• In the setting "LR Linear", the leak rate is calculated as follows:
Leak rate = final value/10x voltage
For example: 10 V refer to the final value, e.g. 10
-3
mbar l/s, then, 3.7 V refer to, e.g.
3.7x10
-4
mbar l/s.
For "Current Lin.", it is similar for current instead of leak rate.
The final value and the increase (volts/decade) have to be set separately in the

for the outputs 1..2 and 3..4.
The increase volts/ decade does not apply for linear values.
5.7 Using the I-Stick and the parameter sets
The I•Stick (Cat-No. 200001997) can be used to save up to 25 parameter sets and
to be able to copy them easily from one device to the other.
A parameter set comprises all settings except the language and the RS232 protocol.
Copying takes place as follows:
1 Go to Main Menu
→
Settings
→
Copy Parameters
2 On the left side, select your required parameter set . You can select between the
options Default Parameter Set, Current Parameter Set, three internal parameter sets
and up to 25 parameter sets on the I•Stick. If no I•Stick is connected, Copy does not
work. If the memory on the I•Stick is empty, the default parameter set will be copied.
3 On the right side, select the destination which the parameter set is to be copied to.
4 Now use "Copy" for copying the parameter set or "Edit name" to copy the parameter
set with a new name to the right side.
5 Before copying, the differences of the parameter sets are displayed from the right
and the left side for confirmation.
6 If copying was successful, you will return to the "Settings" menu, if not, you will
receive an error message and the "Copy Parameter" menu will be displayed again.
