4. Operation Instruction *NOTE: In order to ensure the accuracy of the measurement readings, all the interference sources which may affect the measurement results about temperature and humidity (such as the hand) must be clear from the sensor. 4.1. ON/OFF

1. First remove the meters protective sensor cover. 2. Press the ON/OFF key to turn the power ‘ON’. 3. The LCD will display the current value of humidity and temperature. Default setting is %RH/°C (humidity/temperature). 4. To turn the meter ‘off ’ press the ON/OFF key for 2 seconds. Note: The power to the meter will switch off automatically after 20 minutes but be aware that leaving the meter in for any length of time will drain the battery.

4.2. UNIT

1. When the meter is switched ‘on’ press the UNIT key to change through the 4 different humidity/temperature measurement options. 2. The available setting are as follows: %RH/°C, td°C/°C , %RH/°F, td°C/°F (%RH = Relative humidity / td°C = Dew-point temperature) 4.3. MODE

1. When the meter is switched ‘on’ and the required ‘UNIT’ (%RH/°C, td°C/°C , %RH/°F, td°C/°) has been selected press the MODE key to display the Maximum or Minimum readings, this is acknowledged with the symbol MAX or MIN on the LCD display. 2. To cancel the Maximum or Minimum readings press the MODE key until the symbols no longer appear on the LCD Screen.

4.4. HOLD/LIGHT

HOLD HOLD 1. Press the LIGHT key to freeze the reading shown, the LCD will display the H symbol. HOLD 2. Press the LIGHT key once more to cancel the hold function. The H symbol will disappear NOTE: As a safety feature, the meter will not turn ‘off’ if the HOLD function is activated.
