Cossor CDU130 oscilloscope

[Alf Fisher]

Hi there, Last week I acquired one of these scopes and wondered if anyone has a manual for it. It is a mains or battery portable and came with rechargeable Ni-Cd D cells which are very likely to be dead. There has been some bodging around the power input connector and I don't want to apply power to the unit and risk blowing it up.
Cheers, Alf

The Cossor CDU130 solid-state portable oscilloscope
has a bandwidth of. d.c. to 15 MHz.
Field effect transistors are used to reduce Y amplifier drift,
eliminate microphony and ensure accuracy at slow timebase sweep speeds.

The sensitivity is 5 mV /division at full bandwidth.
The operation of this instrument is possible with external a.c. or d.c. supplies;
it will also operate for five hours from the internal battery provided as a standard.
A battery charger is contained within the 'scope' and
the battery is protected against reverse charging.
Weight complete is 16.1 lb.

Hi Peter, thanks for the info on the scope. Looks like a good little piece of kit for general testing. There is a empty hole where the mains connector should be and I would like to restore it to its original condition.
Cheers, Alf
