INSTRUMENT OPERATION - Unscrew the battery cover and insert battery supplied.
The instrument will display '- -' and perform a self-test before measuring the ambient
temperature and humidity. For the most accurate recording of ambient temperatures, the
therma-hygrometer unit should be positioned away from direct sunlight and draughts. The
humidity reading is given in %rh (percentage relative humidity). This unit can be turned on
or off by pressing the button on the front of the unit.
MAX/MIN - Press the MAX/MIN button to display the maximum reading (MAX symbol
displayed). Press the MAX/MIN button again to display the minimum reading (MIN symbol
displayed). Press MAX/MIN button again to return to normal readings. Hold MAX/MIN for
three seconds to reset minimum and maximum temperature memory.
Please note: Max/Min readings are not saved so switching the thermometer off will clear
the max/min readings.
BATTERY REPLACEMENT - Replace the battery when the display dims, using a CR2032
battery. The battery is located in the battery cover at the rear of the instrument.
EMC/RFI - Instrument performance may be affected if operated within a high frequency
radio eld, such as near a mobile phone, or if subjected to an electrostatic shock.
