GENERAL INSTRUCTIONS

1.1. Precautions and safety measures

1.1.1. Before using

You have just acquired a DMM210 meter. Thank you for your
confidence. It measures AC/DC Voltage, AC/DC Current, Resistance,
Frequency (electrical & electronic), and tests diodes and Continuity. It
features a waterproof, rugged design for heavy duty use. Proper use
and care of this meter will provide many years of reliable service.This
multimeter complies with the IEC 61010-1 and IEC 61010-2-033
standards concerning electronic measurement instruments. For your
own safety and to prevent damage to the instrument, follow the
instructions in this manual.
Be careful to adhere to storage conditions.
This handheld autonomous instrument was designed for:
∗
Indoor use
∗
Use in pollution degree 2 environments
∗
In altitudes lower than 2,000 metres
∗
In temperatures ranging from 5°C to 40°C.
It can be used up to 1000 V on category III circuits, or 600 V on
∗
category IV circuits.
MEASUREMENT CATEGORIES (IEC 61010-2-033)
CAT II: MEASUREMENT CATEGORY II is applicable to test and
measuring circuits connected directly to utilization points (socket outlets
and similar points) of the low-voltage MAINS installation. This part of
the installation is expected to have a minimum of two levels of
overcurrent protective devices between the transformer and the
connecting points of the measuring circuit.
Example : measurements on MAINS CIRCUITS of household
appliances, portable tools and similar equipment.
CAT III: MEASUREMENT CATEGORY III is applicable to test and
measuring circuits connected to the distribution part of the building's
low-voltage MAINS installation. This part of the installation is expected
to have a minimum of one level of over-current protective devices
between the transformer and possible connecting points.
Example : measurements on distribution boards (including secondary
electricity meters), circuitbreakers, wiring, including cables, bus-bars,
junction boxes, switches, socket -outlets in the fixed installation, and
equipment for industrial use and some other equipment such as
stationary motors with permanent connection to the fixed installation.
CAT IV: MEASUREMENT CATEGORY IV is applicable to test and
measuring circuits connected at the source of the building's low-voltage
MAINS installation. This part of the installation could have no over-
current protective devices between the transformer and connecting
points of the measuring circuit.
