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:
CAUTION
xDo not carry out any measurements in case gas, explosive materials or
flammables are present, or in humid or dusty environments.
xDo 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.
xAvoid any contact with the circuit being measured if no measurements are
being carried out.
x
A
void contact with exposed metal parts, with unused measuring probes,
circuits, etc.
xPay special attention when measuring voltages higher than 20V, since a risk
of electrical shock exists
xKeep the instrument steady during any measuring operation.
xDo not carry out any measurements which exceed the working and storage
temperature ranges specified in § 7
xOnly the accessories provided together with the instrument will guarantee
safety standards. They must be used only if in good conditions and
replaced with identical models, when necessary.
xCheck that the battery is correctly inserted.
xCheck that the LCD display gives indications consistent with the function
selected.
xDo not direct the instrument at very high intensity radiation sources (e.g. the
sun) in order to prevent damaging the IR sensor.
xPrevent hits or strong vibrations in order to keep the instrument from
damage.
xWhen bringing the instrument from a cold to a hot environment, leave it on
long enough for condensation water to evaporate.
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.
High voltage danger: electrical shock hazard.
This symbol indicates that the clamp can operate on live conductors
Double-insulated meter
AC voltage or current
DC voltage or current
Connection to earth
This symbol on the display means that the instrument (ECLIPSE) is able to emit
a laser pointer in Class 2. Do not direct the radiation towards the eyes in
order to prevent physical damage to people.

1.1. PRELIMINARY INSTRUCTIONS
xThis instrument has been designed for use in environments of pollution degree 2.
xIt can be used for VOLTAGE and CURRENT measurements on installations with CAT
IV 600V and CAT III 1000V
xWe 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.
xIn 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.
xOnly 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.
xDo not test circuits exceeding the specified voltage limits.
xDo not perform any test under environmental conditions exceeding the limits indicated
in § 0
xCheck that the battery is correctly inserted.
xMake 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.
xBefore activating the rotary switch, disconnect the test leads from the circuit being
measured.
xWhen the instrument is connected to the circuit being measured, do not touch any
unused terminal.
xDo not measure resistance in case external voltages are present; even if the
instrument is protected, an excessive voltage may cause malfunction.
xWhile 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
xWhen measurement is complete, set the rotary switch to OFF to switch off the
instrument.
xIf 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. § 6.7.4: Measured circuits, reads:
(OMISSIS)
Circuits are divided into the following measurement categories:
xMeasurement 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.
xMeasurement 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.
xMeasurement 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.
xMeasurement 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.

xIR sensor resolution: 80x80pxl
xBuilt-in laser pointer and illuminator
Each of these functions can be selected by means of the appropriate switch. The
instrument is also equipped with function keys (see § 4.2), analogue bargraph and LCD
TFT high-contrast color display. The instrument is also equipped with an Auto Power OFF
function which automatically switches off the instrument after a certain (programmable)
idling time.
2.1. MEASURING AVERAGE VALUES ANDTRMS VALUES
Measuring instruments of alternating quantities are divided into two big families:
xAVERAGE-VALUE meters: instruments measuring the value of the sole wave at
fundamental frequency (50 or 60 Hz).
xTRMS (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; TRMS 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.

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 § 8. In case of discrepancy, please contact the Dealer. In case
the instrument should be returned, please follow the instructions given in § 9
3.2. INSTRUMENT POWER SUPPLY
