ENGLISH
1 Identification
Ideally suited for educational uses, the oscilloscopes model JO 20 MHz
combine high-performance technical characteristics and an education-
oriented design:
•
Functions easily identified by their colour coding.
•
Easier control setting thanks to the marking of the usual position.
•
Indications in French language.
•
Six-inch display with on-screen grid (parallax-free).
•
Screen illumination.
•
Two channels, dual trace (simultaneous x1 and x5 or x10 curves).
•
Sensitivity: 5 mV/division, 1 mV/division (with x5 expansion).
•
Video synchronisation.
•
Bandwidth: 20 MHz.
•
Z input.
These numerous features allow these oscilloscopes to be used even by
young students who can then view and study all periodical signals with an
arbitrary shape and a frequency spectrum below 20 MHz, 40 MHz, or 60
MHz.

Installation

•
When unpacking, check the instrument for proper condition and
absence of damage during transport.
•
Also ensure that the factory-preset supply voltage (240 V) matches
the characteristics of your mains network:
If it does not, use a screwdriver to remove the fuse holder showing the
voltage values and substitute a fuse having the value shown at the rear of
the instrument. Reinstall the fuse holder so that the mains voltage value on
the fuse holder faces the triangular symbol.
