IEEE 488, RS‑232/422, or Hayes-compatible
modem and can be disconnected from thePC 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 to960 channels/s, an important feature inapplications that require monitoring oftens or hundreds of channels.

MultiScan/1200
The MultiScan/1200 is ideal for temperature and voltage measurements that require
more channel-to-channel isolation than
the TempScan/1100 can offer. The unit
provides up to 500V of channel-to-channel
isolation for voltage and 200V of channelto-channel isolation for thermocouples.
The MultiScan/1200 uses relays to provide
isolation and to scan thermocouples andvolts at up to 147 channels/s. The unit canalso digitize waveforms on a single channel
at up to 20 kHz.

Up to 15 Exp/10A expansion chassis can be attached
to a TempScan/1100 or MultiScan/1200

The TempScan/1100 or MultiScan/1200 can support
up to three Exp/11A expansion chassis

The TempScan/1100 and MultiScan/1200 can each accept one
scanning module, which provides all of the required signal conditioning. If your application demands more channels than areavailable on a single module, you can use either the 2-slot Exp/10Aor the 10-slot Exp/11A expansion chassis. Multiple Exp/10A andExp/11A chassis can be daisy chained to a TempScan/1100 orMultiScan/1200, providing up to 30 additional slots. Regardlessof the number of expansion chassis connected, there is only
one link to the computer, via its IEEE 488 or serial interface. As
a result, the TempScan/1100 or MultiScan/1200 appears to the
PC as one unified multichannel instrument.

When attached to the TempScan/1100, each Exp/10A is configurable for 32 or 64 input channels, providing a total expansion capacity of up to 992 channels. When attached to theMultiScan/1200, each Exp/10A is configurable for 24 or 48
input channels, providing a total expansion capacity of up to744 channels.
For TempScan/1100 systems consisting of more than 96
channels, the 10-slot Exp/11A expansion chassis provides an
economical and convenient solution. One Exp/11A provides
up to 320 input channels in a compact and convenient enclosure. Multiple Exp/11A chassis can be connected to one
TempScan/1100 to provide a total system capacity of up to992 channels.

TempScan/1100 &MultiScan/1200 Expansion

For MultiScan/1200 systems of more than 72 channels, the10-slot Exp/11A is recommended and accommodates up to 240
input channels. Multiple Exp/11A chassis can be connected to
one MultiScan/1200 providing a total system capacity of up to744 channels.

The TempScan/1100 and MultiScan/1200 instruments can eachcontrol up to 15 Exp/10A two-slot expansion chassis. The Exp/10A’s
form factor is identical to that of either instrument.

Measurement Modes
TempScan/1100

MultiScan/1200

Scan Technique. The TempScan/1100 uses a technique whereby
groups of 16 consecutive channels are scanned during every AC
line cycle (i.e., channels 1 to 16 are scanned during the first ACline cycle, channels 17 to 32 are scanned during the subsequent
AC line cycle, and so forth). This results in maximum measurement rates of 960 channels per second (60 Hz) or 800 channels
per second (50 Hz).

The MultiScan/1200 offers three measuring modes for application flexibility. These include a line-cycle integration mode, ahigh-speed multichannel scanning mode, and a single-channel
burst mode. A discussion of the particular attributes of eachmeasuring mode follows.

High-Speed, Multichannel Scanning Mode. When theMultiScan/1200’s line-cycle averaging is disabled, the unit
can average 1, 2, 4, 8, 16, or 32 samples per channel. When theunit is configured to take one sample per channel, it can scan
147 channels/s—or all of its potential 744 expansion channels
in approximately 5 seconds. This is important if the application
involves monitoring tens to hundreds of channels. By contrast,
data loggers and other temperature measuring instruments­typically acquire readings at only 5 to 20 channels/s.

Single-Channel Burst Mode. In single-channel burst mode, theMultiScan/1200 can sample at up to 20 kHz on a single channeland store the data in its memory, which can be expanded up to
8 Mbytes. When performing post-acquisition waveform analysis
such as Fast Fourier Transforms (FFTs), the unit can return eachdata point in a waveform to your program. Alternatively, theunit can provide a true RMS value of the equivalent AC voltage.

