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
