4.1 Display and operating elements

All the necessary information and measured
values stored in the instrument’s memory
are shown in the display of 

Media 6 with

LCD

. Although the 

Media 6 with LED

 ver-

sion does not have such a digital display,
important operating conditions are indi-
cated by the LED. 

Three keys are used to operate the differen-
tial pressure meter:

Up key
Down key
Enter key

and a DIL switch with four switches to select
the type of gas and write protection function.

4.1.1 Changing over display mode
for Media 6 with LCD

Press the   key to change over from the
standard display to seven other display
modes.
After 8 seconds or after the message has fin-
ished running across the display, the dis-
play returns automatically to the standard
display. 

O2

e.g. gas name and current tank 
content

P

current differential pressure

MCN

maximum capacity nominal

MCN/R

100 % capacity assigned to 
20 mA signal

SCN

save capacity nominal
geometric capacity up to overflow/
gauge pipe

SCN/R

100 % capacity assigned to 
20 mA signal

UCW

useable capacity work 

P100

maximum differential pressure

PTANK

nominal tank pressure  

Indicated value corresponds to the 
pressure assigned to the density

(liquid)

as per vapor pressure diagram. 
If the calculations for 

MCN

 and

 SCN

 

are based on density

(liquid)

 at 1 bar 

abs, then 1 bar is shown for 

PTANK

.

X-TANK-16 

e.g. tank ID as running text

ERROR

error message displayed auto-
matically when an error occurs
(see section 8 on troubleshooting).

OFF

Special signal on opening the
equalizing valve, I = 3.6 mA
(refer to EB 9527-2, page 7).
