Entering/Converting Time Values
NautiCalc Plus recognizes two distinct time values:
1. Points in Time: 9:22 AM, 5 PM
2. Time Periods: 37 Min., 45 Sec.
Time Math Rules Addition
Period + Period = Period
3 Hrs. + 22 Min. = 3
HR 22 MIN
Point + Period = Point
9 AM + 22 Min. = 9:22 AM
Point + Point = Error
Subtraction
Period – Period = Period
3 Hrs. – 22 Min. = 2
HR 38 MIN
Point – Period = Point
9 AM – 22 Min. = 8:38
AM
Point – Point = Period
9 AM – 8:30 AM = 30
MIN
Note: When subtracting one point in time
from another, enter the later time first then subtract the earlier time.

Distance and Speed Calculations
The NautiCalc Plus can perform math functions using units of speed and dis­tance. Some points to remember while performing these calculations are:
1) When adding a list of numbers with the same unit designator (i.e., miles), only the first value entered requires a designator. The same is true when subtracting two numbers.
2) Mixing speed and distance units will result in an error due to the difference in dimensions. For example, you can­not mix knots and miles; knots is a speed and miles is a distance.
3) Conversion can only be performed within the same types of dimensions. For example, hours can be converted to minutes, minutes to seconds, etc.

Using the Triangulation Function
Triangulation solutions are easy when using NautiCalc Plus. By entering your course, bearings and the distance traveled between bearings, you can determine the distance from the object and the distance Abeam.
Course and bearings 1 and 2 may be entered as either decimal degrees or as degree:minute:seconds. The value for “Course” can be entered by entering the value and pressing [Course°]. The value is permanent until revised or [Conv] [x] is pressed to perform an “All Clear.”
The distance from the bearing object can be found by pressing the [Dist] key twice

in succession. To find the distance Abeam, press [Dist] a third time.
Triangulation Example 1
Using a lighthouse for positioning, your bearings read 33.75° and 57.10°. If the ship traveled 10 nautical miles between bearing measurements on a 12°34’26” course, what is your distance from the lighthouse at the second bearing mea­surement? What is the distance Abeam?

Using the Stopwatch/Timer
NautiCalc Plus includes a stopwatch timer with buzzer and split/ lap functions. When activated, the timer can count up from zero or down from an entered time. The display accuracy can be set to show zero to two decimal points (00:00:00, 00:00:00.0, 00:00:00.00).
While the timer is counting, a clock symbol (❹) flashes at the bottom of the display. A star (.) symbol appears if the timer buzzer is set to “On.” Timer values can be used in calculations or stored in Memory.
Note: The display accuracy and timer buzzer can be set via the Preference function.
[Timer]
Displays, activates, and stops the timer. If a value is entered prior to activating the timer, the timer acts as a countdown timer.
[S/Lap]
Freezes the display. Once the display is frozen, the value displayed may be saved in Memory by pressing [Stor] then the register number. e.g., [Stor] 1.
Note: Pressing the [Off] key twice stops and exits the stopwatch timer. Press [On/C] to reset the display.

Split/Lap Function
Use the [Prefs] key to determine whether the [S/Lap] key acts like a split func­tion or a lap function.
If the “S/LP” preference is set to “Split,” the total time elapsed from the start of the timer to the moment the [S/Lap] key is pressed displays. If set to “Lap,” the time elapsed be-tween presses displays. For example, the first press of [S/Lap] displays the time elapsed from the timer’s start point to the time [S/Lap] is pressed. The second press of [S/Lap] continues the time display. A third press displays the time elapsed between the first and third presses. The fourth press continues the time display. The fifth press shows the time elapsed between the third and fifth press and so on. Even though the timer display is stopped, the timer continues to count. Therefore, if the second press occurred at 30 seconds, the display at the fourth press will show the cumulative value of 30 plus the time passed between the third and fourth presses.
Note: Every time the [S/Lap] key is pressed, the time elapsed is stored as a value in the paperless tape.

Accuracy/Display
Each calculation is carried out internal­ly to 10 digits and is rounded to an 8–digit standard display. A 5/4 round­ing technique is used to add 1 to the least significant digit in the display if the next non–displayed digit is 5 or more. If this digit is less than 5, no rounding occurs.
Errors
An error will occur:
1) when an incorrect entry is made.
2) if the answer is beyond the range of the calculator.
3) if you enter a mathematical impos­sibility such as division by zero.
To clear an error, press [On/C].
