Multi-channel unit:
Press the key to enter the SELECT COM-
PONENT menu to change the settings for a
different channel.
Note for multi-channel units:
Valves can be freely assigned to channels.
This includes among others the following
variations:
• identical combinations (of zero and span
gas valves) for several channels
• Combinations in which one valve has the
same function for several channels
•
Combinations in which one valve has a dif-
ferent function depending on the channel;
e.g. a zero gas valve for channel 1 is also
the span gas valve for channel 2.
Depending on the gases use, the calibration
procedure can be optimised for time or efci-
ency using such combinations.
