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
1. ALWAYS turn the function switch to the OFF position when the meter
is not in use.
2. If “OL” appears in the display during a measurement, the value
exceeds the range you have selected. Change to a higher range.
NOTE: On some low AC and DC voltage ranges, with the test leads not
connected to a device, the display may show a random, changing
reading. This is normal and is caused by the high-input sensitivity. The
reading will stabilize and give a proper measurement when connected
to a circuit.
DC Voltage Measurements
WARNING: Risk of electrocution. High-voltage circuits, both
AC and DC, are very dangerous and should be measured with great
care.
CAUTION: Do not measure DC voltages if a motor on the
circuit is being switched ON or OFF. Large voltage surges may
occur that can damage the meter.
