This instrument is a 4½ digit, compact-sized portable digital thermometer designed to use external K-type and J-type thermocouples as temperature sensor. Temperature indication follows Reference Temperature/Voltage Tables (N.I.S.T. Monograph 175 Revised to ITS-90) for K-type and J-type thermo- couples. One K-type thermocouple are supplied with the thermometer.
ELECTRICAL Temperature Scale: Celsius or Fahrenheit user-selectable Measurement Range: J-TYPE -200°C to 1050°C, (-328°F to 1922°F) K-TYPE -200°C to 1370°C, (-328°F to 2498°F) Resolution: 0.1°C or 0.2°F 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. ±(0.05% rdg + 0.3°C) -50°C to 1370°C ±(0.05% rdg + 0.7°C) -50°C to -200°C ±(0.05% rdg + 0.6°F) -58°F to 2498°F...

OPERATOR MAINTENANCE WARNING To avoid possible electrical shock, disconnect the thermocouple connectors from the thermometer before removing the cover. Battery Replacement Power is supplied by a 9 volt "transistor" battery. The " " appears on the LCD display when replacement is needed. To replace the battery, remove the two screws from the back of the meter and lift off the battery cover.
CALIBRATION PROCEDURE Note: The following calibration procedures should be performed only by qualified technicians who have access to the following: Equipment: The class of calibration should be 10 times greater than the measured meter. Step 1: Short the J3 with jumper. Step 2: Apply 65 mV to the T1 input from Volts Calibrator and wait till the reading becomes stable, then press the SET key until the display shows 0.1.
