MARTEL 306 I. Introduction: This instrument is a digital thermometer for use with any K-type thermocouple as temperature sensor. Temperature indication follows National Bureau of Standards and IEC584 temperature/voltage table for K-type thermocouples. Its internal memory can store up to 16,312 records.(See Note 1 below.) An RS232 interface provides bi-directional communication with a PC. II.
MARTEL 306 III. Symbol Definition and Button Location: : This indicates that a negative temperature is sensed. ƨƩ K : Centigrade and Fahrenheit indication. : Thermocouple Type Indication MAX : The Maximum value is being displayed MIN : The Minimum value is being displayed : This indicates auto power off is enabled. : This indicates that the display data is being held.
MARTEL 306 IV. Operating Instructions: 4.1 Power-Up Press the power button to turn the thermometer ON or OFF. When powered on, the LCD will show how much memory space is available to use.
