Care & Maintenance

Display Care
Clean with a soft, damp cloth. Do not use caustic cleaners or abrasives. Keep away from dust, dirt and moisture. Clean ventilation ports regularly with a gentle puff of air.
5-in-1 Sensor Care
Clean the Sensor
Clean with a soft damp cloth. Do not use caustic cleaners or abrasives that will mar the polished surfaces of the rain collection funnel or the solar cell. Scratches will result in decreased performance and reliability.
Insect Prevention
Insects may cause obstructions and interrupt data by nesting in or on the 5-in-1 sensor. To limit this problem, spray sensor with a household insect repellent. Consult the insect repellent instructions prior to use.
Snow & Freezing Weather
The 5-in-1 sensor will not be damaged by freezing conditions. NOTE: If the rain collector cup fills with snow and then melts, it will register as rain on the display.
Clean the Rain Collector Cup
Remove and empty rain collector debris filter. The debris filter is located in the rain collector funnel. Remove from the top by gently squeezing and pulling out.
Clean the Wind Vane & Anemometer
Remove foreign matter from the outside of the sensor for free movement of the wind vane and anemometer. If needed, use a small amount of spray lubricant, clear silicone or graphite powder on the anemometer for improved movement.
Calibration
The indoor / outdoor temperature and humidity readings, and barometric pressure can be calibrated on the display to improve accuracy. Calibration can improve accuracy when sensor placement or environmental factors impact the data accuracy.“

To access calibration mode, press AND HOLD the “”, “SET”, and “” buttons simultaneously for at least 5 seconds.
To adjust the currently selected (flashing) item, press and release the ““ or ““ buttons to calibrate the data value higher or lower from the actual reading.
To save your adjustments, press and release the “SET” button to adjust the next preference. The “” icon will remain illuminated next to calibrated values.
The preference set order is as follows:
- OUTDOOR TEMPERATURE
- OUTDOOR HUMIDITY
- INDOOR TEMPERATURE
- INDOOR HUMIDITY
- BAROMETRIC PRESSURE (must be set to MANUAL mode to calibrate)*

*To change from AUTO to MANUAL pressure mode and vice versa, press and HOLD the “SET” button for at least 10 seconds. The display indicates the current pressure mode selected,“AUTO” or “MANUAL”.

After 20 seconds of inactivity, the display will save the adjustments and exit calibration mode. Note: Calibrations will be erased if the display is reset or if batteries are removed and the power adapter is unplugged.

Calibrate the Rain Gauge

The rain gauge on the 5-in-1 sensor can be calibrated to improve accuracy.
Items Needed: 5-in-1 sensor, display unit, plastic cup, pin, screw driver

First, ensure 5-in-1 sensor is perfectly level using built-in bubble level.
Place display unit close so you can monitor it during calibration.
Make a pin hole in the bottom of a plastic cup. Hold the cup over the rain gauge and fill it with exactly 1 cup (8oz) of water, allowing the water to drip into the rain gauge. You should hear the internal buckets tip and see water drain through the rain gauge.
A few seconds after each bucket tip, the display unit displays rainfall in approximately 0.01” or more increments.
The cup of water should take more than 20 minutes to empty; a quicker period will result in inaccurate calibration. Try to simulate a normal steady rainfall. When cup is empty of water, display unit should register 1.06”

Tips

There should be nearly an equal number of water drops (about 25 water drops) between bucket tips. If not, adjust the calibration screws on the bottom of the 5-in-1 sensor until an equal number of water drops are tipping the buckets. Then, restart the calibration procedure.
If you don’t hear the buckets tipping and see water dripping alternately out of each drain, there may be an issue with the rain gauge or it’s adjustment.

Acurite Professional Weather Center 01531 Adjustment

If the rain gauge doesn’t register close to 1.06”, make an EQUAL adjustment to the two calibration screws on the bottom of the 5-in-1 sensor. Turning screws clockwise increases rainfall; counter clockwise decreases rainfall.

To adjust the rainfall reading by 2% turn both screws 1/8 of a turn.
To adjust the rainfall reading by 4% turn both screws 1/4 of a turn.
To adjust the rainfall reading by 8% turn both screws 1/2 of a turn.

Troubleshooting

Problem

Possible Solution

No outdoor sensor reception

no bars

Relocate the display and/or the 5-in-1 sensor.

The units must be within 330 ft (100 m) of each other.

Make sure both units are placed at least 3 feet
