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 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.
Definition of Installation categories (cf. IEC 664-1)
CAT I: Circuits protected by devices designed to minimize transient
overvoltage at a low level.
E.g. protected electronic circuits.
CAT II: Domestic or analogue appliances' power supply circuits that
can include average value transient overvoltage.
E.g. power supply to domestic appliances and portable tools.
CAT III: Power appliances' supply circuits that may include high
transient overvoltage.
E.g. machinery or industrial apparatus power supply.
CAT IV: Circuits that can include very high transient overvoltage.
E.g. energy inputs
For safety reasons, you should only use leads and measurement
accessories suitable for use with the voltage and overvoltage category
of the circuit to be measured that comply with the IEC 61010 standard.
The probes used for network voltage measurement must have an
assigned measurement category IV according to IEC 61010-031 and a
rated voltage of 600 V.
Do not use the instrument or its leads if they appear damaged.
