Measurement 2/2: configuration of the measurement parameters (cont'd)
: resistive power reference W
Adjustment of the reference resistance (ref) between 1and 10,000, for resistive power
measurements. The calculation performed is:
(measured voltage)2/ Ref (unit W)
(measured current)2x Ref (unit W)
Default value 50 .
CLAMP 1/1: Parameterizing of the clamp function
The function (y = Ax) enables the user, measuring a current with a
current clamp in:
-Volts x V/A
-Ampères 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).
MATH: Parameterizing of the MATH function
The function (y = Ax + B) enables the user, measuring any physical
quantity in:
-Volts (process 0-10V or high-voltage probe, for example)
-Ampères (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).

Description of the "Keypad" keys4.2.
4.2.1. HOLD key: Management and hold of the display
Three operating modes are possible:
-the RUN mode HOLD inactive
-the HOLD mode [F2]
-the AUTO HOLD mode [F3]
The HOLD mode freezes the screen with the main measurement in progress
and the history curve as they were when the HOLD key was pressed. The instrument
continues to manage the measurements on the secondary display unit (REL mode).
The type of range selection remains the same: AUTO or MANUAL depending
on the configuration when this mode was entered.
The curve resumes at zero when RUN is pressed.
The AUTO HOLD mode automatically freezes on the screen the main
measurement in progress each time a stable measurement is detected. It is confirmed
by the emission of an audible beep (if the "No beep" configuration was not selected in
the Configuration menu).
The stored values remain displayed until the next stable measurement is made
(measurement different by ±100 digits) or until the AUTO HOLD mode is exited by
RUN.
The instrument continues to manage the measurements and to display them in the
graphic window or on the secondary display unit (REL mode).
The type of range selection remains the same (in AUTO or MANUAL)
depending on the configuration when this mode was entered. The AUTO HOLD mode
is available only for V and A measurements.
4.2.2. MEAS key: Advanced measurements

18
MEAS 1/3
3 levels of advanced measurements are possible
: selects graphic display of the screen for the quantity measured vs time.
The arrows can be used to change the depth of acquisition of the graph, from
1mn28s to 1h13mn20s. A search for the min and max of the main measurement is
made for the duration represented by one pixel horizontally. These two values are used to
trace a vertical segment from the min to the max. The keys can be used to change the
measurement range.
: takes the main measurement in progress as reference. It is transcribed
on the secondary display unit: REF.
-The main display continues to indicate the instantaneous measured value, as does
the bargraph.
-The secondary display indicates the absolute difference between the
instantaneous measured value and the recorded reference.
-The % secondary display indicates the relative difference in % between the
instantaneous measured value and the recorded reference.
Management of the ranges is "AUTOmatic" or "MANUal" depending on the
configuration when the mode was entered.
The and % display units are managed in the same range.
In the "AUTO" mode, they cannot fall below the range of the reference when the REL mode
was entered.
E.g.: Measurement of a voltage of VDC with a reference set to x V:
When the mode is active, a long press on key [F1] Init or [F2] Enter Ref opens a window for
setting reference REF.The navigation keys are used to modify the digits.
Reset of REF by a long press on Meas …
: monitors the variations of a signal, recording the extremes (MIN, MAX) of
the main measurement and calculating its mean (AVG).
For each quantity stored, the multimeter records the corresponding date and time.
When the SURV mode is entered by Start [F1], the last MIN and MAX
measurements are erased, then initialized with the present measurement; to stop this
mode, press [F2] stop; [F3] to look up.
AVG is the calculated mean of all measurements made since the activation of the SURV
mode.
The recorded data can be looked up by pressing Look up key [F3].
In the SURV mode:
-management of the MANU or AUTO range management cannot be selected.
-the present measurement, the MIN value, and the MAX value are presented in
the ranges best suited to each of them.
The recorded data are accompanied by the date and time, along with the surveillance
range.
Please update your multimeter before starting a SURVeillance campaign
(automatic synchronization).

MEAS 2/3
: directly displays the tolerance of the measurement in progress; there
is no need to search for it and calculate it.
From the main measurement, the display:
-recalls the specifications (x% L ±n D) according to the type of measurement,
the range selected and the frequency (in AC and AC+DC)
-calculates the range in which the true value lies, if the device is within its
tolerance:
SMIN value minimum specification
SMAX value maximum specification
: gives access to the secondary measurements.
Choice of secondary functions on display units 2, 3, and 4 by selection using the
navigator, according to the main measurement, and validation by OK.
A long press on MEAS… is used to exit from this menu.
When a main measurement is chosen, the last secondary functions selected
are reactivated.
Opposite, example of measurements available in VAC+DC.
When dB measurements are activated,the value currently measured is taken as
reference voltage (V ref). The calculation is as follows:
20 log10 (V measured / V ref).
The reference voltage (V ref) can be reset by a long press on Meas…
The MATH function is displayed when its parameters allow (see the MATH Function
menu).
For dBm measurements and resistive power calculations, refer to the menu for the
adjustment of the associated reference resistances (dBm REF, W REF) and the
calculation formulas. See SETUP 2/3.
The power calculation VxA(VA) requires a third connection on the A input (connected to
the same circuit), in order to measure simultaneously:
-the voltage (main display unit)
-the current (display unit 3), measurement always made in AC+DC.
The link to the COM input must be short and of large diameter, in order to limit the
voltage drop, which influences the Volt measurement.

MEAS 3/3
: The WFORM mode is available only in AC, for frequencies between 10
and 600Hz. It is used to display waveforms. When the frequency does not lie within the
measurement interval, or cannot be measured, the multimeter indicates "Frequency out of
bounds…". In the other failure cases, the multimeter indicates "Automatic adjustment
failed".
With weak signals, it may be necessary to change to MANUAL mode to reach the
most sensitive ranges using the keys.
4.2.3. Mem key: storage of the measurements, recording mode
The MEM mode records the content of the digital display(s) in the memory of the
device at a pre-programmed rate.
A short press on starts a recording series.
The MEM symbol is displayed in yellow during the whole recording period; it is
accompanied by the number of records made.
Another short press on stops the storage of the measurements and
displays the file name entry menu.
Pressing OK or Cancel without entering a name assigns the default file name
YYYYMMDD_HHMMSS.
The number of values to be stored for a measurement campaign can be
programmed: recording then stops automatically.
The records and the configuration can be looked up by a long press on
Another press on recalls a series of records.
Recording capacity 30 000
