It complies with safety standard NF EN 61010-1 + NF EN 61010-2-030
concerning electronic measuring instruments.
For best results, read this manual closely and observe the precautions of use.
Failure to observe these warnings and/or directions may damage the
instrument and/or its components and may endanger the user.
Precautions and
safety measures
This instrument is been designed to be used as follows:
- indoors
- in an environment of pollution degree 2
- at an altitude of less than 2000m
- at a temperature between 0°C and 40°C
- at a relative humidity below 80% up to 35°C.
The safety of any system incorporating the instrument is the responsibility
of the system integrator.
It can be used for measurements on 1000V circuits in CAT III and
600V circuits in CAT IV.
However, some accessories may lead to the use of this instrument on circuits
of a lower voltage and category.
before use
Comply with the environmental and storage conditions.
Check the integrity of the guards and insulation of the accessories. Any item
of which the insulation is deteriorated (even partially) must be removed from
service and scrapped. A change of colour of the insulation is a sign of
deterioration.
Supply: primary battery or Ni-MH battery and specific charger supplied with
the instrument. It must be connected to line power :
(230V ±10%, 300V - CAT II), (US version: 110V ±10%).
during use
Read closely all notes preceded by the symbol.
As a safety measure, use only the appropriate leads and accessories
supplied with the instrument or approved by the manufacturer.

General directions
Definitions of the
measurement
categories
CAT II: Test and measurement circuits directly connected to the points of use
of the low-voltage network (power outlets and other similar points).
E.g.: Measurements on the network circuits of household appliances, portable
tools, and similar devices.
CAT III: Test and measurement circuits connected to parts of the low-voltage
network of the building.
E.g.: Measurements on distribution panels (including secondary meters), circuitbreakers, wiring including cables, bus bars, branch boxes, disconnecting
switches, power outlets in the fixed installation, and industrial appliances and
other equipment, such as motors permanently connected to the fixed
installation.
CAT IV: Test and measurement circuits connected to the source of the lowvoltage network of the building.
E.g.: Measurements on devices installed before the main fuse or the circuitbreaker of the building installation.
Warning!
Using a measuring instrument, a lead, or an accessory belonging to a lower
measurement or voltage category derates the resulting system (instrument
+ leads + accessories) to the lowest measurement category and/or service
voltage of any of the components.

Getting started
Preparation for use
Instructions before
starting up
When you use this multimeter, you must observe the usual safety rules,
which:
protect you from electrical hazards,
protect the multimeter from operator errors.
For your safety, use only the leads supplied with the instrument.
Before each use, make sure that they are in perfect condition.
Power supply via the
charger
From 230V ±10% mains (US version: 110V ±10%) with the specific charger
delivered with the instrument (45 to 65 Hz).
The mains connector is on the side of the multimeter.
Powering up,
down
Press the key opposite, on the left front panel of the instrument, to switch it
on or off. A switching-off page reports the switching off of the active
multimeter.
Automatic current
measurement
detection
The number of input terminals is limited to 3: V, COM, A.
Connecting the lead to the "Ampere" terminal automatically selects the
corresponding function.
When a change of function from the control keypad is
incompatible with the connection of the lead, an audible and
visual alert is triggered (LEADS).
Automatic
power down
The current measurement is made in automatic range mode over the whole
span.
Validate the function by the Standby menu: the device stops automatically
after 30 minutes of operation if during this time there has been no action on
the front panel and if the multimeter remains immobile.
The device is switched back on by the key.
Automatic switching off is disabled in:
Surveillance mode SURV
Record mode MEM
Communication mode (isolated USB optical link, Bluetooth)
when the quantity measured (Voltage or Current) on the inputs of the
multimeter exceeds the danger threshold.
Alert signal
An intermittent audible signal is emitted:
* in the "Voltage" setting, when the range is exceeded
(MANUal and AUTO mode - last range)
* in the "Current" setting, when the range is exceeded
(MANUal mode), starting from a measurement of 10 Amperes
* when the connection of the leads is incompatible with the function
selected
* when the danger thresholds are exceeded (if the function is validated)
When the range is exceeded, the audible signal is accompanied by display
of the "O. L" acronym.
When the symbol is activated:
* the voltage on the "Volt" input exceeds 60 VDC or 25 VAC
* the current injected between the "Ampere" terminal and COM exceeds
10A
* the range (voltage or current) is exceeded in MANUAL mode

For your safety, automatic switching off is
disabled when the quantities measured (voltage,
current) on the input exceed the danger
thresholds.
Beep: validation (default) or not of the
emission of an audible signal (beep) when:
- a key is pressed,
- there is a voltage on the "V" input exceeding
605 VDC or 30 VAC,

The audible signal is maintained even
when the buzzer is deactivated:
- in a continuity test,
- when a range is exceeded (voltage or
current),
- for a measurement of 10A or more,
- when there is an incompatibility
between the connections of the leads
and the function selected
- when the supply voltage (battery) is
too low blinking of the red batt

2. Clamp
The CLAMP function (y = Ax) enables the
user, measuring a current with a current clamp
in:
- Volts x V/A
- Amperes x A/A
to assign the ratio (or transformation ratio) and
the appropriate unit, in order to obtain a direct
reading of the measured current.
Depending on the quantity measured, the
device calculates the function Ax associated
with it.
The programming is in 3 stages:
1. Selection of the quantity measured,
Measurement (V, A)
2. Definition of the ratio A displayed
on the clamp Val1/ Val2 or:
xxxx.XA/xxxx.XV
(default is 1A/1V)
3. Definition of the physical unit to be
displayed (default is A)
The ratio A and the unit can be
programmed for each quantity measured
(V, A).
3. Math
The MATH function (y = Ax + B) enables the
user, measuring any physical quantity in:
- Volts (process 0-10V or high-voltage probe,
for example)
- Amperes 4-20mA current loop or current
clamp, for example)
- Frequency (measurement of flow rates,
speeds of rotation, for example)
- Ohms (resistive position sensor, for
example)
to convert it and assign the appropriate unit, in
order to obtain a direct reading of the original
quantity on the instrument.
Depending on the quantity measured, the
device calculates the MATH function
associated with it.
The programming is in 4 stages:
1. Selection of the quantity measured
(V, A, ,Hz)
2. Definition of the coefficient A of the
function y = Ax + B
3. Definition of the coefficient B of the
function y = Ax + B
4. Definition of the physical unit to be
displayed by the navigator (Upper-case
and lower-case)
The coefficients A and B and the unit
can be programmed for each quantity
measured (V, A, , Hz).
