If you operate with Fast update rate, the sensor must be charged
approximately every 24 hours. Used with Normal or Slow
update rates, the operational life is approximately 75 or 150
hours respectively. The optimal sensor charging temperature is
from +10 to +25°C.
Note: Note that charging sensors at sub-zero temperatures can create
explosive gasses. Simrad AS assumes no liability for the
improper charging of sensors or the use of chargers not
specified in Simrad’s sensor charging documentation.
Numerical presentation
On the PI54 display, the depth is displayed in the numeric
display. The descending or ascending rate is shown in units per
minute supported by an arrow indicating the direction. In order
to monitor changes of depth as a function of time, the depth will
also be displayed in the graphic display showing both the
numeric value and a corresponding marker line for each sensor.
When the readings are stable, the digits are shown in black
colour. When the values are predicted, the digits are grey, and if
the contact is lost, the characters *.* * are shown in grey.
(A) = Sensor set up as sensor no.1.
(B) = Current depth.
(C) = Current rate of depth change.
The arrow indicates that the depth is
ascending.
(D) = Indicator, lit for every sensor
interrogation.
(E) = Graphic alarm
(F) = Sensor set up as sensor no.2.
(G) = Interference symbol.
(H) = Current rate of depth change.
The arrow indicates that the depth is
descending.
