GOSSEN METRAWATT 4
1 Product Description
1.1 Variants and Their Use
METRAwin
®
90 calibration software is a multilingual Windows program for controlling various calibrators for
electrical quantities with the help of a PC, and for documenting calibration results.
The program is available in the following variants:
METRAwin

90-2
Calibration Software for the Following GOSSEN METRAWATT Process Calibrators:
METRACAL MC, METRAHIT CAL, METRAHIT 28C, METRAHIT 28C light and METRA
Hit 18C
These calibra
tors are used primarily for testing and calibrating electrical measuring
instruments and equipment in the field of process measuring and control technology.
They include the following functions: direct voltage simulator, current source and
sink, as well as
simulation of resistors and temperature sensors (thermocouples and
PTCs). The METRACAL MC and METRAHIT 28C versions also include a TRMS
multimeter (V, mA,
Ω, F, Hz, °C/°F). Thanks to inclusion of these multimeter
functions, or by incorporating a separate
METRAHit (in some cases written
METRAHIT) 18S, 28S, 29S, 30M, X
-TRA, EXTRA or ENERGY precision multimeter
with infrared interface into the calibration system, automated calibration of buffer
amplifiers,
temperature measuring transducers and the like can be performed.
The software executes interactive
(DIRECT operating mode) or sequence-
controlled
(TEST operating mode)
setup of the calibrator from the PC via an RS 232 port (with
the help of the BD232 or SI232
-II interface adapter) or a USB port (with the help of
the USB
-HIT or USB-XTRA interface adapter), automatic analysis of measured
values entered manually or read in from the multimeter via the port, and
documentation and archiving of calibration results in a calibration report.
Calibration procedures for
each respective calibration object can be generated and
tested with the program in an uncomplicated fashion. In the case of the METRAHIT
18C and 28C, procedures can also be transferred to the calibrator
’
s memory module,
from which they can be executed auto
nomously (without PC). Measured values (V,
mA) acquired by the METRAHIT 28C can be saved to memory automatically and
subsequently read out and displayed at a PC, and inserted into a calibration report.

Calibration Software for FLUKE D9100, 5100B, 5500A, 5520A and 5700A Multifunction
Calibrators
The above mentioned calibrators are used primarily for the calibration of indicating
measuring instruments such as multimeters, laboratory recorders, current clamps,
panel
-mount measuring instruments
etc., and include the various electrical quantities
required to this end. By incorporating a separate METRA
Hit (in some cases written
METRAHIT) 18S, 28S, 29S, 30M, X
-TRA, EXTRA or ENERGY precision multimeter
with infrared interface into the calibration sys
tem, automated calibration of buffer
amplifiers,
isolating transformers, measuring transducers and the like can be performed.
The software executes interactive
(DIREKT operating mode) or sequence-
controlled
(TEST operating mode)
setup of the calibrator from the PC via an IEEE488
interface, automatic analysis of measured values entered manually or read in from
the multimeter via an RS
232 port, and documentation and archiving of calibration
results in a calibration report. The program calculates the test uncertainty ratio (TUR)
for each calibration point based upon the calibrators
’ accuracy specifications which
are integrated into the software, or overall measuring uncertainty in accordance with
directive DKD
-3 (WECC 19-1990).
A calibration procedure for the
respective calibration object can be generated and
tested in an uncomplicated fashion. Tested calibration procedures for numerous
multimeters from our current and previous product spectrum are included with the
software.
