User Manual TMP50 Type K/J Thermometer Introduction Congratulations on your purchase of the Triplett TMP50 Type K/J Thermometer This meter. This single input contact thermometer offers fast response and laboratory accuracy and works with K-type or J-type thermocouples as temperature sensors and offers a 0.1 0C/0.1 0 F resolution.
Safety Do not operate the meter in environments where the following are present: explosive gases (or materials), combustible gases (or materials), steam, or dust. Please replace the battery immediately when the low battery symbol appears on the LCD. Do not touch the meter’s circuit board for any reason; static electricity or contamination could damage the sensitive components. This instrument was designed for pollution degree 2. Operation Altitude: Up to 2000m (7000’). Description 1.

This meter accepts a K/J-type thermocouple with spade lugs (subminiature type with one spade wider than the other).
2. 3. Press the C-F-K button to select the desired temperature unit of measure. A display icon will reflect the selection. Touch the object to be measured with the probe. Read the measured temperature on the display. Note: If the display indicates “OL” the temperature is outside the measurement range. The display shows "- - - -" when a thermocouple is not connected. MAX/MIN/AVG mode Press MAX/MIN to capture and step through the maximum (MAX), minimum (MIN) and average (AVG) temperature values.
Press and hold the SET button for 3 seconds to enter or exit the Setup mode. When the thermometer is in Setup mode, the display shows the SETUP display icon. Set Type J or K thermocouple 1. Press ▲ or ▼to scroll to the “TYPE” setting (shown on the bottom left of the display). 2. Press ENTER to choose the option. 3. Press ▼ to toggle between J and K. 4. Press and hold the SET button for 3 seconds to save the setting and return to normal mode.
2. 3. 4. 5. Place the thermocouple into the known, stable temperature environment (such as an ice bath or dry well calibrator). Allow the reading to stabilize. Use the arrow keys ▲ ▼ to scroll to the “T1” option and then press ENTER. Change the offset temperature reading (upper display) by pressing ▼until the desired temperature is reached. Press and hold the SET button for 3 seconds to return to normal mode. Replacing the Batteries 1. Switch OFF the thermometer. 2.
Specifications Temperature Range: K type thermocouples -200°C to 1372°C (-328°F to 2501°F) J type thermocouples -210°C to 1100°C (-346°F to 2012°F) Note that thermocouple wire may be insulated with materials that cannot withstand temperatures in the ranges listed above. Check that the thermocouples used are rated for the temperature measurements to be made. Temperature accuracy: T1 Above –100 °C (-148 °F) T1 Below –100 °C (-148 °F) ± [0.15%rgd+1°C (1.8°F)] ± [0.5%rgd+2°C (3.
