Integra Series Multimeter/Switch Systems Model 2700 Measure the ratio or average of two input channels. View a channel of interest without interrupting a scan by using the Channel Monitor feature. Built-in linearization for thermocouples, RTDs, and thermistors. Front panel input jacks simplify manual probing, troubleshooting, and calibration. Built-in signal conditioning with 1000V isolation simplifies system configuration and ensures good measurements.
Integra Series Multimeter/Switch Systems Model 2701 Built-in signal conditioning and statistical analysis is configurable per channel for maximum flexibility. Its familiar DMM-like front panel scheme makes the Model 2701 easy to use on the bench or in the rack. Select or change functions with the press of a button. Large memory buffer (450,000 readings) for storing data without tying up the network.
Integra Series Multimeter/Switch Systems Model 2750 Use mX+b or 1/x % scaling to convert sensor/transducer outputs directly into engineering units. View slot capacity and channel closure status from front panel. Built-in independently programmable alarm limits per channel. Front panel input jacks simplify manual probing, troubleshooting, and calibration. Open lead detection protects against false readings due to lead disconnections.

Integra Series Multimeter/Switch Systems Channel Configuration Capabilities Channel Configuration Capabilities — Scanning Capabilities • Measurement functions: An Integra system can measure many different parameters: DC voltage, DC current, AC voltage, AC current, 2-wire Ω, 4-wire Ω, voltage clamped Ω (2750 only), temperature (using thermocouples, RTDs, and thermistors), frequency, period, and continuity.
Integra Series Multimeter/Switch Systems • Scan interval: The user can set the interval after which each succeeding scan will begin. Scan intervals can be set anywhere from 0 to 99 hours in increments of 1ms. Scanning Capabilities — Choice of Communication Interfaces • Scan sequence/omitting channels: In addition to scanning in numerical sequence, the system can be programmed to skip any channels that are not required for a particular test.
Integra Series Multimeter/Switch Systems Triggering and I/O Capabilities Trigger sources Any of the following sources can be used for triggering a reading or scan sequence: A. Immediate: An Integra Series system self-triggers automatically. This default method is the simplest way to take a measurement on a single channel. B Triggering and I/O Capabilities B. An external trigger is received via the Trigger Link connector. Triggering through Trigger Link is very precise (<0.
Triggering and I/O Capabilities — On-board Data Storage Integra Series Multimeter/Switch Systems Alarm Limits/Digital Outputs The digital output lines can trigger external alarms without the need for a PC connection. The instrument can be programmed to provide alarms when any pre-set limits are breached. Limits can be applied to all measurement functions except continuity, which has its own alarm beeper. The limit test is performed after “mX + b” and math operations.
All current set-up information for individual channels and the mainframe is battery backed and the measurement data is stored in the non-volatile memory. Therefore, while the instrument is switched off, the configuration for each channel is saved in the memory, then automatically recalled when the product is switched on again.
Digital Filtering — NPLC — Line Cycle Synchronization — Autozero — Low Ohms Measurement Multimeter/Switch Systems Integra Series Digital Filtering For each major measurement function, users can employ either averaging or advanced digital filtering to reduce noise and increase the effective resolution. Averaging Filter The averaging filter operates over a range of from two to 100 readings. All readings included in the filter range are weighted equally.
Multimeter/Switch Systems Offset Compensation — Voltage Limit/Dry Circuit Ohms — Temperature Measurements Integra Series Offset Compensation For more accurate low resistance measurements, all Integra systems provide the offset compensation mode to eliminate errors from the thermoelectric EMF effects (VEMF). During the measurement cycle, the built-in ohms current source is turned off, then turned on again, and the resulting EMF error is automatically subtracted.
Integra Series Multimeter/Switch Systems Cold Junction Compensation Methods Thermocouple measurements always require that the temperature be known at the point where the thermocouple is connected to the instrument. This connection point is known as the “cold junction.” The Integra systems support three different methods for including this “cold-junction” temperature in the temperature measurements.
Integra Series Multimeter/Switch Systems Start-Up Software This free TestPoint runtime offers basic datalogging capabilities that can get a system “up & running” almost immediately. With just a few clicks of the mouse, this software can confirm the system’s hardware, wiring, communications, and software drivers are installed and operating correctly. It can also configure instrument functions and perform simple data acquisition tasks.
Integra Series Multimeter/Switch Systems Datalogging/Data Acquisition Software Custom Application Development with VISA Based IVI Driver Software ExceLINX-1A SWITCH/MEASURE SYSTEMS For advanced datalogging tasks, this powerful and economical add-in utility for Microsoft® Excel makes it simple to acquire data from the Integra Series instrument directly into Excel, then employ Excel’s graphic, charting, and analysis capabilities to turn that data into useful information.
