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 power cord 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 Models OX5022-CK and OX5042-CK combine three instruments into one:
•
20MHz or 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 Insulation
The two oscilloscope input channels are insulated from each other and from the ground/earth and the
main 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 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.
