1. Operation- Do not use this device near machines that emit strong electromagnetic
fields or objects that store static electricity.
- Do not drop or subject this device to strong impact.
- Do not use or store this device where it will be exposed to water or inplaces with wet conditions.
- Do not use or store this device where it can be exposed to direct sunlight,dust, high temperature and high humidity.
- See the battery case markings to ensure that the battery is properly installed.
- For accurate measurements, do not subject this device in measuring suddenchange of temperatures.
- Remove the battery when the device will not be used for a long period oftime.
- Do not attempt to disassemble or modify this device.

2. Thermocouple Probe- Do not measure beyond the temperature limits of the thermocouple probe
being used.
- Do not use thermocouple probe in places where presence of electric
shock is suspected.
- Avoid using the thermocouple probe to measure materials that may cause
rust or corrosion. If used, wipe the thermocouple probe with a dry clean
cloth after every use.
- Do not attempt to disassemble or bend the miniature connector of thethermocouple probe.
- Avoid bending, dropping or hitting the thermocouple probe, even when
not in use.
- When measuring surfaces, make sure that the thermocouple probe is incontact with the surface perpendicularly to record accurate measurements.
- In measuring surfaces of non-metallic materials, transfer of heat takes
longer than normal, therefore, make measurement time longer to get.
