ACD
If the auto-calibrate option is fitted, every x hours the calibration gas will automatically be fed
to the measuring cell and after a few minutes the analyzer will self calibrate. Acd is set in hours.
Auto calibrating on a weekly basis would mean an Acd of 168 hours. A setting of 0 turns the feature
off.
LIFE
The value shown is an approximation of the operational lifetime left in the cell in percent. A
figure of 50 would mean that half of the life of the cell had been used. If the instrument was in service
for 2 years, then the cell would last for approximately another 2 years
GAS
With some configurations the balance/background gas will have an effect on the calibration of
the analyzer. An instrument set up correctly to measure oxygen in nitrogen will not read correctly on
oxygen in argon. This calibration factor is due to the molecular weight of the background gas.
Setting and changing the gas factor to the correct molecular weight for the background gas will
always make the analyzer read correctly. The table below gives some common molecular weights;
other gas molecular weights can be found from reference books.
GAS
MOLECULAR
WEIGHT
Nitrogen
28.02
Argon
39.91
Helium
4.0
Hydrogen
2.02
Sulphur Hexafluoride
146.0
Ethane
30.07
Ethylene
28.05
Propane
44.0
Methane
16.04
Gas mixture molecular weights can be ascertained by a direct relationship,
i.e. a gas background of 60% helium and 40% argon will be
(0.6 x 4.0) + (0.4 x 39.91) = 2.4 + 15.96 = 18.36
ANCHx
This is used to set the analogue outputs characteristics. This can be either, 4-20mA or 0-
20mA.
Set the output to the table below:
Note that each output is independent and can be set for either output type.
DIGIT
OUTPUT TYPE
0
4-20mA
1
0-20mA
PASS
Used to enter into Page 1 of the programme menu. Here is where all the parameters for
commissioning will be set.
The factory configuration password is 1234. Be sure to make a note should you want to
change the password.
Should the password be lost then the password 1111 will always gain entry.
