User manual CITIZEN CT830

[. . . ] There are separate collection systems for used electronics products in accordance with legislation under the WEEE Directive (Directive 2002/96/EC), effective only within European Union. - Eng 2 - Caution 1. The body temperature measured in the ear may differ from measurements taken under the armpits, in the mouth, or in the rectum. Take temperature readings periodically to determine the normal ear temperature measurement with this instrument, then use that reading as the basis for comparison with any measurement taken when you suspect a fever. Room temperature and material surface temperature readings are approximate and are only for reference. [. . . ] After the probe is positioned in the ear, press and hold the SCAN button until you hear one beep. Remove the probe and read the temperature on the display (Fig. 8). (Ear temperature mark) Fig. 8 NOTE: The time and calendar settings should be done before measurement readings are taken. The thermometer always shuts off automatically in about one minute and the stand-by mode display (room temperature and date/time) will be shown. Without the time and calendar settings, the display will not show any indications after the thermometer shuts off. Pressing the buttons will NOT shut off the thermometer. ROOM TEMPERATURE = STAND-BY MODE 1. Then the stand-by mode display will appear after the automatic shut-off. When in stand-by mode, the room temperature will always appear on the display with the icon (Fig. 9). (Room temperature mark) Fig. 9 - Eng 6 - MATERIAL SURFACE TEMPERATURE / STOP WATCH 1. MATERIAL SURFACE TEMPERATURE: Press and hold the ON/MEM button and then press the SCAN button once to leave the EAR EMPERATURE mode and enter the MATERIAL SURFACE TEMPERATURE scan icon (Fig. 10). mode with (Material surface temperature mark) Fig. 10 3. 1 Aim the probe torward the material and press the SCAN button, and the material surface temperature appears on the display. If the SCAN button is pressed and held, the measurement reading will be continuously updated. 3. 2 Applications include temperature measurements for water, milk, cloth, etc. Press and hold the ON/MEM button and then press the SCAN button once to leave MATERIAL SURFACE TEMPERATURE mode and enter the STOPWATCH mode with the icon (Fig. 11). NOTE: * Do NOT submerge the probe tip in liquid. * This mode shows the surface temperature of material only and is NOT for taking human body temperature. - Eng 7 - English 3. After measuring body or material surface temperature, the sensor may be warm which may affect the room temperature reading. Therefore during the first 15 minutes after every use, the room temperature on the display may be inaccurate. 4. STOP WATCH: English (Stop watch mark) Fig. 11 4. 1 This mode counts from 0. 01sec to 3 minutes. To reset the counter, press the ON/MEM button. Press and hold the ON/MEM button and then press the SCAN button once to leave STOP WATCH mode and return to the EAR TEMPERATURE mode. FEVER ALARM If the thermometer detects a temperature over 37. 5°C in the EAR TEMPERATURE mode, there will be a long beep followed by three short beeps to warn the user of a fever. MEMORY There are a total of 9 memory slots for recording EAR TEMPERATURE measurements. Memory slots can be cycled by pressing the ON/MEM button during the EAR TEMPERATURE mode (Fig. 12). (Memory mark) Fig. 12 NOTE: Even when a Memory slot is being displayed, users can measure ear temperature. CELSIUS/FAHRENHEIT OPTION SWITCH 1. Make sure the thermometer is in stand-by mode and indicating the room temperature, date, and time. Press and hold the SCAN button, then immediately press the ON/MEM button. (use same procedure to switch back to °C). - Eng 8 - AUTO POWER OFF FUNCTION If this unit is left unattended for about 1 minute, it will automatically power down from the current mode and enter the stand-by mode, showing room temperature, time, and date. [. . . ] Display: 3 digits with decimal point Battery mark Ear temperature mode Material surface temperature mode Stopwatch Memory °C or °F Battery: One lithium cell battery (CR2032 X 1 pc) Battery life: 3000 consecutive measurements or 1 year with 1-2 measurements per day including stand-by mode.
