1. Safety Information
The meter is completely portable, LCD, 3 1/2 digit clamp with insulation test
function (with option 500V insulation tester unit). It has been designed
according to IEC-1010 concerning electronic measuring instruments with an
overvoltage category (CAT II) and pollution 2 and safety requirements for
handheld current clamps for electrical measurement and test.
Follow all safety and operating instructions to ensure that the meter is used
safely and is kept in good condition.
1.1 Preliminary
l When using this meter, the user m ust observe all normal safety rules
concerning :
- Protection against the dangers of electronic current.
- Protection of the meter against misuse.
l 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 electronic ratings. Measuring leads must be in good
condition.
1.2 During Use
l Never exceed the protection limit values indicated in specifications for
each range of measurement.
l When the meter is linked to measurement circuit, do not touch unused
terminals.
l When the value scale to be measured is unknown beforehand, set the range
selector at the highest position.
l Before rotating the range selector to change function, disconnect test leads
from the circuit under test.
l 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 me ter.
l Never perform resistance measurements on live circuits.
l Always be careful when working with voltage above 60Vdc or 30V ac rms.
DCM266 GB2
l When the jaw are open and will be connected to the conductor under test,
your fingers must keep behind the barrier indicator.
l Never ground yourself when taking electrical measurements. Do not touch
exposed metal pipes, outlets, fixtures, etc. which might be at ground
potential. Keep your body isolated from ground by using dry clothing,
rubber shoes, or any approved insulating material.
