INSTRUCTION MANUAL
No. 7610-20 Aneroid Barometer
Thank you for purchasing the Aneroid Barometer
This product is designed to measure atmospheric pressure and temperature mounting it on a
wall. Pressure reads in hectopascal (hPa) and millimeter of mercury (mmHg), and
temperature reads in Celsius (°C).
Read this manual thoroughly before use and keep it in safe place for future references.

Precautions
(1) Care for installation
Do not use the instrument
in corrosive gas
in dusty environments
Do not place near air conditioner or in direct sunlight.
Do not mount on the wall where directly contacts with air circulation from outdoors.
For mounting the instrument, install vertically on a wall without vibration.
(2) Care for handling
After unpacked, it takes about 15 - 30 minutes to indicate accurate value.
Never disassemble the instrument or it will be the cause of trouble.
Never touch the sensor unit.
Do not drop the instrument or apply impact to it. Doing so may result in malfunction.
Install the instrument with care. This instrument uses a precise mechanism to transmit the
expansion and contraction of the aneroid bellows to the pointers. Rough treatment will
damage the mechanism.
The adjustment screw is used for the calibration with a standard barometer (Mercury
barometer) and the sea level correction. Otherwise, do not use this adjustment screw.
Never use it at a place subject to water splash.
Do not cover the instrument with vinyl sheet for the purpose of waterproof or like.
Accurate barometric pressure reading will not be obtained.
Operation ambient is 0 to 50°C. Use the instrument within this range.
