INTRODUCTION
This instrument is a portable 3½ digit, compact-sized digital thermometer designed to use external K type and J type thermocouples. It also has the feature that sensor offset can be adjusted for in the field. There are 2 inputs for miniature thermocouple connectors at the top of the instrument marked T1 and T2.
SAFETY INFORMATION
It is recommended that you read the safety and opera­tion instructions before using the thermometer.
To avoid electrical shock, do not use this instrument
when working voltages at the measurement surface
To avoid damage or burns, do not make temperature
measurement in microwave ovens.
Repeated sharp flexing can break the thermocouple
leads. To prolong lead life, avoid sharp bends in the
leads, especially near the connector.
WARNING
over 24V AC or DC.

Temperature Scale:
Celsius or Fahrenheit user-selectable.
Measurement Range:
K-Type -100°C to 1372°C, (-150°F to 1999°F) J-Type -100°C to 1200°C, (-150°F to 1999°F)
Resolution:
1 degree or 0.1 degree from -59.9 to 199.9 degree °C or °F (auto ranging).
Accuracy:
Accuracy is specified for operating temperatures over the range of 18°C to 28°C (64°F to 82°F), for 1 year, not including thermocouple error. ±(0.1% rdg + 1°C) on °C, ±(0.1% rdg + 2°F) on °F
Readings are displayed in either degrees Celsius(°C) or degrees Fahrenheit(°F). When the thermometer is turned on, it is set to the temperature scale that was in use when the thermometer was last turned off. To change the temperature scale, press the “°C/°F” button.

When HOLD mode is selected, the thermometer holds the present readings and stops all further measurements. Pressing the “HOLD” button again cancels HOLD mode, causing the thermometer to resume measurement.
5. “APO/TYPE” Button
Press “TYPE” button to select the type of thermocouple “K” or “J”. Make sure the proper type has been selected. Pressing and holding down “APO” button for 2 seconds will turn on or off the APO(Automatic Power Off) mode, and the APO annunciator will appear or disappear on the display. Power is automati
cally turned off if no button is
pressed for a period of time.
6. “MAX MIN” Button
Press “MAX MIN” button to enter the MAX MIN re­cording mode. Press “MAX MIN” button to cycle through the MAX, MIN, MAX-MIN readings. In this mode, press “HOLD” button to stop recording, all values are held, press again to resume measurement. In this mode, the APO function and other buttons are disabled, excluding “HOLD” and “
” buttons. To prevent accidental loss of MAX, MIN and MAX-MIN, this mode can only be cancelled by pressing and holding down the “MAX MIN” button for 2 seconds to exit and clear readings.
7. “CLR/READ” Button
Press “READ” button to enter READ Mode, the “READ” annunciator is displayed in the upper right corner. Press “”or “” button to review the recorded data. The LCD automatically alternates between the data and index. Press the “CLR” button and hold down for 2 seconds to clear the memory data.
8. “REC” Button
Up 125 data points can be recorded into memory. Press “REC” button once to record each data point. When the data is recorded, “REC” is displayed in the upper right corne

9. “T1 T2/T1-T2/ ” Button
Press “T1”, “T2”, “T1-T2” button to select input mode T1, T2 or T1-T2. The input selection indicates which input is selected for display, T1 thermocouple, T2 ther­mocouple or the differential between the two thermocou­ples (T1-T2).
ADJUST THERMOCOUPLE OFFSET
1. Insert the thermocouple into a known temperature (T) until the display stabilizes near the known temperature (T). example: ice point at 0°C or boiling water at 100°C
2. Press and hold the “ADJ/HOLD” button for 2 seconds until the display starts to blink.
3. Press “ ” or “ ” to adjust the displayed value.
4. It can be adjusted ±6°F (±3°C) from default. If you can not adjust your reading
to match the known tempera­ture (T), please check your T/C type. The meter may require calibration.
5. Press “ENTER” button to confirm.
