Safety Notes
These are a few common safety practices for those working around
temperature critical environments:
• Follow the manufacturer’s maintenance
procedures when servicing equipment
• Place ONLY thermocouples (type K,J,T or E) in
the DT301 and DT302 thermocouple ports
• Make sure your meter is set for the proper
thermocouple type you are using
• Be sure the thermocouple you use can withstand
the temperature extreme it may be exposed to in your service task
• Properly maintain your thermometer and calibrate
it regularly
