CTR5000 Operating Instructions
ASL operating instructions, model CTR5000 15
The CTR5000 is ASL’s first AC bridge with Smart probe capability. It is also the fastest
commercially available bridge for its specifications.
Overall system accuracy is better than  4m  , (at 20  C  5  C - see specification section),
equivalent to a temperature measurement accuracy of  10mK.
Two measurement channels (A and B) are provided on the front of the instrument. The
CTR5000 may be expanded up to six channels with the addition of two more channels (C and
D), or four more channels (C, D, E and F) on the rear of the instrument; differential mode
operation is provided for these channels. A separate channel connection is supplied for the
expansion switchboxes.
Up to 64 channels may be added with the addition of external CTS5000 switchboxes. Two
switchbox models are available – the CTS5000–08 and the CTS5000–16 (with 8 or 16 channels
respectively). The switchboxes use an expansion connector on the rear of the instrument.
Channels A, B (C, D, E and F) operate independently of the switchboxes.
Unlike previous instruments, units may be set on a channel basis, so, for example, channel A
may be set to
 C and channel B to display ohms.
