Product Overview and Specifications
Introduction 1
1-3
Introduction
This chapter supplies information about the Product, the manual set, safety information,
contact information, and specifications.
Product Overview
The Fluke Calibration 1586A SUPER-DAQ Precision Temperature Scanner (the Product
or Instrument) is a 45 analog channel bench-top measurement instrument that measures
and records temperature, resistance, dc volts, and dc current (see Table 1-1). See the
Specifications section for information on the types and ranges of the measurement inputs
the Product can accept.
Features of the Product include:
•Temperature Accuracy – Measures temperature with uncertainty as low as 0.01 °C
with a PRT, 0.003 °C with a thermistor, or 0.2 °C with a thermocouple. PRT
accuracy is enhanced by 4-wire sensing that cancels out lead-wire resistance,
bidirectional source current that cancels thermoelectric EMF in the PRT, and ITS-90
characterization that accurately relates resistance to temperature.
•Scan – Sequentially scan up to 45 analog channels per scan sweep. In addition, the
Product also has 20 math channels, one DIO channel, and one TOT channel that can
be included in scan. A scan can be manually controlled from the front panel or
triggered with a variety of triggers such a timer, an alarm, an external source, or a
remote SCPI command.
While a scan is in progress, all channel values can be viewed on the display in a
spreadsheet format along with statistics such as average, standard deviation,
minimum, maximum, peak-to-peak, and rate-of-change. With the Graph feature,
channel measurement data for up to four channels can be plotted and viewed on the
display. Users can toggle the data mode with a softkey to view live data or historical
data.
•Monitor – View the measurement value or the statistics of a single channel. Monitor
is an independent feature that can be used while a scan is in progress or inactive.
Much like the Scan feature, the statistics of the single measurement can be viewed on
the display or be shown in a graph.
•Digital Multimeter Functionality (DMM) – Function that presents the user with
familiar DMM features and controls like a standard bench DMM. The DMM can
show 6 ½ digits on the display. To visualize trend data, the DMM provides additional
functionality to graph and see measurement statistics.

•Data Storage - Store up to 20 MB of data and channel setup files directly to the
internal non-volatile memory or an external USB drive. Data can also be transferred
to a PC with a USB drive or LAN TCP/IP interface at the rear of the unit with SCPI
interface command sets.
•Alarms – Each channel can be assigned two independent alarms to indicate when
either an upper (HI) or lower (LO) range has been exceeded. The alarms can be
configured to output a digital signal from the rear-panel alarm output for control of
external devices.
•Digital I/O (DIO) – The Product is equipped with a digital 8-bit transistor-transistor
logic (TTL) port that can sense and output. When the DIO channel is included in the
scan list, the value of this port is recorded in the scan data record on each scan with a
value range of 0 to 255 based on the port state when it is read.
•Totalizer – The Product is equipped with a unidirectional, resettable totalizer with an
input count capability of 1,048,575 (20 bits). Counter increment is accomplished
through a change to a digital signal or contact closure to the totalizer input terminals
on the rear of the Instrument.
•Remote Operation – Remotely operate the Product with remote SCPI commands
from application software over a rear-panel USB or LAN TCP/IP connection.
•Automated Sensor Test –Automatically sets the temperature of a Fluke
Calibration dry-well calibrator or temperature bath connected to the rear-panel
RS-232 port. Monitors temperature stability, and measures the readings of
temperature sensors and a reference thermometer when the temperature is stable.
•DAQ-STAQ Accessory –Multiplexer module provides quick and convenient
connection of temperature sensors with Fluke's patented spring-loaded DWF
terminals.
