Model 6664C
8 AND 16-CHANNEL LOW THERMAL QUAD SCANNERS
Complements All Guildline Bridges and Fully Automates Measurements
Guildline's 6664C Low Thermal Quad Scanner is the first
commercial scanner capable of operating at 1000V. This has
greatly improved the measurement/calibration throughput of
standards laboratories, since many high ohm measurements
can now be automated. High ohm measurements are typically
hard to make and very time consuming because of the low
signal/noise ratio. With a Guildline model 6664C scanner and
software, these hard-to-make high ohm measurements (up to
100 G) can be automated and scheduled at any time that is
convenient to the metrologists, even at night and over the
weekends.
This scanner is designed to work with a Guildline 6622A
Automatic Direct Current Comparator (DCC) Resistance Bridge,
a model 6622T Temperature Bridge or a Teraohmmeter (model
6520). Still have one of our older Guildline Automatic Bridges
such as a model 6675A? Our software and scanner also support
all previous Guildline' models.
Both 8-channel and 16-channel models are available. Like other
6664C FEATURES Guildline products, the 8-channel scanner can be expanded to
a 16-channel model, giving our customers exactly what's
Withstand up to 1000 V DC to provide fully needed now and the flexibility for future growth.

Gold flashed Tellurium Copper Terminals Measurements At Up to 1000 V
Special low thermal latching relays are used. Leakage between
the high and low circuits is reduced by switching them on
different printed circuit boards.
Protection circuits prevent selection of more than one 4
terminal connection on a channel output at the same time.
Front panel indicators show which channel is selected on each
output.
