Introduction
All TempScan/1100 and MultiScan/1200 components are carefully inspected prior to shipment.
When you receive your temperature-and-voltage measurement system, carefully unpack all items from the
shipping carton and check for any damage which may have occurred during shipment. Promptly report the
damage to the shipping agent and your sales representative. Retain all shipping materials in case you must
return the unit to the factory. Refer to the QuickStart Guide at the front of this manual for installation
instructions.
The TempScan/1100 and MultiScan/1200 are high-speed, compact, rack-mountable instruments that
measure up to 992 or 744 channels of temperature or voltage, respectively. Because of their unique
architecture, both instruments offer unrivaled low cost per channel. They connect to a computer via
IEEE 488 or RS-232 interfaces, or via modem, and can be disconnected from the computer for
stand-alone operation.
TempScan/1100
The TempScan/1100 is well-suited for temperature and lower-voltage measurement because its solid-state
scanning provides temperature readings at speeds up to 960 channels per second, an important feature in
applications that require monitoring of tens or hundreds of channels.
MultiScan/1200
The MultiScan/1200 is ideal for temperature and voltage measurements that require channel-to-channel
isolation. The unit provides 500 V of channel-to-channel isolation for voltage, and 200 V of channel-to-
channel isolation for thermocouples. The MultiScan/1200 uses relays to provide isolation and to scan
thermocouples and volts at up to 147 channels per second. The unit can also digitize waveforms on
a single channel at up to 20 kHz.
