3. OPERATING INSTRUCTIONS DIGITAL THERMOMETER Con oF OFFSET MO i THERMOMETER INTRODUCTION This instrument is a portable 31 2 digit compact sized digital thermometer designed to use external K type thermocouple as temperature sensor Temperature indication follows National Bureau of Standards and IEC 584 temperature voltage tables for K type thermocouples One K type thermocouple is sup plied with the thermometer SAFETY INFORMATION It is recommended that you read the safety and op eration instructions before using the thermometer Designed to meet IEC 1010 1 CE EMC WARNING TO AVOID ELECTRICAL SHOCK DO NOT USE THIS INSTRUMENT WHEN VOLTAGES AT THE MEASUREMENT SURFACE EXCEED 24V AC OR 60V DC WARNING TO AVOID DAMAGE OR BURNS DO NOT MAKE TEMPERATURE MEASUREMENTS IN MICRO WAVE OVENS CAUTION Repeated sharp flexing can break the thermocouple leads To prolong lead life avoid sharp bends in the leads especially near the connector The A symbol on the instrument indicates that the operator must refer to an explanation in this manual SPECIFICATIONS ELECTRICAL Temperature Scale Celsius or Fahrenheit user selectable Measurement Range i 50 C to 1300 C 58 F to 2000 F Resolution 1 C or 1 F 0 1 C or 0 1 F Accuracy Accuracy is specified for operating temperatures over the
4. eit 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 or F key Selecting the Display Resolution The thermometer allows two choices of resolution High resolution 0 1 C or 0 1 F Low resolution 1 0 C or 1 0 F To select the alternate display resolution press the corresponding 1 or 0 1 key The 0 1 resolution is applicable for temperature measurements below 200 C or 200 F HOLD Mode Pressing the HOLD key to enter the Data Hold mode the HOLD annunciator is displayed When HOLD mode is selected the thermometer holds the present readings and stops all further measurements Pressing the HOLD key again cancels HOLD mode causing the thermometer to resume taking measurements MIN MAX Mode Press MIN MAX once to begin recording MIN and MAX Press MIN MAX to select MIN or MAX Hold down for 2 seconds to exit MIN MAX function OFFSET ADJUSTMENT The OFFSET control is set at the factory to allow for the variations found in standard thermocouples By adjusting the OFFSET control you can optimize measurement accuracy for a particular thermocouple at a particular temperature Adjusting for Accurate Measurements 1 Connect the thermocouple to the input connector and turn the thermometer ON then press the 0 1 key to select the high display resolution 2 Place the th
