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 symbol ▲with the utmost attention.

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

• Do not carry out any measurement in humid environments.
• Do not carry out any measurements in case gas, explosive materials or flammables are present, or in dusty environments.
• Avoid any contact with the circuit being measured if no measurements are being carried out.
• Avoid any 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.
• Pay special attention when measuring voltages higher than 20V, since a risk of electrical shock exists.

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

Warning: observe the instructions given in this manual; improper use could damage the instrument or its components.

1.1. PRELIMINARY INSTRUCTIONS

• This instrument has been designed for use in environments of pollution degree 2.
• It can be used for VOLTAGE and CURRENT measurements on installations in CAT III 600V.
• We recommend following the normal safety rules devised by the procedures for carrying out operations on live systems and using the prescribed PPE to protect the user against dangerous currents and the instrument against incorrect use.
• In case the lack of indication of the presence of voltage may represent a danger for the operator, always carry out a continuity measurement before carrying out the measurement on the live system, in order to confirm the correct connection and condition of the leads.
• Only the leads supplied with the instrument guarantee compliance with the safety standards. They must be in good conditions and be replaced with identical models, when necessary.
• Do not test circuits exceeding the specified voltage limits.
• Do not perform any test under environmental conditions exceeding the limits indicated in § 6.2.1.
• Check that the battery is correctly inserted.
• Make sure that the LCD display and the rotary switch indicate the same function.

1.2. DURING USE

Please carefully read the following recommendations and instructions:

CAUTION

Failure to comply with the caution notes and/or instructions may damage the instrument and/or its components or be a source of danger for the operator.

• Before activating the rotary switch, disconnect the test leads from the circuit being measured.
• When the instrument is connected to the circuit being measured, do not touch any unused terminal.
• Do not measure resistance in case external voltages are present; even if the instrument is protected, an excessive voltage may cause malfunction.
• 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, set the rotary switch to OFF to turn off the instrument.
• If the instrument is not to be used for a long time, remove the batteries.

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. § 6.7.4: Measured circuits, reads:

(OMISSIS)

Circuits are divided into the following measurement categories:

• Measurement category IV is for measurements performed at the source of the low-voltage 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 inside buildings.

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

The instrument carries out the following measurements:

• DC voltage
• AC TRMS voltage
