Measurement Category Application
I
Measurements on circuits not directly connected to mains.
Examples include: Measurements on battery powered
equipment and specially protected (internal) mains-derived
circuits.
II
Measurements on circuits directly connected to the low
voltage installation.
Examples include: Household appliances, portable tools and
similar equipment.
III
Measurements performed in the building installation.
Examples include measurements on distribution boards,
junction boxes, socket-outlets and wiring and cables in the
fixed installation.
IV
Measurements performed at the source of the low-voltage
installation.
Examples include measurements on primary overcurrent
protection devices and electricity Instruments
OPERATION
AC/DC Voltage measurements
CAUTION:
Do not measure AC/ DC voltages if a motor on the circuit is being
switched ON or OFF. Large voltage surges may occur that can damage the meter.
1. Set the function switch to the green V position.
2. Press the MODE button to indicate “DC” or “AC” on the display.
3. Touch the black test probe tip to the negative side of the circuit.
Touch the red test probe tip to the positive side of the circuit.
4. Read the voltage in the display
DC/AC Current measurements
1. Set the function switch to the μA/mA position.
2. For current measurements up to 4000μA DC/AC, set the function switch to the mA
position
3. Press the MODE button to indicate “DC” / “AC” on the display.
4. Remove power from the circuit under test, then open up the circuit at the point where
you wish to measure current.
5. Touch the black test probe tip to the negative side of the circuit.
Touch the red test probe tip to the positive side of the circuit.
6. Apply power to the circuit.
7. Read the current in the display
NOTE:
200mA/600V fast acting Resettable Fuse current inputs and Overload protection
on mA, μA ranges. No replacement required.
