Precautions Before Use
The operator and/or the responsible authority must carefully read and completely
understand the precautions before use. If you use this instrument in an unspecified
manner, the protection it ensures can be compromised, thus putting you in danger.
• This instrument is designed for use:
-indoors
-in a level 2 pollution environment
-at an altitude below 2000 m
-at a temperature between 0° C and 40° C
-with a relative humidity of less than 80% up to 35° C.
• The safety of all systems, including the instrument, is the responsibility of the
operator.
• It can be used for measurements on 600V CAT III circuits, relative to the ground/
earth.
• Before each use, check the condition of the insulation on the cables, boxes,
sensors and accessories. Any element on which the insulation is damaged
(even partially) must be taken out of service for repair or disposal.
• Respect the environmental and storage conditions.
• The external power supply must be connected to the instrument and to the
network (98 to 264 VAC).
• The power supply to the instrument is fitted with an automatically resettable
electrical protection after disappearance of the fault.
• As a safety measure, only use factory supplied parts and accessories.
• It is advised to use individual safety protection whenever the environmental
situations in which the instrument is used require it.
• When handling the sensors or test probes, do not place your fingers beyond the
physical guard.
• If the battery housing cover is absent, damaged or incorrectly positioned, the
instrument must not be used other than to adjust the sensors.
Definition of Measurement Categories (CAT)
CAT IV Measurement category IV corresponds to measurements taken at the source
of low-voltage installations.
Example: power feeders, counters and protection devices.
CAT III Measurement category III corresponds to measurements on building installa-
tions.
Example: distribution panel, circuit-breakers, machines or fixed industrial
devices.
CAT II Measurement category II corresponds to measurements taken on circuits
directly connected to low-voltage installations.
Example: power supply to domestic electrical appliances and portable tools.

Symbols Used
CAUTION! Risk of electric shock. The voltage at the
parts marked with this symbol may be dangerous.
Warning: Risk of danger. Refer to the operating manual to find out the nature of
the potential hazards and the action necessary to avoid such hazards.
Earth/Ground
Dual insulation
The trash can with a line through it means that in the European Union, the prod-
uct must undergo selective disposal for the recycling of electric and electronic
material, in compliance with Directive WEEE 2002/96/EC.
The CE marking guarantees conformity with European directives and with regu-
lations covering EMC.
Application or withdrawal not authorized for non-insulated conductors carrying
dangerous voltage levels
Power Supply
The oscilloscope is supplied with one external power supply and set of 6 x 1.2V NiMH
rechargeable batteries 2700mA/h.
When the supplied wall plug is connected from the instrument to an external power
source, battery power is not needed. The batteries are only used when there is no
external power supply available.
Before the first use, start by fully charging the battery.
NOTE: The batteries automatically begin recharging when the Oscilloscope is powered off, but
connected to an external power supply.
When the batteries are recharging, the Battery Charge LED on the front panel will turn
on steady.
The LED will blink in the following situations:
• pre-charge of very low batteries
• temperature is too low or too high
• batteries are damaged
When the charge is complete, the LED will turn off.
If the batteries need to be replaced, they must be replaced with NiMH rechargeable
batteries. Battery charge life is guaranteed for same-capacity batteries (in mAh) as
those shipped with the oscilloscope.
To remove the battery cover, use a coin to turn the slot on the back of the unit counter-
clockwise.

Description
The Handscope Oscilloscope Model OX5042-CK combines three instruments into one:
• 40MHz oscilloscope
• Independent 8000-count multimeter with power measurements
• Built-in harmonic analyzer out to the 31st harmonic (fundamental between 40
and 450Hz)
The instrument operates at a constant acquisition depth of 2500 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 buttons 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
Channel Isolation
The two oscilloscope input channels are isolated from each other and from the ground/
earth and the main power supply block. This isolation is provided by double or rein-
forced insulation, 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 600V in CAT III. The common mode
authorized between the two channels is 600V 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).
NOTE: The use of accessories with a voltage and/or category lower than 600V CAT III reduces
the operating range to the lower voltages and/or categories.
The oscilloscope is rated 600V CAT III; at least 600V CAT III accessories must be used.

Use of the 10:1 Probes
Distribution of stray capacitors:
Considering the stray capacitances, it is imperative to correctly connect the reference
conductors for each probe The conductors should preferably be connected to the cold
points to avoid the transmission of noise by the stray capacitance between modes.
The noise of the digital ground (earth) is sent to the analog input by the stray capaci-
tance.
NOTE: In order to prevent electric shocks or possible fires, never use accessories on which the
casing is accessible if it has a voltage of > 30Vrms compared to the ground.
10:1 Probe Calibration
To obtain optimum response, the probe’s low frequency compensation must be
adjusted.
NOTE: To carry out this adjustment, the two channels of your oscilloscope must be
disconnected from the measured circuits before opening the battery housing cover.

The calibration output (3Vpp, 1kHz) for the probe is underneath the battery cover.
To remove the battery cover, use a coin to turn the slot on the back of the unit counter-
clockwise.
Connect the probe to be adjusted
to the calibration output under the
battery housing cover, as shown.
• Select the DC coupling for the channel to which the probe is connected and run
an Autoset 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 200µs to view a signal period on the
screen.
• Turn the BNC base of the probe in order to access the probe adjustment screw:
In this example, the probe is over-compesated:
an overshoot occurs.
Turn the screw in either direction until the
signal is horizontal and looks like the screen
shown opposite. Your probe is now calibrated.
Turn the BNC base again to close access to
the adjustment screw and replace the battery
cover.
Remote Programming
The oscilloscope can be programmed remotely from a computer by using the SX-
METRO software, which is located on the CD-ROM supplied with your instrument. This
software is used to:
• Configure the instrument
• Perform measurements and retrieve the results
• Transfer files (traces, configuration, screenshots, etc.)
To communicate between the instrument and the computer:
• Connect the USB end of the cable to one of the PC’s USB ports (if necessary
install the driver shipped with the cable).
• Connect the optical connector to the oscilloscope, after first powering it up.
• Open SX-METRO; select USB communications and wait for communication to
be established (in the event of a problem, refer to the SX-METRO instructions).
