Digital Thermometer

IMPORTANT SAFETY INFORMATION
Please read these instructions carefully before use and retain for future
reference.
• When using electrical appliances basic safety precautions should always be
followed.
• Before use, check that there is no damage to the instrument, there is no metal
exposed or sign of wear to the insulating layer of the probe.
• When the low battery indicator is displayed, replace the battery immediately to
avoid any potential measurement error.
• If the thermometer is not going to be used for a long period of time, remove the
batteries to avoid any potential product damage caused by battery leakage.
• The instrument is not suitable for fast measuring changes in ambient temperature.
• Do not allow the thermocouple probe to contact charged objects, otherwise it may
damage the instrument.
• Do not fold the thermocouple leads, as repeated bending over a period of time
may cause the wire to break.
OVERVIEW
1. Room temperature sensor
2. LCD
3. Data hold key
4. Slide switch
• OFF - Power off
• °C - Celsius display unit
• °F - Fahrenheit display unit
5. Range selection key: Range
switching 0.1 or 1 resolution
6. Thermocouple jack
7. K-type thermocouple probe
USAGE
• Insert the K-type thermocouple into the thermocouple jack.
• Move the slide switch to the “°C” or the “°F” position.
• Place the thermocouple probe in contact with the measured object.
• Read the results on the LCD.
• If the value displayed is less than 200, you can choose to display 0.1 range
resolution by pressing the “RANGE” button.
Note: When the thermocouple is not inserted into the thermocouple or the
thermocouple is open, the instrument will display the temperature of the environment.

CLEANING & MAINTENANCE
• Do not attempt to repair the instrument unless you are an experienced repair
person and have associated calibration, performance testing and maintenance
information.
• To clean the outer casing, use a clean, damp cloth and some mild detergent.
• Do not use any chemicals, abrasives or solvents that may damage the instrument.
REPLACING THE BATTERIES
• When the low battery indicator is displayed, replace the battery immediately to
avoid any potential measurement error.
• Turn off the power supply to the instrument.
• Loosen the screws of the battery cover and replace the battery cover.
• Remove the old batteries and replace with new ones.
• Replace the battery cover and tighten the screws so the cover is secure.
