Frequently Asked Questions - CM4281 ClimeMET

How do I set up the ClimeMET CM4281 weather station?

Insert 2 AA batteries into the main unit and the outdoor sensor. Place the sensor outdoors in a shaded location. The units will sync automatically within a few minutes.

What is the wireless range of the outdoor sensor?

The wireless range is up to 30 meters in open area. Walls and obstacles may reduce the range.

How do I change the batteries?

Open the battery compartment on the back of the main unit and the sensor. Replace with 2 new AA batteries each. Reinsert and close the cover.

Why is the outdoor temperature not showing?

Check that the sensor batteries are fresh and within range. Press and hold the 'CH' button on the main unit to rescan for the sensor.

Can I mount the weather station on a wall?

Yes, the main unit has a wall mount hole on the back. Use a screw (not included) to hang it securely.

How accurate is the temperature reading?

Temperature accuracy is typically ±1°C for indoor and ±2°C for outdoor readings under normal conditions.

Does the device show barometric pressure?

Yes, it displays barometric pressure and uses it to generate a weather forecast (sunny, cloudy, rainy, etc.).

How do I set the alarm?

Press the 'ALARM' button to enter alarm mode. Use the '+' and '-' buttons to set the desired time. Press 'ALARM' again to confirm.

What should I do if the display is dim?

Replace the batteries in the main unit. If still dim, the LCD may be defective; contact ClimeMET support.

Can I add extra sensors to the CM4281?

This model supports only one outdoor sensor. Additional sensors are not compatible.

Banjo Barometers

by ClimeMET

Banjo Barometer

Welcome to your ClimeMET Gainsborough Barometer, designed by a team of outdoor enthusiasts in rural Suffolk.

Let us help you make the most of the great outdoors.

Our ClimeMET Banjo Barometer is designed to provide temperature, humidity and pressure readings in one place, perfect for those who love being outside. For optimum results, it is necessary to calibrate the barometer part of the banjo to your local barometric pressure before use. The barometer is designed to give accurate air pressure readings from sea level to an altitude of 7000 feet.

Features

Measurement range: Temperature -40 to 50°C; -40 to 120°F. Humidity 0-100% RH. Pressure 720-795 mmHg; 960-1060 hPa.

Accuracy

Temperature: +/- 2°C

Relative humidity 0-45%: +/- 9% RH

Relative humidity 45-75%: +/- 6% RH

Relative humidity 75-100%: +/- 9% RH

Barometric pressure 960-990 hPa: +/- 10 hPa

Barometric pressure 990-1030 hPa: +/- 5 hPa

Barometric pressure 1030-1060 hPa: +/- 10 hPa

Location

Position your banjo barometer in an area where it can remain undisturbed. Do not position in direct sunlight and avoid sources of heat and humidity that are not representative of the area you are looking to measure, such as a kettle.

Setting Up Your Banjo Barometer

• Establish the current pressure for your location by visiting www.bbc.co.uk/weather.
• Adjust the needle via the turn screw on the back of the dial to set the current barometric pressure. Do not over-tighten the barometer movement as this can damage the mechanism.
• Hang the banjo barometer in your desired location using the keyhole fitting on the back and leave for a few days to acclimatise.

Reading Your Banjo Barometer

• Increasing pressure (movement of the needle in a clockwise direction) suggests improving weather.
• Decreasing pressure (movement of the needle in an anti-clockwise direction) suggests deteriorating weather.
• Steady pressure, typical of extended periods of fine weather, suggests more of the same conditions.
• Use the left-hand side of the stick thermometer scale to read current air temperature in ^ C and the right-hand side for ^ F.
• Use the hygrometer scale to read current humidity in % RH.

Using The Pressure Pointer

The settable pointer, controlled by the knob in the centre of the barometer dial face, can be used to show changes in atmospheric pressure. To do this, move your settable pointer until it rests exactly over the internal needle. The next time you observe your dial, any change in pressure will be highlighted by looking at the difference in position of the two pointers.

All wooden weather instruments are suitable for indoor use only.
