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.
Double-insulated meter
AC voltage
DC voltage or current
Connection to earth
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
DC current
AC TRMS current
Resistance and Continuity test
Frequency
Duty Cycle
Diode test
Capacity
Each of these functions can be activated by means of the appropriate switch. The
instrument is also provided with a HOLD/ , MODE/ , RANGE and MAXMIN button. For
their use, please refer to § 4.2. The instrument is also equipped with a white light torch and
an Auto Power OFF function which automatically switches off the instrument 15 minutes
after the last time a function key was pressed or the rotary switch was turned.
3. PREPARATION FOR USE
3.1. INITIAL CHECKS
Before shipping, the instrument has been checked from an electric as well as mechanical
point of view. All possible precautions have been taken so that the instrument is delivered
undamaged.
However, we recommend generally checking the instrument in order to detect possible
damage suffered during transport. In case anomalies are found, immediately contact the
forwarding agent.
We also recommend checking that the packaging contains all components indicated in §
6.3.1. In case of discrepancy, please contact the Dealer.
In case the instrument should be returned, please follow the instructions given in § 7.
3.2. INSTRUMENT POWER SUPPLY
The instrument is supplied with 2x1.5V alkaline batteries type IEC AAA LR03, included in
the package. When the battery is flat, the symbol
“ ” appears on the display. To replace
the battery, see § 5.1.
3.3. CALIBRATION
The instrument has the technical specifications described in this manual. The instrument's
performance is guaranteed for one year.
3.4. STORAGE
In order to guarantee precise measurement, after a long storage time under extreme
environmental conditions, wait for the instrument to come back to normal condition (see §
6.2.1).
