Description of the instrument
Description of the instrument
Presentation The particularity of these oscilloscopes is that they group 3instruments in
one:
Harmonic
analyser
Digital
oscilloscope
Multimeter
OX 5022
OX 504
2
•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 first 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.
Power supply
The oscilloscope is delivered with:
•one external power supply ÆVoltage: 12 VDC
Power: 1.25 A
Polarity:
•6 rechargeable ÆNi-MH (1.2 V, 2700 mAh) accumulator 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 flat, defective or even absent.
HandScope II - 7

Description of the instrument
Description of the instrument (cont’d)
Batteries
A "battery empty" indicator appears on the screen when the accumulator-
battery charge level is insufficient 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 off" precedes the automatic shutdown of the instrument.
Charge The batteries are charged when the oscilloscope is powered off but
connected to the external power supply.
During the fast charge of the batteries, the front-panel LED is on.
It flashes in the following situations:
•pre-charge of very flat batteries
•temperature too low or too high
•batteries damaged.
When the charge is complete the LED switches off. The batteries must be
replaced with Ni-MH rechargeable batteries. Battery charge life is
guaranteed for same-capacity batteries (in mAh) as those shipped with the
oscilloscope.
*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 off 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.
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):

Description of the instrument
Description of the instrument (cont’d)
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 61010-1 and IEC 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:
*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.

Advice for use of
the sensors
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.
Connection of the
reference
conductors to the
sensor
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 fires:
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 See p. 4 Input connection and disconnection instructions.

Description of the instrument
Description of the instrument (cont’d)
Sensor calibration The calibration output (3 Vpp, 1 kHz) for the sensors is underneath the
battery cover (see p. 10).
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.
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 offset of the channel so that the signal fills 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:
Connect the sensor to be
adjusted to the calibration
output under the battery housing
cover, as shown opposite.
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.
