ETI 810-180 Operating Instructions

Therma-Hygrometer
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
field, such as near a mobile phone, or if subjected to an electrostatic shock.

components or workmanship. During this period, products that prove to be defective will, at
the discretion of ETI, be either repaired or replaced without charge. The product guarantee
does not cover damage caused by fair wear and tear, abnormal storage conditions, incorrect
