Multimeter/Data Acquisition/
Switch Systems
Important Features and Benefits
• Full per-channel configurability—Each channel can be
independently configured for making measurements. The
parameters that can be chosen for each channel include speed,
range, resolution, number of power line cycles (NPLC), filtering
type, offset compensation, math functions to be displayed,
CJC type, RTD type, frequency gate time, “m” and “b” values in
mX + b format, HI/LO limits, low W (Model 2750 only), ratio
calculation, and thermistor type.
• Channel monitor feature—Monitor any specific input channel on
the front panel display during a scan. This feature can also serve
as an analog trigger to initiate a scan sequence based on some
external factor, such as a temperature rising above a pre-set
limit. Only the data of interest is acquired, so there’s no need to
spend hours searching through reams of normal readings to find
anomalous data.
• Front/rear switch—Switching between the front and rear panel
measurement inputs is as easy as pressing a button. Users can
select the front panel inputs for tasks such as system setup and
verification, manual probing, troubleshooting, and calibration,
while the rear panel inputs through the modules allow fast,
automated multiplexing and control.
• Battery-backed setup memory—Up to four different setup
configurations can be stored in onboard memory. If the line
power fails during a scan, the system will resume scanning
where it stopped once power is restored.
• Relay counting—Provides preventive maintenance of the system
and switches.
• Memory buffer—The mainframe’s non-volatile wrap-around
reading memory allows continuous, unattended datalogging
over long periods. Data in the buffer can be transferred to a PC
controller automatically as new data is acquired. The real-time
clock can be used to time- and date-stamp readings for later
review and interpretation.
• 2 TTL-level digital inputs—Use to implement external triggers to
initiate a scan sequence.
• 5 “per-channel” HI/LO alarm limit TTL outputs—Trigger
external alarms or perform other control functions without a PC
controller.
• Dry circuit ohms (20mV clamp)—Protects sensitive devices from
damage and prevents self-heating errors during testing (Model
2750 only).
• Virtual channel—Stores the results of channel-to channel ratio
and average math operations.
• Onboard statistical analysis—Mathematical functions available
at the push of a button are channel average, mX+b scaling,
minimum, maximum, average, and standard deviation.
• GPIB and RS-232 interfaces (Models 2700 and 2750)
• Ethernet and RS-232 interface (Model 2701 only)
Which Integra Mainframe is the Best Choice for the Application?
Use this selector guide to decide which Integra Series mainframe offers the combination of features
and capacity that’s right for a specific application. If testing requirements change in the future,
switch/control modules and test code can be easily re-used.
