General
This manual explains the function of the SF6Analyzers 973, Version 973-SF6. In this manual the
instrument will be called 973.
Vol SF6 % All descriptions in bold and italic are related to the text on the front
panel, the display and the back panel of the 973.
If you wish to use the instrument as quickly as possible, we recommend reading the chapters
Initial Setup (page 9) and Measurement (page 15). Standard use of the instrument is ex-
plained in these two chapters.

Short Description
Reliable SF6Measurement
The 973 was specifically designed for measurement of Humidity and SF6Purity in gas insulated
switchgear systems. Humidity Measurement data is displayed in ppmv, ppmwand Dew/Frost
Point. Purity Measurement is displayed directly in % Volume SF6. Both the Humidity and Purity
measurements utilize accurate and reliable condensation techniques.
Gas Recovery and Pressure Measurement
The 973 is equipped with a gas recovery system that stores the sampled gas during the meas-
urement process in its internal storage tank. After completion of the measurement, the stored
gas is automatically pumped back into the original compartment or into another vessel. The
compartment pressure is also measured.
Easy, Automated Measurement
The 973 is equipped with a user configurable full color active matrix LCD with integrated touch
screen. The 973 may be configured for measurement of Humidity and % Volume SF6with either
automatic or manually initiated Pump Back. In addition the 973 measures the pressure of the
connected gas compartment. Using the bi-directional RS 232 communications port, all meas-
urement data may be easily transferred into a computer.
Calibration
Easily check the calibration at any time using the built-in Ice Test function, providing instant
proof of system accuracy and integrity.
Connect and Go
The system is supplied ready for immediate use.

LCD Display with Touch Panel
The 973 utilizes a full color active matrix liquid crystal display with an integral touch panel. It has
a high contrast ratio and a wide viewing angle for easy readability. Data is displayed in large
easy to read fonts. Using the on screen function and menu keys, you can easily configure each
line of the display and navigate the menus.

Data Lines
The first four lines of the display are for numeric or graphic representation of the measured data.
We refer to those first four lines as Data Lines. Numeric data lines contain the value to the left,
with the parameter description and units to the right. The displayed parameters and units can be
changed, but after a restart of the instrument the values will be reset to the stored standard con-
figuration.
1. Data Line
This line displays the measured Dew/Frost Point.
The unit is °C related to atmospheric pressure.
2. Data Line
This line displays the humidity content in ppmw
(parts per million weight). This unit is pressure in-
dependent.
3. Data Line
This line displays the SF6purity in % Volume.
4. Data Line
This line indicates the current pressure of the gas
compartment. The unit is kilo pascal absolute pres-
sure.

The data lines indicating the measured Humidity as well as the % Volume SF6will only be dis-
played after completion of the measurement. During the measurement only the current gas
pressure of the measured compartment is indicated.
Fixed Function Keys and Status Line
The bottom line of the display contains two fixed
function keys. By pressing the Start button the
measuring process will be started. With the Pump
button the pump back of the stored gas in the inter-
nal tank can be activated manually. These function
keys are not changeable and are always available.
Additionally this line contains the status indication,
which indicates the current operation mode. The
level indicator of the internal tank indicates the cur-
rent storage capacity.

Menu Keys
To the right side of the display is a column of menu
keys. Each of these keys changes function as nee-
ded.
Notice that the bottom key in this column is different
from the rest. The bottom key is used to cycle the
upper keys through the various menu options. The
text on the bottom key changes to indicate the cur-
rently selected menu option. The text of the upper
keys change based on the functions available in the
menu.
