Casio 5450 User Manual

wrong with the sensor.
Barometer/Thermometer Mode and Altimeter Mode sensor operations are disabled whenever there is not enough battery power available to perform a sensor operation.
This is true regardless of the current battery level. In this case, ERR will appear on the display. This does not indicate malfunction, and sensor operation should resume once battery
voltage returns to its normal level.
If ERR keeps appearing during measurement, it could mean there is a problem with the applicable sensor.
Whenever you have a sensor malfunction, take the watch to your original dealer or nearest authorized CASIO distributor as soon as possible.
The pressure differential level indicator does not appear on the display when I enter the Barometer/Thermometer Mode.
This could indicate sensor error. Try using C to re-enter the Barometer/Thermometer Mode.
The pressure differential level indicator is not displayed when the displayed current barometric value is outside of the allowable measurement range (260 to 1,100 hPa).
World Time Mode
■ The time for my World Time City is off in the World Time Mode.
This could be due to incorrect switching between standard time and daylight saving time. See “To specify a standard time or daylight saving time (DST) for a city” (page E-43) for more
information.
Specifications
Accuracy at normal temperature: ±30 seconds a month
Digital Timekeeping: Hour, minutes, seconds, p.m. (P), month, day, day of the week

Calendar System: Full Auto-calendar pre-programmed from the year 2000 to 2099
Other: Home City code (can be assigned one of 48 city codes); Standard Time /Daylight Saving Time (summertime)
Analog Timekeeping: Hour, minutes (hand moves every 20 seconds)
Altimeter:
Measurement range: –700 to 10,000 m (or –2,300 to 32,800 ft.) without reference altitude
Display range: –10,000 to 10,000 m (or –32,800 to 32,800 ft.)
Negative values can be caused by readings produced based on a reference altitude or due to atmospheric conditions.
Display unit: 5 m (or 20 ft.)
Measurement Timing: 5-second interval for first 3 minutes followed by 2-minute interval for the next 10 hours
Other: Reference altitude setting
Barometer:
Measurement and display range:
260 to 1,100 hPa (or 7.65 to 32.45 inHg)
Display unit: 1 hPa (or 0.05 inHg)
Measurement Timing: 5-second interval for first 3 minutes followed by 2-minute the interval for the next 10 hours in the Barometer/Thermometer Mode
Other: Calibration; Pressure differential level indicator
Thermometer:
Measurement and display range: –10.0 to 60.0°C (or 14.0 to 140.0°F)
Display unit: 0.1°C (or 0.2°F)
Measurement Timing: 5-second interval for first 3 minutes followed by 2-minute interval for the next 10 hours
Other: Calibration

Values are guaranteed for a temperature range of –10°C to 40°C (14°F to 104°F).
Precision is lessened by strong impact to either the watch or the sensor, and by temperature extremes.
Temperature Sensor Precision:
±2°C (±3.6°F) in range of –10°C to 60°C (14.0°F to 140.0°F)
World Time: 48 cities (31 time zones)
Other: Daylight Saving Time/Standard Time
Stopwatch:
Measuring unit: 1/100 second
Measuring capacity: 23:59′ 59.99″
Measuring modes: Elapsed time, split time, two finishes
Countdown Timer:
Measuring unit: 1 second
Countdown start time setting range: 1 minute to 24 hours (1-hour increments and 1-minute increments)
Alarms: 5 Daily alarms; Hourly time signal
Illumination: EL (electro-luminescent panel); Selectable illumination duration (approximately 1 second or 3 seconds)
Other: Low-temperature resistance (–10°C/14°F); Button operation tone on/off
Battery: One lithium battery (Type: CR2016)
Approximate battery operating time: 3 years under the following conditions:
1 illumination operation (1.5 seconds) per day
10 seconds of alarm operation per day
10 hours of altimeter measurement, once per month
Frequent use of illumination runs down the battery.
