1. PRECAUTIONS AND SAFETY MEASURES

The instrument has been designed in compliance with directive IEC/EN61010-1 relevant to electronic measuring instruments. For your safety and in order to prevent damaging the
instrument, please carefully follow the procedures described in this manual and read all notes preceded by the symbol with the utmost attention

Before and after carrying out the measurements, carefully observe the following instructions:

• Do not carry out any current measurement in humid environments.
• Do not carry out any measurements in case gas, explosive materials or flammables are present, or in dusty environments.
• Avoid contact with the circuit being measured if no measurements are being carried out.
• Avoid contact with exposed metal parts, with unused measuring probes, circuits, etc.
• Do not carry out any measurement in case you find anomalies in the instrument such as deformation, breaks, substance leaks, absence of display on the screen, etc.

In this manual, and on the instrument, the following symbols are used:

CAUTION: observe the instructions given in this manual; an improper use could damage the instrument or its components.
Double insulated meter.
AC current
DC voltage
Ground reference
Use appropriate security measures to apply/remove the instrument on/from live conductors

1.1. PRELIMINARY INSTRUCTIONS

• his clamp has been designed for use in environments of pollution degree 2.
• It can be used for AC CURRENT measurements, on installations with measurement category CAT IV 600V or CAT III 1000V refer to ground. For a definition of the abovementioned categories, see § 1.4
• This instrument is not suitable for direct current measurements
• Please take the standard safety precautions aimed at protect you against dangerous electric currents and protect the instrument against incorrect use
• Do not test circuits exceeding the specified current and voltage limits
• Check that the battery is correctly inserted

1.2. DURING USE

Please carefully read the following recommendations and instructions

• Before switching on the clamp, remove the conductor from the clamp jaw.
• During current measurement, any other current near the clamp may affect  measurement precision.
• When measuring current, always put the conductor as near as possible to the middle of the clamp jaw, as described in § 4.1.2 to obtain the most accurate reading.
• While measuring, if the value or the sign of the quantity being measured remain unchanged, check if the HOLD function is enabled.

1.3. AFTER USE

• When measurement is complete, switch off the clamp.
•  If the instrument is not to be used for a long time, remove the battery.

1.4. DEFINITION OF MEASUREMENT (OVERVOLTAGE) CATEGORY

Standard IEC/EN61010-1: Safety requirements for electrical equipment for measurement,control and laboratory use, Part 1: General requirements” defines what measurement category, commonly called overvoltage category, is. In § 6.7.4: Measured circuits, circuits are divided into the following measurement categories:

(OMISSIS)

• Measurement category IV is for measurements performed at the source of the lowvoltage installation.
  Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units.

•  Measurement category III is for measurements performed on installations insidebuildings.
  Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to fixed installation.

• Measurement category II is for measurements performed on circuits directly connected to the low-voltage installation.
  Examples are measurements on household appliances, portable tools and similar equipment.

• Measurement category I is for measurements performed on circuits not directly connected to MAINS.
  Examples are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS-derived circuits. In the latter case, transient stresses are variable; for that
  reason, the standard requires that the transient withstand capability of the equipment is made known to the user.

2. GENERAL DESCRIPTION
