1. INTRODUCTION
This meter measures AC/DC Voltage, AC/DC Current, Resistance,
Capacitance, Frequency (electrical & electronic), Duty Cycle,Diode Test,
and Continuity. Proper use and care of this meter will provide many years
of reliable service.
2. SAFETY SYMBOLS
This symbol adjacent to another symbol, terminal or
operating device indicates that the operator must refer to an
explanation in the Operating Instructions to avoid personal
injury or damage to the meter.
This WARNING symbol indicates a potentially hazardous
situation, which if not avoided, could result in death or
serious injury.
This CAUTION symbol indicates a potentially hazardous
situation, which if not avoided, may result damage to the
product.
This symbol advises the user that the terminal(s) so marked
MAX
must not be connected to a circuit point at which the voltage
with respect to earth ground exceeds (in this case)
1000V
1000 VAC or VDC.
This symbol adjacent to one or more terminals identifies
them as being associated with ranges that may, in normal
use, be subjected to particularly hazardous voltages. For
maximum safety, the meter and its test leads should not be
handled when these terminals are energized.
This symbol indicates that a device is protected throughout
by double insulation or reinforced insulation.
PER IEC1010 OVERVOLTAGE INSTALLATION CATEGORY
OVERVOLTAGE CATEGORY I
Equipment of OVERVOLTAGE CATEGORY I is equipment for connection to
circuits in which measures are taken to limit the transient overvoltages to
an appropriate low level.
Note – Examples include protected electronic circuits.
OVERVOLTAGE CATEGORY II
Equipment of OVERVOLTAGE CATEGORY II is energy-consuming
equipment to be supplied from the fixed installation.
Note – Examples include household, office, and laboratory appliances.
OVERVOLTAGE CATEGORY III
Equipment of OVERVOLTAGE CATEGORY III is equipment in fixed
installations.
