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

SAFETY NOTES

 Do not exceed the maximum allowable input range of any function.  Do not apply voltage to meter when resistance function is selected.  Set the function switch OFF when the meter is not in use.  Remove the battery if meter is to be stored for longer than 60 days.

WARNINGS

 Set function switch to the appropriate position before measuring.  When measuring volts do not switch to current/resistance modes.  Do not measure current on a circuit whose voltage exceeds 600V.  When changing ranges, always disconnect the test leads from the circuit under test.

CAUTIONS

 Improper use of this meter can cause damage, shock, injury or death. Read and understand

this user manual before operating the meter.

 Always remove the test leads before replacing the battery or fuses.  Inspect the condition of the test leads and the meter itself for any damage before operating the

meter. Repair or replace any damage before use.

 Use great care when making measurements if the voltages are greater than 25VAC rms or

35VDC. These voltages are considered a shock hazard.

 Always discharge capacitors and remove power from the device under test before performing

Diode, Resistance or Continuity tests.

 Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty

of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not "live".

 If the equipment is used in a manner not specified by the manufacturer, the protection provided

by the equipment may be impaired.

 This device is not a toy and must not reach children’s hands. It contains hazardous objects as

well as small parts that the children could swallow. In case a child swallows any of them, please contact a physician immediately

 Do not leave batteries and packing material lying around unattended; they can be dangerous

for children if they use them as toys

 Expired or damaged batteries can cause cauterization on contact with the skin. Always,

therefore, use suitable hand gloves in such cases

 Do not short-circuited the battery. Do not throw batteries into a fire.
