Amprobe ACDC-620T, User Manual, Page: 7 / 65

● Set the proper function and renge before attaching the metr to circuit. To avoid
damaging the meter disconnect the test leads from test points before changing
functions.
● Read this operation manual completly before using the meter and follow all
safety instructions.
● The meter is safety-certified in compliance with UL3111-1, C22.2 NO.1010.1-
92 and EN61010(IEC 1010-1, 1010-2031,IEC 1010-2-32) Instalation Category
ll 1000V or instalation Category lll 600V. In order to mantain its insulation
properties, please be sure to use ULListed Category ll 1000V or Category lll
600V probes.
● insrtallation category (CAT) ll is an environment with smaller trasient overvolt-
age than Installation Category lll.
● CE requirement: Under the influence of R.F field according to standard, the
supplied test leads will pick up induced noice. To have better shielding tests
are required in order to conform to CE:
1. IEC 801-2: ESD (electro-static discharge) test.
2. IEC-801-3: RFI (Radio frequency Interference) test.
Condition : 27 ~ 500MHz, signal intensity is 3 volts per meter.
3. IEC 801-4: EFT(electro-fast transient) test.
4. EN 55011: EMI (electromagnetic interference) test.
● Do not allow the temperature sensor to contact a surface which is energized
above 30 V RMS or 60V DC, such voltages pose a shock hazard.
