ThermoWorks MTC Operating Instructions

BATTERY REPLACEMENT
When the BATTERY LOW icon is displayed, the battery should be replaced immediately with a
CR2032 lithium cell. The battery is located under the twist cover at the rear of the thermometer.
Please note: It is important to turn the thermometer off before replacing the battery, otherwise
the thermometer may malfunction.
Dispose of used battery properly and keep away from children.

OPERATING INSTRUCTIONS
1. Information is displayed on the LCD through the following symbols:
A. Temperature reading
B. Minus sign (negative temperature)
C. Battery status
D. HOLD (automatic shutdown after 15 sec.)
E. Selected temperature scale (˚C or ˚F)
A
B
HOLD
C D E
2. Insert a probe in to the thermocouple socket
3. To turn the thermometer on, press the ON/HOLD button for
approximately one second.
3. To select the desired temperature scale (˚C or °F) press the ON/HOLD button until the LCD
displays HOLD. Press the ˚C /°F button to change temperature scales. Press ON/HOLD again
to release the hold.
˚C /°F can only be changed only when HOLD is displayed.
4. For best results allow up to 30 minutes for meter to stabilize to ambient temperatures.

CERTIFICATE OF CONFORMANCE
The manufacturer of this instrument has implemented a quality
assurance system under ISO 9001:2000 certified quality system
and fully follow ISO GUM (Guide to the Expression of Uncertainty
in Measurement) to evaluate the uncertainty of temperature and
resistance standards, guarantee performance as below:
Calibration Temperature Max Error
0°C ±1.0°C
200°C ±2.0°C
1000°C ±10.0°C
Note: Assume the operation ambient temperature under 23 ±3°C
Furthermore, we certify that this infrared thermometer has been
inspected and found to comply with published specifications. This
device has been calibrated by temperature standards that are traceable
to NIST (U.S. National Institute of Standards and Technology) or NML
National Measurement Laboratory) of Taiwan, and the calibration
procedure corresponds with generally accepted regulations and
standards. The uncertainties of the reference standards used are:
±0.5°C accuracy and ±0.05°C stability.

5. Position the tip of the thermocouple where you wish to measure the temperature. Wait until the
temperature has stabilized. Read the temperature from the display.
6. To retain the temperature in the display, press the ON/HOLD button. The last measured value
is displayed.
To save battery power the thermometer deactivates itself automatically after about 15 seconds in
the HOLD position, or after about 4 minutes in normal display mode.
CAUTION
To protect the thermometer please observe the following:
1. Keep the thermometer away from electrostatic discharge.
2. Avoid "Thermal shock" caused by large or abrupt ambient temperature changes. Allow 30
minutes for the thermometer to stabilize before use when exposed to quick ambient shifts.
3. Do not leave the thermometer on or near objects of high temperature.
4. To avoid electric shock and thermometer damage, do not measure live circuits where voltage
exceeds 24V AC RMS or 60V DC with the thermocouple probe.
5. Readings may be affected if the thermometer is operated within a radio frequency
electromagnetic field strength of approximately 3 volts per meter, but its performance will not
be permanently affected.
6. Keep out of reach of all children.
STORAGE & CLEANING
Clean the thermometer with a damp cloth. Do not use any solvents such as acetone as they
corrode the plastic. Isopropyl alcohol may be used to disinfect. Do not submerge any part of the
thermometer. The thermometer should be stored at room temperature between +15 to +30°C
(+59 to +86°F).

LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
Er2 is displayed when the thermometer is exposed to rapid changes in the ambient
temperature.
Er3 is displayed when the ambient temperature exceeds 0°C (32°F) or +50°C
(122°F). The thermometer should be allowed plenty of time (minimum 30 minutes) to
stabilize to the working/room temperature.
Er5–9 is displayed for all other error messages. Clear the error by resetting the
thermometer. To reset, turn the thermometer off, remove the battery and wait for a
minimum of one minute. Reinsert the battery and turn it on. If the error message
remains please contact ThermoWorks for further assistance.
Hi or Lo is displayed when the temperature being measured exceeds the
measurement range of the thermometer.
BATTERIES
The thermometer incorporates visual low battery indication as follows:
'Battery OK': 'Battery Low': battery 'Battery Exhausted':
measurements needs to be replaced; measurements are
