Notes
WARNING
Please observe the following information before using the in-
strument:
Do not operate the instrument in the proximity of electrical
|
welders, induction heaters and other electromagnetic fields.
After an abrupt temperature fluctuation, the instrument
|
should be allowed to adjust to the new temperature for
about 30 minutes before using it. This helps to stabilize the
IR sensor.
Do not expose the instrument to high temperatures for a
|
long period of time.
Avoid dusty and humid surroundings.
|
Measurement instruments and their accessories are not
|
toys. Children should never be allowed access to them!
In industrial institutions, you must follow the accident pre-
|
vention regulations for electrical facilities and equipment, as
established by your employer's liability insurance organiza-
tion.
Each time before use, inspect the instrument to ensure that
|
it is working faultlessly (for example, on known source of
voltage, known resistor, etc.).
Please observe the following five safety rules:
Disconnect.
1
Ensure that the instrument cannot be turned back on again.
2
Ensure isolation from the main supply voltage (check that
3
there is no voltage on both poles).
Earth and short-circuit.
4
Cover neighbouring parts that are under live electrical load.
