Precautions:
- Do not put sensor in the liquid or make the sensor exposed to sunlight;
- Do not put the instrument under extreme conditions or the heavily polluted environment such as chemical vapors, hazardous substances and so on, so as not to affect the accuracy of the meter, and even cause damage or reduce the life of the instrument;
- Do not use solvents and detergents to clean the product, and do not disassemble the body arbitrarily for research or repair;
- Remove the battery if do not use for a long time, so as to avoid battery leakage and corrosion of the instrument;
- When the battery is low (LCD displays the symbol of
), please replace the battery, so as not to affect test accuracy.
), please replace the battery, so as not to affect test accuracy.PANEL DESCIPTION
- Humidity / Air Temperature Probe: (Humidity Sensor and Semiconductor Sensor inside)
- LCD display: 4 1/2 dual digits LCD display with units of ‘C, “F, %RH dewpoint wet bulb and low battery “BAT” MIN /MAX HOLD, DATA HOLD indication.
- MAX/ MIN Button:MAX/MIN: Press MAX/MIN to enter MAX, MIN Recording mode (manual range only). Select the proper range before selecting MAX MIN to ensure that the MAX/MIN reading will not exceed the testing range. Press once to select MIN. Press again to select MAX. Press and hold the Button for over 2 second to tum off MAX. MIN Recording.

Humidity and air Temperature Measurements
- Hold the probe in the area to be tested & allow adequate time for readings to stabilize.
- Press °F, °C ,dewpoint, WBT select Button to enter select” °F, °C, dewpoint WBT Measurement.
- Read the Relative Humidity and Air Temperature, dewpoint temperature wet bulb temperature.NOTE: Do not immerse the probe in liquid,· it is intended for use in air on.
Warning:Don’t expose the humidity sensor to direct sunlight (insolation).Don’t touch or manipulate the humidity sensor.
Battery Replacement
If the sign “
” appears on the LCD display, it indicates that the battery should be replaced. Open the battery case and replace the exhausted battery with new battery. (1 x 9V battery NEDA 1604, 6F22 or equivalent)
