5. OPERATION
WARNING
The measurement range is for thermometers only. Users should choose proper probe
types for different kinds of applications. Please make sure the target to be measured
will not exceed the temperature range of the probe to avoid permanent damage to the
thermocouple probe.
Caution: To avoid electric shock and thermometer damage, do not measure the live
circuit with the thermocouple probe voltage exceeding 24V AC RMS or 60V DC.
EMC/RFI: Readings may be affected if the unit is operated within radiofrequency
electromagnetic field strength of approximately 3 volts per meter, but the instrument's
performance will not be permanently affected.

5.4 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.
Error 5~9
, for all other error messages it is necessary to reset
the thermometer. To reset it, turn the instrument off, remove the
battery and wait for a minimum of one minute, reinsert the battery
and turn on. If the error message remains please contact the
Service Department for further assistance.
‘Hi’ or ’Lo’ is displayed when the temperature being
measured is outside of the measurement range.
Accuracy (Tobj=
15-35°C,Tamb=25°C)
Tobj=0~460°C: ±2.5% of reading or 2.5°C (4.5°F) whichever is
greater
Tobj=-50~0 °C: ±(2.5°C+0.05/°C)
The thermometer is a non-contact infrared thermometer, and always with Real-Time Maximum
(MAX) data.Please remember to keep away from children and don’t use it for safety related
applications.
