Revised 07/07/08

For temporary but critical on-site data acquisition, the portable, high-speed MeasuringPAD™ offers a convenient, economical alternative

to an elaborate test and measurement installation. This sturdy hand-held instrument can be used in a wide range of manufacturing,

laboratory, plant operations, and quality control applications. Rapidly collecting, monitoring, and displaying multiple sensor inputs, it

can be used for troubleshooting, maintenance, process tuning, fault recording, trend analysis, and much more. Configured and operated

through an easy-to-use color touchscreen interface, MeasuringPAD continuously scans all active inputs, digitizing with 16-bit A/ D while

checking for limit-violation triggers and refreshing its memory buffer of 10 kHz per input.

Real-Time Data Monitoring

MeasuringPAD provides live readout of up to sixteen differential analog inputs and
up to eight logic-level digital inputs. As numerical measurements are monitored
for exact conformance to user-entered setpoints, the vivid color-coded status display

lets you size up your test or process
at a glance. To ensure true
“finished-answer” readability, analog
signals are easily scalable to desired
engineering units.

Convenient input “pods” allow fast
and easy hookup of machine- or
process-dedicated sensors – including
DC/AC Low and High Voltage sources
(from 100 mV to 300 V), DC/AC
Low Current sources (4 to 20 mA),
and most Thermocouple types.
Digital inputs are standard TTL-level
signals from switches, contacts,
encoders, pickups, and other
frequency-generating devices. They
may be used to trigger the logging
of data, to perform programmable
counting and timing operations,
and to monitor frequency and

quadrature. Up to eight internal
cross-channel math calculations can also be set up to display and monitor additional
process variables such as horsepower, efficiency, and corrected flow – plus signal
max /min and average values.

High-Speed Data Recording

You can instruct MeasuringPAD to sample scaled measurements at a regular time
interval – or, immediately on detection of any specified trigger event, to begin
recording at a special rate that can be up to a microsecond-level “burst” speed.
Instantly stored on a standard CF memory card in a simple and universally compatible
ASCII text format, data records are both time- and trigger-stamped, and may be
directly imported by all kinds of third-party programs for post-analysis and report
generation, without the need for special drivers or version-dependent operating

systems. If desired, records of data

values as they existed just prior to a

triggering event can be included in

the stored data file. The touch of a

button will display a scrollable

spreadsheet report of all currently

logged data, including time and

event indication.

PAD

Using MeasurePAD’s unique

touchscreen pages, setting up the

instrument literally takes seconds. Simple user selections and clear,

intuitive pathing make the setup process both easy to use and easy to

learn. Once created, multiple test-specific setups can be stored for

instant reloading.

Multichannel Data Display

For instant operator interpretation of measurement results, the backlit color LCD furnishes real-time display of measured and calculated values in a number of programmable formats, including

• bargraph, for rapid visual comparison of up to sixteen
active parameters

• trend, for simultaneous, independent timeplotting of up to four
active parameters. Ideal for comparing energy and process /
production parameters for energy reduction studies.

• scope, for live display of up to four active waveform inputs in
a conventional oscilloscope mode

• discrete Fourier transform (DFT), for harmonic analysis

of a selected analog input.
