Channel Isolation - AEMC OX 5042 Quick Start Manual

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.
