Hand Home Position Adjustment; Taking Temperature Readings; Temperature Sensor Calibration; Specifying Temperature Unit - Casio 5418 Operation Manual

Note
• While the 12-hour format is selected for timekeeping, a P (PM) indicator will appear for times from
noon to 11:59 p.m. No indicator appears for times from midnight to 11:59 a.m. With 24-hour format,
time is displayed from 0:00 to 23:59, without any P (PM) indicator.
• The watch's built-in full automatic calendar makes allowances for different month lengths and leap
years. Once you set the date, there should be no reason to change it except after you have the
watch's battery replaced.
• The day of the week changes automatically when the date changes.
E-16
• The dial hand must point to 12 o'clock.
• The watch will return to regular timekeeping automatically if you do not perform any operation for
about two or three minutes. Any changes you have made to settings up to that point will be saved.
2. Use D (+) and B (–) to adjust the position of the currently selected hand.
• Holding down either button will cause the hand to move at high speed. Once started, high-speed
hand movement will continue even if you release the button. To stop high-speed hand movement,
press any button.
• The second hand and dial hand will automatically stop high-speed movement after they complete
one revolution. The minute hand will stop automatically after 12 revolutions.
3. Press A to exit home position correction and return to regular timekeeping.
Note
• After performing home position adjustment, enter the Timekeeping Mode and check to make sure that
the analog hands and the lower display indicate the same time. If they do not, perform home position
adjustment again.

Temperature
• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to - - - °C (or °F) if a
measured temperature falls outside the range of –10.0°C to 60.0°C
(14.0°F to 140.0°F). The temperature value will reappear as soon as
the measured temperature is within the allowable range.

Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See "To specify
the temperature unit" (page E-22).

Temperature Sensor Calibration

The temperature sensor built into the watch is calibrated at the factory and normally require no further
adjustment. If you notice serious errors in the temperature readings produced by the watch, you can
calibrate the sensor to correct the errors.
Important!
• Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
– Compare the readings produced by the watch with those of another reliable and accurate thermometer.
– If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the
temperature of the watch time to stabilize.

Specifying Temperature Unit

Use the procedure below to specify the temperature unit to be used in the Thermometer Mode.
Important!
When TOKYO is selected as the Home City, the temperature unit is set
automatically to Celsius (°C). This setting cannot be changed.
To specify the temperature unit
1. In the Timekeeping Mode, press D to enter the Thermometer Mode.
2. Hold down A for about two seconds until the temperature reading
disappears from the lower display. Release A at this time, which will
cause the temperature reading to fl ash, which indicates the setting
mode.
3. Press C to display the current temperature unit in the lower display.
4. Press D to toggle the temperature unit between °C (Celsius) and °F
(Fahrenheit).
5. After the setting is the way you want, press A to exit the setting
screen.

Hand Home Position Adjustment

Strong magnetism or impact can cause the hands of the watch to be off.
• Home position adjustment is not necessary when the analog time and digital time are the same time in
the Timekeeping Mode.
To adjust home positions
1. In the Timekeeping Mode, hold down A and keep it depressed for
Dial hand Dial hand
about fi ve seconds until H.SET appears on the upper display.
When you release A after H.SET appears, the second hand will
•
move to 12 o'clock. This indicates the second hand home position
adjustment mode.
• Though ADJ will appear in the upper display about two seconds
after you hold down A, do not release the button yet. Keep it
depressed until H.SET appears.
Use the C button to select a hand for adjustment. Each press of
•
C cycles in sequences from the second hand, to the hour and
minute hands, and then the dial hand. Selecting a hand causes it
to move to 12 o'clock and the content of the lower display changes
as shown in the table below.
Lower display Selected hand
Flashing 00 Second hand
Flashing 0:00 Hour and minute hands
Flashing SUB Dial hand
• If the selected hand does not move exactly to 12 o'clock, perform step 2 below to adjust it.

Taking Temperature Readings

This watch uses a temperature sensor to measure temperature.
To take temperature readings
1. While in the Timekeeping Mode, press D to enter the Thermometer
Mode.
• TEMP will appear in the upper display and temperature
measurement will start. After about one second, the measurement
reading will appear in the lower display.
• The watch will continue to take temperature readings every fi ve
Temperature Temperature
seconds for one or two minutes.
2. Press D to return to the Timekeeping Mode.
• The watch will return to the Timekeeping Mode automatically if you
do not perform any operation for about one or two minutes after
entering the Thermometer Mode.
To calibrate the temperature sensor
1. Take a reading with another measurement device to determine the
exact current temperature.
2. With the watch in the Timekeeping Mode, press D to enter the
Thermometer Mode.
3. Hold down A for about two seconds until the temperature reading
disappears from the lower display. Release A at this time, which will
cause the temperature reading to fl ash, which indicates the setting
mode.
4. Use D (+) and B (−) to calibrate the temperature value with the reading of another instrument.
• Each press of a button changes the temperature value in units of 0.1°C (0.2°F).
To return the currently fl ashing value to its initial factory default setting, press D and B at the
•
same time.
5. Press A to return to the Thermometer Mode.
Thermometer Precautions
Temperature measurements are affected by your body temperature (while you are wearing the watch),
direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch
from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the
case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding
temperature.

Using the Stopwatch

The stopwatch measures elapsed time, split times, and two fi nishes.
To enter the Stopwatch Mode
Use C to select the Stopwatch Mode as shown on page E-8.
