a laboratory digital oscilloscope for the analysis of electronic and electrotechnical signals,
a 2-channel, 8000-count multimeter,
a harmonic analyser, for the simultaneous decomposition of 2 signals with their fundamental and their rst 31 harmonics.
The instrument operates at a constant acquisition depth of 2,500 points.
An LCD TFT screen is used to view the applied signals along with all the setting parameters.
The main command functions are accessible using the keys on the front panel.
A graphic interface is used to:
- adjust the parameters related to the selected button,
- navigate using a horizontal main menu showing the current settings and vertical sub-menus.
2.2. POWER SUPPLY
The oscilloscope is delivered with:
one mains to USB supply and one jack to USB cord with a ferrite
Voltage: 5 VDC
Power: 2 A
Polarity:
6 rechargeable NiMH (1.2 V - LR6 or AA) accumaltor batteries.
When the external power supply is connected, this power source is preferred for the instrument's operation. Thus the accumulators
are only used when there is no external power supply.
With the external power supply you can use your oscilloscope even if the batteries are at, defective or even
absent.
2.3. BATTERIES
A "battery empty" indicator appears on the screen when the accumulator-battery charge level is insu󰀩cient and
a new power source is needed quickly:
connect the external power supply or
change the batteries.
If the external power supplied is not connected when the level becomes critical, an alarm message "Battery level
is critical, the appliance is about to power o󰀨" precedes the automatic shutdown of the instrument.

8
2.3.1. CHARGE
The batteries are charged when the oscilloscope is powered o󰀨 but connected to the external power supply.
During the fast charge of the batteries, the front-panel LED is on.
It ashes in the following situations:
pre-charge of very at batteries
temperature too low or too high
batteries damaged.
The batteries must be replaced with rechargeable Ni-MH batteries. The life between charges will be the same as with the batteries
supplied with the oscilloscope if the replacement batteries have the same capacity (indicated in Ah).
The LED goes o󰀨 when charging is complete.
If charging is interrupted before it is complete, the LED remains on for one minute to remind the user that the batteries are not
fully charged.
It is possible, but not recommended, to use standard alkaline batteries (AA type) to replace the accumulators,
but in this case be careful:
not to connect the external power supply because when the instrument is switched o󰀨 the charge mechanism is activated
which can lead to destruction of the batteries and damage to the instrument;
not to leave the batteries in the instrument for too long to avoid any problems caused by leakage from the batteries.
2.3.2. ACCESS
If necessary, the batteries(1) are accessible from the rear panel of the oscilloscope after turning the "quarter turn" (2) lock anti-
clockwise; use a coin (3):
Spent batteries must not be treated as ordinary household waste. Take them to the appropriate recycling collection point.
2.4. CHANNEL INSULATION
The two oscilloscope input channels are insulated from each other and from the earth and the mains power supply block.
This insulation is double or reinforced in compliance with the safety standards IEC/EN 61010-1 or BS EN 61010-1 and
IEC/EN 61010-2-030 or BS EN 61010-2-030.
This makes it possible to make measurements on installations or systems connected to the electricity supply network for
voltages of up to 600 V in CAT III. The common mode authorised between the two channels is 600 V in CAT III.
Thus the operator, the test systems and the environment are completely protected at all times.
Any voltage (even dangerous) on one channel will not be present on the other channel. The low points of the inputs are
completely insulated, so there is no possibility of the low points looping (which can be dangerous and highly destructive).
The oscilloscope insulation is as shown in the diagram below:

9
The use of accessories with a voltage and/or category lower than 600 V CAT III reduces the operating range to the
lower voltages and/or categories.
Your oscilloscope is rated 600 V CAT III; at least 600 V CAT III accessories must be used. The accessories shipped
with the instrument allow this .

2.6. ADVICE FOR USE OF THE SENSORS
2.6.1. CONNECTION OF THE REFERENCE CONDUCTORS TO THE SENSOR
Distribution of stray capacitors:
It is imperative, considering the stray capacitances, to correctly connect the reference conductors for each sensor. The conductors
should preferably be connected to the cold points to avoid the transmission of noise by the stray capacitance between modes.
External power supply
connector
Input Channel "B"
Input Channel "A"
Isolated optical connector

11
The noise of the digital ground (earth) is sent to the analogue input by the stray capacitance.
Reminder: In order to prevent electric shocks or possible res:
Never use accessories on which the casing is accessible if it has a voltage of > 30 Vrms compared to the earth.
This precaution is necessary for example for sensors with an accessible metal BNC. The accessories shipped
with the instrument are compliant.
Reminder: Denitions of the symbols and precautions of use per the IEC/EN 61010-2-032 or BS EN 61010-2-032
standard, max. voltage 600 V in Category III (with respect to earth and between the two channels).
2.7. SENSOR CALIBRATION
The calibration output (3 Vpp, 1 kHz) for the sensors is underneath the battery cover (see § 2.5.2. Back face).
To obtain optimum response, the sensor's low frequency compensation must be adjusted. To carry out this adjustment, the two
channels of your oscilloscope must be disconnected from the measured circuits before opening the battery housing cover.
Connect the sensor to be adjusted to the calibration
output under the battery housing cover, as shown
opposite.

12
Select the DC coupling for the channel to which the sensor is connected and run an autoset (icon opposite) to carry out
pre-setting. Adjust the sensitivity and the vertical o󰀨set of the channel so that the signal lls the screen, and adjust the time base
to 200 µs to view a signal period on the screen. Turn the BNC base of the sensor in order to access the sensor adjustment screw:
In the example opposite the sensor is over-compensated:
an overshoot occurs.
Turn the screw in either direction until the signal is horizontal
and looks like the screen shown opposite. Your sensor is now
calibrated, so you can turn the BNC base again to close access
to the adjustment screw.
Replace the battery cover in order to use your instrument in optimum safety conditions.
