]NM
Trip is a section sailing distance that sailed from the point
“0” resets (*2) with 【 reset 】 key to present.
Temp. alarm・High (*3): When the set water temperature (warning value) is
exceeded, it generates an alarm.
Setting alarm value [OFF, 10 11 12 13 14 15 16 17] ℃
Wind speed alarm・Low (*3): When falling below the set the wind speed (warning value),
it generates an alarm.
Setting alarm value [OFF, 4.0 5.0 6.0 8.0 10.0 12.0 14.0]m/s
Stop of alarm buzzer
The corresponding measurement alarm is displayed when it reaches the set warning value,
and the alarm buzzer rings.
Stop the buzzer pushing the [BUZZER] key when the alarm buzzer rings.
Fig. 4.1.3 Ex.: Current speed alarm
Note: When the alarm buzzer rings, the operations of
the key other than [BUZZER] become invalid. Cancel
an alarm first pushing the [BUZZER] key when the
operations other than an OFF buzzer are done.
Afterwards, the measurement alarm buzzer will be
released in about five seconds automatically.
・Function・ Water temperature setting (*3): The water temperature graph is on current 1 screen,
current 2 screen, and the elapsed screen.
The setting of the graph sets width and the center (median) in the water temperature graph
together.
Operation Standard Menu: [MENU] key/Menu screen/Measure setting≫ /[ENT] key/Alarm and
Graph setting ≫/[ENT] key/ “Alarm and Graph setting” menu/Temperature graph center
and Temperature graph width (*4)
Selection Frame Menu: [□] key/ Enclose “Water temperature” with the frame /[MENU]
key/”Water temperature alarm and graph” menu/ Temperature graph center and
Temperature graph width (*4)
Temp. graph center: The water temperature value of the graph
center is set.
Temp. graph width: The water temperature range value is set.
Temp. graph display time: The display time of each screen is set.
Curr1 Picture: 60min. Fixed
Graph Picture: It depends on the setting of Time Scale.
*1 Around 5m and 500m of depth might not be able to be measured according to the condition of sea.
The display depth value is a mean value of depth measured from the ultrasonic beam in four directions, and no depth value of
the right under. The depth value is a value from oscillator (supersonic wave transducer) roller end face of this device, and the
water line is not corrected.
*2 How to “0” reset trip/timer value: Refer to 4.1.7 “Trip/Timer”.
*3 When the water temperature and the wind speed alarm are displayed, it is necessary to connect each sensor.
*4 The graph can be erased by selecting OFF. To restart the water temperature graph on the graph screen, set excluding OFF
from standard menu or the selection frame menu of current 1 and 2 screens.
