4.4.4.3. Viewing and Checking Channel Data Logger Page  

 

When viewing the contents of a channel data logger page, the data table has the 

same view as in the figure 4.16. The table contains the channel number, name and 
frequency, and also the measured parameters. If any errors are found in the channel 
parameter values, this channel number will be shown against the red background.  

If the current channel is digital, the 

dig

 value will be shown in V/A parameter field. 

Dashes in the value field mean that this parameter measurement is not measured for this 
type of channel. Empty field means that this parameter measurement is turned off in the 
channel plan. 

 

Figure 4.16 

 

The following commands can be accessed  by the functional keys: 

1. 

Info

.  Select by 

F1

. Viewing of the detailed channel data. 

2. 

Graph

.  Select by 

F2

. Viewing of the table in Scan mode. 

3. 

Run

. Select by 

F3

. Scanning of the channel data logger page. 

To identify the errors after the limit test, open the table of the detailed channel data 

(

F1 

key). The test  parameter table will appear on the screen (figure 4.17).  

 

Figure 4.17 

 

In this table you can see the parameters for the measured data to be verified with 

according to the limit plan, and also the measured parameters. The parameter value field 
is highlighted in red if it failed the limit test. The value will not be shown in case the 
parameter is disabled for measurement in channel plan. The limit fields will show OFF if 
the parameter is disabled in limit test. 

Using 

 

and 

keys you can scroll through the channels without exiting the test 

parameter table. To switch between the channels with errors, use 

F2

 and 

F3

 keys.