Line-Cycle Integration Mode. The MultiScan/1200’s ability tosample and average 32 measurements per line cycle makes it
useful for high-accuracy applications and is recommended forthermocouple measurements. What’s more, when engaged inline-cycle averaging, the unit provides AC or DC voltage, or
linearized and compensated thermocouple-based temperature
readings at up to 44 channels/s. The MultiScan/1200’s AC voltage measurement capability is ideal for power-line monitoring
applications. For each measurement, the unit calculates theequivalent true RMS voltage based on 32 samples it acquires
during each AC line cycle.

Scan Interval. For applications that require the logging of data at
a specified time interval, the TempScan/1100 offers a programmable scan interval. The effect of the scan interval is illustrated

TempScan/1100 & MultiScan/1200
General Information
Scanning Capabilities

AlarmsThe TempScan/1100 and the MultiScan/1200 provide an arrayof scanning capabilities to meet your application requirements.
Because data-logging applications frequently require the logging of readings at fixed time intervals, the TempScan/1100 and
the MultiScan/1200 use the standard hours-minutes-seconds(hh:mm:ss.s) format to specify the time interval between
channel scans. Users can configure the units to begin and end
data logging on a specified event — such as a TTL signal, temperature level, IEEE GET, alarm condition, or absolute time of
day — or upon ­completion of a specified number of readings.

Many process-control applications require periodic monitoring
until the occurrence of an alarm condition; then they require
the acceleration of measurement and the provision of closedloop control signals until the process returns to a steady state.
The TempScan/1100 and the MultiScan/1200 offer a numberof capabilities and features that facilitate such applications. For
example, they provide 32 digital alarm outputs that can be activated on a per-channel basis via user-specified alarm conditions,and they automatically return their alarm outputs to steady stateonce limit conditions are resolved.

Two Programmable Scan Rates. The TempScan/1100 and the­MultiScan/1200 offer two programmable scan rates for applications that require acceleration of the measurement rate on a
specified event, such as an alarm condition. For example, you canprogram the instruments to sample once per minute and then,upon the occurrence of a specified alarm condition, switch tosampling once per second. Upon cessation of the alarm condition, the units resume sampling at the rate of once per minute.

The units’ ability to automatically update alarm outputs in realtime affords you greater control of your applications and reduces
your programming burden by eliminating the need for constant,per-channel monitoring by the controlling computer.
In addition, the units can update alarmed output channels inreal time, at their programmed scan rates, and can alert the hostcomputer of active alarm conditions via an IEEE 488 service
request (SRQ).

Accuracy
The TempScan/1100 and the MultiScan/1200 have a number offeatures and capabilities that enable them to deliver the highaccuracy demanded by many research applications.

Real-Time Clock
The TempScan/1100 and the MultiScan/1200 each feature areal-time clock that allows you to synchronize acquisition toa specific time of day. During acquisition, the TempScan/1100
and the MultiScan/1200 store the time and date of every data
scan in memory, enabling later retrieval of this information foruse in plotting and analyzing measurements over time. The
instruments also time and date stamp each channel’s high andlow excursions, providing a precise time record of a channel’s
minimum and maximum values.

High Resolution. Each unit is equipped with a high-speed
16-bit A/D converter. This enables the TempScan/1100 to offer up
to 0.1 ˚C and 3.05 µV resolution with the TempTC/32B scanning
module and allows the MultiScan/1200 to offer the same with
the MTC/24 scanning module.
Noise Filtering. The TempScan/1100 filters AC line cycle noiseby sampling and averaging 16 measurements per line cycle. The
MultiScan/1200 does so by sampling and averaging 32 measurements per line cycle. The MultiScan/1200 also offers the additional
flexibility to average across multiples of 1, 2, 4, or 8 line cycles.

MemoryFor high-speed and long-term data logging, the TempScan/1100
and the MultiScan/1200 are equipped with 128 Kreadings of data
storage. Because individual measurements are not necessary for
all data logging applications, the units make each channel’s high,low, and last readings available throughout acquisition.

High-Accuracy Cold Junction Compensation. The TempTC/32B
and the MultiScan/1200’s MTC/24 thermocouple/volt scanning
modules both feature multiple, strategically located temperature
sensors that provide high-accuracy, cold-junction compensation
across all of its inputs.
Accurate Linearization. The TempScan/1100 and the­MultiScan/1200 enable quick and accurate linearization by providing built-in lookup tables for popular thermocouple types,
including J, K, T, E, R, S, B, and N.
