1. From the Output Setup menu, select Current Out.
2. A new menu opens with 2 options: I/O Mode and Cal. frozen.
In the later you can toggle between the options Cal. frozen and Cal. active to determine the
behavior of the current output during calibration:
• Cal. frozen: freezes the current output to the last value before calibration in order to avoid
unnecessary jumps during e.g. the logging of the current values.
• Cal. active: shows the actual current output during calibration.
The current output settings are, however, found under I/O Mode. Clicking <ENTER> after high-
lighting it opens the menu where the different current output modes can be adjusted.
3. Press <ENTER> on the first display line successively until you reach the desired current output
mode (see Table 6.2).
4. Changing the signal’s source: from the second display line where usually Ch. 5 is shown,
the source of the current signal can be changed. To change the channel, click <ENTER> key
multiple times to toggle through the channels until you reach the desired channel (see Table 6.1
for the typical assignment of the channels). The gas measured by thermal conductivity is routed
to channel 5 (displayed as e.g. Ch5. H2 for hydrogen).
5. Changing the value of the constant output: in case you chose the Const. Outp. mode, you
can manually change the value of the constant current output by moving the cursor to the second
display line Const. I-Out, clicking <ENTER>, and entering the desired value followed by clicking
OK (see Figure 6.6).
If you are not using the current output, it can be set to a constant value of 0.
