AUTONAUTIC INSTRUMENTAL B175D Nautical Barometer
Boremeter Advice For Use
A barometer is an instrument used to predict a change in weather by measuring
variations in atmospheric pressure, or the weight of the air around us.
The barometer will normally indicate changes in weather 12 to 24 hours in
advance. It’s not an indicator of present weather conditions.
THE BAROMETER MUST BE ADJUSTED TO THE ALTITUDE OF ITS PLACE OF USE.
This is done by comparing it with a “master” barometer through the local
weather station, or the registered weather service by phone.
Don’t forget to consider the difference of altitu-de between the place of
adjustment and the place of use of your barometer:
10m more=1.1 hPa less!
Make this adjustment immediately after consul-ting the “master “barometer.
To make the adjustment, using a flat b l ade screwdriver, turn the adjustment
screw at the back side of the barometer.
WARNING: DO NOT OVERTIGHTEN THE ADJUSTMENT SCREW
QUARTZ CLOCK INSTRUCTIONS
Battery
- Use only alkaline batteries.
2.- If clock stops, it is most likely due a dead battery
3.- If clock is to be left unattended for a long
period of time. The battery should be removed. Otherwise it could become dead and
leak acid causing damage to the movement.
Note: Movement damage caused by battery leakage will void warranty
THERMOMETER & HYGROMETER INSTRUCTIONS
Thermometer operating instructions
A bimetal thermometer works on the principle that a different metals contract
and expand to different degrees when exposed to temperature changes
- Range: -20-50 º C/ -4-122 º F
- Tolerance: +/- 2ºC
Note: The Thermometer had been pre-adjusted and calibrated in a
temperature-controlled environment at factory.
Warning: The thermometer will be damaged if overtopping the working
range.
Hygrometer operating instructions
The hygrometer will indicate the relative humidity of the atmosphere. While
indoor and outdoor barometric is identical, it is not true of the relative
humidity. Therefore, remember that this instrument when used in the home
indicates humidity of the room atmosphere which has no relation to the outdoor
humidity readings announced on weather reports.
- Range: -20- 90 ºC % RH
- Tolerance: – 9ºC
Readjustment of the Hygrometer
If a hygrometer is exposed to very dry air over a longer period of time and if
you would like to maintain a correct reading, we recommend you to readjust the
instrument every 3-4 months.
Put a damp cloth on the back of the hygrometer for about an hour to allow
humidity to get into the instrument and circulate within the case of the
hygrometer. After that period of time the scale should read approximately 95%.
The humidity indicator will then start to operate again. To maintain accuracy
of this instrument, it is advisable to repeat this procedure every 3-4 months.
COMFORTMETER INSTRUCTIONS
This comfort meter is a combination of both temperature and humidity
indicators. Calibration and positioning of hands are designed to indica-te
perfect comfort conditions when both hands cross in a limited area of the
dial, the COMFORT zone.
Note: Both temperature and humidity indicators are accurately calibrated
at the factory and normally required no adjustment.
