Overview
This Operating Manual covers information on
safety and cautions. Please read the relevant
information carefully and observe all the Warnings
and Notes strictly.
In the event you find any missing or damage,
please contact your dealer immediately.
Safety Information
This Meter complies with the standards IEC61010:
in pollution degree 2, overvoltage category (CAT.
III 1000V, CAT. IV 600V) and double insulation.
CAT III: Distribution level, fixed installation, with
smaller transient overvoltages than CAT. IV.
CAT IV: Primary supply level, overhead lines, cable
systems etc.
Use the meter only as specified in this operating
manual, otherwise the protection
provided by the meter may be impaired.
In this manual, a warning identifies conditions and
actions that pose hazards to the user, or may
damage the beter or the equipment under test.
A note identifies the information that user should
pay attention on.
International electrical symbols used on the
meter and in this operating manual are explained
on page 2.
Rules For Safe Operation
Digital multimeter KN 8058 is an auto ranging
multimeter. the enclosure structure design
adopted advanced “co-injection” tecchnique in
order to provide sufficient insulation.
The multimeter can measure AC/DC voltage
and current, resistance, diode, continuity
buzzer, capacitance, frequency, transistor, hFE
and EF function, in addition to the conventional
measuring functions there is data hold, relative
mode, low battery display, display backlight and
sleep mode.
