IntroductionThis meter measures AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency (electrical & electronic), Duty Cycle,

Diode Test, and Continuity plus Thermocouple Temperature. It features a waterproof, rugged design for heavy duty use. Proper use and care of

this meter will provide many years of reliable service.

Safety

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.

WARNING

This WARNING symbol indicates a potentially hazardous situation, which if not

avoided, could result in death or serious injury.

CAUTION

This CAUTION symbol indicates a potentially hazardous situation, which if not

avoided, may result damage to the product.

MAX

1000V

This symbol advises the user that the terminal(s) so marked must not be connected

to a circuit point at which the voltage with respect to earth ground exceeds (in this

case) 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.

Note – Examples include switches in the fixed installation and some equipment for industrial use

with permanent connection to the fixed installation.

OVERVOLTAGE CATEGORY IV

Equipment of OVERVOLTAGE CATEGORY IV is for use at the origin of the installation.

Note – Examples include electricity meters and primary over-current protection equipment
