The light emitted by a lamp varies with the square of the current, so there
may very well be variations in values during the test which the human eye
does not detect.
When measuring temperature choose the probe most suited for the case:
immersion, penetration or surface probes. It is sufficient to immerse the
probe in the liquid of which you want to measure the temperature or place
in contact with the surface; in the case of penetration probes, the tip of the
probe must penetrate the block in which the temperature is to be measu-
red.
METHOD OF USE
Although the probes are sturdy, they must be used with due care so as to
avoid spoiling, scoring or breaking the filters or diffusors. Do not use them
at temperatures higher than 50°C; be careful when there is a concentration
of luminous beams or arc lights.
- Do not use the probes in the presence of corrosive gases or liquids or
immerse them in liquids unless they are made for these purposes.
- Always use the most suitable probe for the measurement to be taken.
- Be careful with the range of use of the probe.
- Always clean the probes carefully after use.
- The instrument is resistant to water but it is not watertight, so if it should
fall into the water, take it out immediately and check that no water has
infiltrated.
