How is the slide rule used?

Using the slide rule A. General Calculation Functions 1) Multiplication Example: 12 × 15 Operation: Align “12” on the outer scale with “10” on the inner scale. Then, “15” on the inner scale corresponds to “18” on the outer scale. Take into account the position of the decimal point and add one zero to obtain 180.? Note that with the scales of this watch, the position of the decimal point cannot be obtained. 2) Division Example: 300 / 15 Operation: Align “30” on the outer scale with “15” on the inner scale. Then, “10” on the inner scale corresponds to “20” on the outer scale. Take into account the position of the decimal point to obtain 20. 3) Reading Ratios Example: 50 / 20 = 30 / x Operation: Align “50” on the outer scale with “20” on the inner scale. Then, “30” on the outer scale corresponds to “12” on the inner scale. At this point, the proportion for every value on the inner and outer scales is “50:20”. 4) Determining Square Root Example: Square root of 169 Operation: Turn the outer scale slowly and find a value that corresponds to both “16.9” on the outer scale and “10” on the inner scale. In this example, “16.9” on the outer scale corresponds to “13” on the inner scale, and “10” on the inner scale corresponds to “13” on the outer scale. Thus, the answer is 13. B. Navigation Calculato r for motor sports 1) Time required Example: Obtain the time required 55 kilometers per hour for 330 kilometers. Operation: Align “55” on the outer scale with the SPEED INDEX “▲” on the inner scale.? Then, “33” on the outer scale corresponds to “6:00” on the inner scale (time scale).? Thus, the time required is 6 hours. * It is calculable also as mile instead of kilometer. 2 ) Speed Example: Obtain the kilometers per hour for 120 kilometers with a time of 1 hour and 30 minutes. Operation: Align “12” on the outer scale with “1:30” on the inner scale (time scale).? Then, the SPEED INDEX “▲” on the inner scale corresponds to “80” on the outer scale.? Thus, the speed is 80 kilometers per hour. 3) Mileage Example: Obtain the mileage when the speed is 40 kilometers per hour and the running time is 1 hour and 30 minutes. Operation: Align “40” on the outer scale with the SPEED INDEX “▲” on the inner scale.? Then, “1:30” on the inner scale (time scale) corresponds to “60” on the outer scale.? Thus, the mileage is 60 kilometers. 4) Rate of fuel consumption Example: Obtain the rate of fuel consumption (liters / hour) when the running time is 5 hours and the fuel consumption is 35 liters. Operation: Align “35” on the outer scale with “5:00” on the inner scale (time scale).? Then, the SPEED INDEX “▲” on the inner scale corresponds to “70” on the outer scale.? Thus, the fuel consumption is 7 liters per hour. 5) Fuel consumption Example: Obtain the fuel consumption required for a running when the rate of fuel consumption is 6 liters per hour and the running time is 5 hours. Operation: Align “60” on the outer scale with the SPEED INDEX “▲” on the inner scale.? Then, “5:00” on the inner scale (time scale) corresponds to “30” on the outer scale.? Thus, the fuel consumption is 30 liters. 6) Estimated running time Example: Obtain the estimated running time when the rate of fuel consumption is 5 liters per hour and the running has 30 liters of fuel. Operation: Align “50” on the outer scale with the SPEED INDEX “▲” on the inner scale.? Then, “30” on the outer scale corresponds to “6:00” on the inner scale (time scale).? Thus, the estimated running time is 6 hours. C. Navigation Calculator for sky sports 1) Time required Example: Obtain the time required for the fight of an aircraft at 160 knots for 240 nautical miles. Operation: Align “16” on the outer scale with the SPEED INDEX “▲” on the inner scale.? Then, “24” on the outer scale corresponds to “1:30” on the inner scale (time scale).? Thus, the time required for the flight is 1 hours and 30 minutes. 2) Speed Example: Obtain the knots (air speed) for 250 nautical miles with a flight time of 1 hour and 40 minutes. Operation: Align “25” on the outer scale with “1:40” on the inner scale (time scale).? Then, the SPEED INDEX “▲” on the inner scale corresponds to “15” on the outer scale.? Thus, the air speed for the flight is 150 knots. 3) Flight distance Example: Obtain the air distance when the air speed is 180 knots and the flight time is 40 minutes. Operation: Align “18” on the outer scale with the SPEED INDEX “▲” on the inner scale.? Then, “40” on the inner scale corresponds to “12” on the outer scale.? Thus, the air distance of the flight is 120 nautical miles. 4) Rate of fuel consumption Example: Obtain the rate of fuel consumption (gallons / hour) when the flight time is 40 minutes and the fuel consumption is 140 gallons. Operation: Align “14” on the outer scale with “40” on the inner scale. Then, the SPEED INDEX “▲” on the inner scale corresponds to “21” on the outer scale.? Thus, the fuel consumption is 210 gallons per hour. 5) Fuel consumption Example: Obtain the fuel consumption required for a flight when the rate of fuel consumption is 240 gallons per hour and the flight time is 1 hours and 40 minutes. Operation: Align “24” on the outer scale with the SPEED INDEX “▲” on the inner scale.? Then, “1:40” on the inner scale (time scale) corresponds to “40” on the outer scale.? Thus, the fuel consumption is 400 gallons. 6) Estimated flight time Example: Obtain the estimated flight time when the rate of fuel consumption is 200 gallons per hour and the aircraft has 1400 gallons of fuel. Operation: Align “20” on the outer scale with the SPEED INDEX “▲” on the inner scale.? Then, “14” on the outer scale corresponds to “7:00” on the inner scale (time scale).? Thus, the estimated flight time is 7 hours. D. Conversion 1) Distance Example: Convert 45 miles into nautical miles and kilometers. Operation: Align “45” on the outer scale with STAT “▲” on the inner scale. Then, NAUT “▲” on the inner scale corresponds to about “39” nautical miles on the outer scale, and KM “▲” on the inner scale corresponds to about “72” km on the outer scale. 2) Weight Example: Convert 16.4 oil lbs. into and liters. Operation: Align “16.4” on the inner scale with OIL LBS “▲” on the outer scale.? Then, U.S. GAL “▲” on the outer scale corresponds to about “2.2” IMP. GAL “▲” on the outer scale corresponds to about“1.8” IMP. gallons on the inner scale, and LITERS “▲” on the outer scale corresponds to about “8.3” liters on the inner scale. 3) Volume Example: Convert 13.1 fuel lbs. into and liters.

