True RMS Digital Multimeter
1 Safety information
This multimeter has been designed according to IEC - 1010 concerning
electronic measuring instruments with an overvoltage category (CAT II) and
pollution 2.
Follow all safety and operating instructions to ensure that the meter is used
safely and is kept in good operating condition.
1.1 Preliminary
•
When using the meter, the user must observe all normal safety rules
concerning :
- Protection against the dangers of electrical current.
- Protection of the meter against misuse.
•
Full compliance with safety standards can be guaranteed only if used with
test leads supplied. If necessary, they must be replaced with the same model
or same electric ratings. Measuring leads must be in good condition.
1.2 During use
•
Never exceed the protection limit values indicated in specifications for each
range of measurement.
•
When the meter is linked to a measurement circuit, do not touch unused
terminals.
•
When the value scale to be measured is unknown beforehand, set the range
selector at the highest position.
•
Before rotating the range selector to change functions, disconnect test leads
from the circuit under test.
•
When carrying out measurements on TV or switching power circuits, always
remember that there may be high amplitude voltage pulses at test points
which can damage the meter.
•
Never perform resistance measurements on live circuits.
