During Use - Metrix OX 530 Manual De Funcionamiento

Chapter II
- This instrument was designed for use indoors in an environment with a degree of
pollution 2 at an elevation of less than 2000 m, a temperature between 0°C and 40°C,
and a relative humidity of 80 % up to 31°C.
- It can be used for measurements on 300 V, installation category II.
- Definition of installation categories (see publication IEC 664-1):
CAT I :
CAT II :
CAT III :
CAT IV :
- Check that your electricity distribution network is within the range 105 to 240 V.
- Earth all metallic parts that are accessible to touch (including the working table).
- The three-phase network power supply cable (phase, neutral and earth) delivered with
the apparatus is conform with IEC standard 61010 1993, + A2 1995. Check that it is in
perfect working condition before use.
- Plug the cable into a socket fitted with an earth connection.

1.1.2. During use

- For your own safety, only use the cables, measurement probes and appropriate
accessories delivered with the apparatus or approved by the manufacturer as optional
accessories.
- Select vertical sensitivity and timebase ranges adapted to the measurement or use the
AUTOSET.
- Never touch an unused terminal when the apparatus is connected to measurement
circuits.
- Carefully read all notes preceded by the
30 MHz oscilloscope
CAT I circuits are protected by devices limiting transient overvoltages to a
low level.
Example: protected electronic circuits
CAT II circuits are power supply circuits for domestic or digital devices that
may include transient overvoltages with an average value.
Example: power supply for household appliances and portable tools.
CAT III circuits are power supply circuits for power equipment that may
include large transient overvoltages.
Example: power supply for industrial machines or equipment
CAT IV circuits may include very high transient overvoltages.
Example: energy arrivals
