4. SOFTWARE CONFIGURATION
AND CALIBRATION
• CALCULATED Calibration Values (on the
ABSOLUTE Calibration page only). This set of
numbers is determined by the current entries of the
page’s
“CAL” fields (described below). Some of
the numbers may be missing, if one or more “CAL”
fields are blank. When you press the button
labeled
Save and Send Calculated Calibration
Values
, these numbers will be sent to the connect-
ed 3000PLUS instrument, and will be permanently
transferred to the present configuration.
•
CONFIGURATION Calibration Values (on the
ABSOLUTE Calibration page only). These repre-
sent the calibration data
currently stored in this con-
figuration
. They do not depend directly on the
present “CAL”-field entries, as do the “calculated”
values, and are changed only when absolute or
two-point calibration is actually performed.
In very general terms, the scaled analog output of a
3000PLUS with a 5D64 conditioner is calibrated by
means of three variables:
1. the 5D64 module’s nominal full-scale input
RANGE
(RNG)
, expressed in volts DC
2. a MODULE SCALING FACTOR (MSF) to be used
as a gain multiplier for the module’s nominal full-
scale input range
3. a
MODULE INPUT OFFSET (MIO)—i.e., a percent-
age of full-scale input range applied to the mod-
ule’s
pre-amplified (input) signal, in order to remove
signal bias inherent to the source transducer
PLEASE NOTE: For a 3000PLUS with 5D64 conditioner,
the
ABSOLUTE calibration technique described below
is sufficient for most purposes, guaranteeing an accura-
cy for calibrated measurement data that exceeds the
module’s rated accuracy. Thus, no further “dead-
weight” calibration need normally be performed. You
may, however, wish to apply
TWO-POINT (DEAD-
WEIGHT)
calibration simply to improve on the Configu-
rator’s “absolute” calculations, when there are at least
CALIBRATION OVERVIEW
The two methods described below are provided by the
3KP Configurator software for calibration of a
3000PLUS instrument with installed Model 5D64.
To calibrate your 3000PLUS by either or both methods,
you must first go to the
Calibrate / Configure page
and click the button labeled
Calibrate This Instru-
ment
. This will open the Instrument Calibration win-
dow to display the
ABSOLUTE Calibration page (Fig.
13). To switch between the two calibration methods,
click on the tab for the desired method.
NOTE: If the Configurator is unable for any reason to
communicate with the 3000PLUS, the
Instrument Cali-
bration
window cannot be opened (see the ON-LINE
HELP section titled
“Setup and Testing of Serial
Communications”
).
When it is opened, the
Instrument Calibration window
will display (in the center of its upper section) a “live,”
continuously refreshed readout of the connected
meter’s basic
scaled output channel (Channel 1).*
The
Instrument Calibration window will also display
the following sets of “CALIBRATION VALUES”:
•
ACTUAL (“Live”) Calibration values (in the upper
right corner). These represent the calibration that is
currently in effect for the connected 3000PLUS
instrument.
Also displayed here is the current
shunt state of the installed 5D64 module, and the
date/time of the
last 3000PLUS calibration per-
formed via the 3KP Configurator.
4.E SOFTWARE CALIBRATION
OF THE 3000PLUS WITH 5D64
PLEASE NOTE: The following is only a general overview of Configurator-based calibration of the
3000PLUS with installed Model 5D64 DC Voltage Conditioner Module. Complete and detailed
instructions for the entry of calibration values and for loading these values into the meter itself
(when required) are given in the Configurator ON-LINE HELP sections titled “Absolute Calibra-
tion with an Installed Model 5D64 DC Voltage Conditioner” and “Two-Point (‘Deadweight’)
Calibration with an Installed Model 5D64 DC Voltage Conditioner.”
* If the decimal-point precision of the configuration’s currently
entered
Full-Scale Reading in Engineering Units (FSU) is dif-
ferent from that of the current “live” scaled output reading of
the connected 3000PLUS, you will be alerted to this fact. Dur-
ing the course of either ABSOLUTE or TWO-POINT CALIBRA-
TION, the instrument’s display resolution will be automatically
changed to accord with the
configuration’s “FSU” precision.
