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 or current
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 with CAT
IV 600V and CAT III 1000V.
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 4-20mA% display AC TRMS Current Resistance and Continuity test Diode test Capacity Current and voltage frequency Duty Cycle Temperature with K-type probe
Each of these functions can be selected by means of the appropriate switch. The instrument is also equipped with function keys (see § 4.2), an analogue bargraph and backlight. The instrument is also equipped with an Auto Power OFF function (which can be disabled), which automatically switches off the instrument 15 minutes after the last time a function key was pressed or the rotary switch was turned. To switch on the instrument again, turn the rotary switch.
2.1. MEASURING AVERAGE VALUES ANDTRMS VALUES
Measuring instruments of alternating quantities are divided into two big families: AVERAGE-VALUE meters: instruments measuring the value of the sole wave at
fundamental frequency (50 or 60 Hz).
TRMS (True Root Mean Square) VALUE meters: instruments measuring the TRMS
value of the quantity being tested. With a perfectly sinusoidal wave, the two families of instruments provide identical results. With distorted waves, instead, the readings shall differ. Average-value meters provide the RMS value of the sole fundamental wave; TRSM meters, instead, provide the RMS value of the whole wave, including harmonics (within the instruments bandwidth). Therefore, by measuring the same quantity with instruments from both families, the values obtained are identical only if the wave is perfectly sinusoidal. In case it is distorted, TRMS meters shall provide higher values than the values read by average-value meters.
2.2. DEFINITION OF TRUE ROOT MEAN SQUARE VALUE AND CREST FACTOR
The root mean square value of current is defined as follows: In a time equal to a period, an alternating current with a root mean square value of 1A intensity, circulating on a resistor, dissipates the same energy that, during the same time, would be dissipated by a direct current with an intensity of 1A". This definition results in the numeric expression:
G=
Tt
t
dttg
T
0

)(

2
The root mean square value is indicated with the acronym RMS.
The Crest Factor is defined as the relationship between the Peak Value of a signal and its RMS value: CF (G)=
RMS
p
G
G
This value changes with the signal waveform, for a purely
sinusoidal wave it is
2
=1.41. In case of distortion, the Crest Factor takes higher values
as wave distortion increases.