GAL “▲” on the outer scale corresponds to about “1.8” IMP. gallons on the inner scale, and LITERS “▲” on the outer scale corresponds to about “8.3” liters on the inner scale. 4) Fuel Example: Convert 16.8 Operation: Align “16.8” on the inner scale with U.S. GAL “▲” on the outer scale.? Then, IMP. GAL “▲” on the outer scale corresponds to about “14” IMP. gallons on the inner scale, and LITERS “▲” on the outer scale corresponds to about “63.5” liters on the inner scale.

Why isn’t Nightly Recharge displayed (acquired)?

Nightly Recharge data is acquired when the conditions below have been satisfied.? ● Nightly Recharge Data Acquisition Conditions Nightly Recharge data is acquired when there have been two days of sleep measurement data within the past 28 days, plus measurement data for the night prior to acquisition.? At least three days of sleep measurement data are required.? ● For example, to obtain "Nightly Recharge" for 4/30, you need to have sleep measurement data for the night of 4/29 (the night before 4/30), plus sleep measurement data for any two days from 4/3 to 4/28. ● Sleep Measurement Data Acquisition Conditions ・The watch worn the same way as you do during activity measurement.? https://support.casio.com/global/en/wat/manual/3515_en/VPCVSYtgulxurw.html ・User-specified nighttime, bedtime, and rise time settings.? ・Sleep (from bedtime to wake up) of at least 4 hours.? ・Heart rate measurement turned on while sleeping.? ・Normal movement. Constantly moving or barely moving can make accurate data acquisition impossible.? ・Keeping the watch on your wrist. Wearing the watch only while sleeping and taking it off immediately after waking can make accurate data acquisition impossible.? Important! ● To improve sleep analysis accuracy, it takes about one to two hours after you wake up for sleep measurement results to be displayed by the watch.? ● Sleep measurement is based on body movements measured by the accelerometer and RRI (R-R interval) obtained from the heart rate sensor.?  Accurate RRI (R-R interval) is not possible if the watch shifts on your wrist while you are sleeping, or if the sleeve of your clothing gets between the heart rate sensor and your wrist.?  The main reason why sleep measurement results are not output is usually due to problems with how the watch is worn. If you wish to use the watch during sleep, try wearing it in the same way as you do while performing activity measurement.
