A Greater Measure of Confidence

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 .
