4. OPERATION INSTRUCTION
4.1 Preparation before measurement
4.1.1 Check the installation of the battery. If “ ” shows up, please replace it with a new battery.
4.1.2 Make sure the setting of function keys is correct. (HOLD symbol shouldn’t be shown on
LCD when taking measurements).
4.1.3 Pay attention to the polarity of the temperature input terminal. Make sure the “＋”“－”ends
of the thermocouple are inserted into the relative jack.
4.1.4 For obtaining an accurate measurement result, after you insert the thermocouple or change
thermocouple, please wait for 3 minutes to warm-up before taking measurements.
4.2 Measuring method
4.2.1 Panel descriptions:
① LCD: display digits, polarity symbol “-”, low battery indicator “ ”, and temperature unit ℃
and ℉.
② POWER: turn ON/OFF the thermometer.
③ HOLD: press HOLD button to hold the current
measurement value on the LCD for later check, and then
press HOLD button again to exit the hold mode.
④ ℃: choose ℃temperature mode
⑤ ℉: choose ℉temperature mode
⑥ 0.1℃/1℃: choose 0.1℃/1℃and 0.1℉/1℉resolution.
-50℃～199.9℃, 0.1℃
-50℉～199.9℉, 0.1℉
-50℃～1300℃, 1℃
-50℉～1999℉, 1℉
⑦ K-type thermocouple input terminal. Max. input voltage: DC 60V or AC 24V.
4.2.2 Operation steps:
4.2.2.1 Insert the thermocouple into the temperature input terminal.
4.2.2.2 Press Power key to turn on the meter and wait to warm-up for 3 minutes.
4.2.2.3 Select the function and range.
4.2.2.4 Apply the probe to the object under measuring.
4.2.2.5 Get the reading.
4.3 Thermocouple usage directions
4.3.1 When measure the internal temperature or the liquid temperature, for obtain accurate
measurement result, the insert depth should be 15-20 times of the diameter of the probe.
4.3.2 When measure the surface temperature, for obtain accurate measurement result, the top of the
probe should be clung to the surface under test.
5. MAINTENANCE
5.1 Do not expose the meter to the rapidly changed environment or environment with high
temperature, high humidity and high vibration
5.2 Remove the battery, if the thermometer will not be used for a long time.
5.3 Please use K-type thermocouple.
5.4 Do not use this meter for voltage and current measurement. To avoid damage, do not input voltage
higher than DC 60V or AC 24V.
5.5 The probe of thermocouple might be oxidized corroded or polluted, which will cause the aging of
the probe and affect the accuracy of measurement. So clean the probe frequently and change it if it
is corroded.
5.6 During measurement, do not expose the thermometer to the heat source directly. Make sure the
environment temperature for the thermometer isn’t beyond its working temperature.
5.7 The meter is a precise instrument. Random changes to the circuit are not allowed.
The specifications are subject to changes without prior notice.
