SPER800005-01 MAY.1999 I. Introduction: This instrument is a digital thermometer for use with any K-type and J-type thermocouple as temperature sensor. Temperature indication follows National Bureau of Standards and IEC584 temperature/voltage table for K-type and J-type thermocouples. II. Specifications: Numerical Display: 4 digital liquid crystal display Measurement Range: K-Type -200• ~ 1370• -328• ~ 2498• J-Type -200• ~ 760• -328• ~ 1400• Resolution: K-Type: -200°C~ 800°C 0.
Accuracy: at ( 23 ± 5°C ) Range Accuracy K-Type -200°C ~ 1370°C J-Type -200°C ~ 760°C K-Type -328°F ~ 2498°F J-Type -328°F ~ 1400°F ±(0.1% reading + 0.7°C) ±(0.1% reading + 0.7°C) ±(0.1% reading + 1.4°F) ±(0.1% reading + 1.4°F) Temperature Coefficient: For ambient temperatures from 0°C ~ 18°C and 28°C ~ 50°C, for each °C ambient below 18°C or above 28°C add the following tolerance into the accuracy spec. 0.01% of reading + 0.03°C ( 0.01% of reading + 0.
Battery Life: Approx. 100hrs with alkaline battery AC Adapter: 9VDC ±15% 100mA Plug Diameter: 3.5×1.35mm III. Symbol Definition and Button Location: Main Display H Timer Display : This indicates that the minus temperature is sensed. : It indicates that the timer is expressing in hours and minutes. °C °F : Centigrade and Fahrenheit indication. KJ HOLD : Thermocouple Type Indication : This indicates that the display data is being hold.
•REL : The reading is now under Relative Mode. : The Battery is not sufficient for proper operation.
Tripod connector 1•2 Battery cabinet cover 1 •1 IV. Operation Instructions: 4.1 Power-Up Press the •I key to turn the thermometer On or OFF 4.2 Connection the Thermocouples For measurement, plug the thermocouple into the input connectors. 4.3 Selecting the Temperature Scale When the meter was first power on, the default scale setting is set at Celsius (°C) scale. The user may change it to Fahrenheit (°F) by pressing “ °C/°F ” button and vice versa to Celsius. 4.
When the counting exceed 59min 59sec, the time scale will be changed to hours and minutes and the “ H ” symbol will appear on the display. The counting can be reset by press and hold “ TIMER ” button for 2 sec. 4.7 Relative Operation: When one press the “•REL” button, the meter will memorize the present reading and the difference between the new reading and the memorized data will be shown on the display. Press the “•REL” button again to exit the Relative operation. 4.
and “ °C/°F ” are disabled. To exit the MAX/MIN mode, one may press and hold for two seconds. 4.9 Auto Power Off: By default, when the meter is powered on, it is under auto power off mode. The meter will power itself off after30 minutes if no key operation and RS232 communication. Key combination at power on or RS232 communication can disable auto power off. One may press and hold “HOLD” button and then power on the meter and there will be two successive beeps to indicate that auto power off is disabled.
