3.11.14 Activating the backlight
To  activate  the  backlight,  press LIGHT. 
The  default  duration  of  the  backlight  is  6 
seconds, but you can set it between 4 and 
60 seconds in one second increments. 
The  backlight  is  not  available  when  the 
BATTERY CHANGE warning appears.
3.11.15 Diving with MB levels
Microbubbles  are  tiny  bubbles  that  can 
build  up  inside  a  diver’s  body  during  any 
dive  and  normally  dissipate  naturally 
during an  ascent and on the surface  after 
a  dive.  Dives  within  no-stop  time  and 
observance  of  decompression  stops  do 
not prevent the formation of microbubbles 
in  the  venous  blood  circulation.  Meridian 
has  been  equipped  with  an  enhanced 
SCUBAPRO  algorithm,  named  ZH-L8 
ADT MB, to reduce the formation of these 
microbubbles. 
This  enhanced  algorithm  allows  the  user 
to  choose  a  level  of  conservatism  over 
and  in  addition  to  the  worldwide  proven 
safety  record  of  the  standard  ZH-L8  ADT 
algorithm.  There  are  five  levels  of  added 
conservatism (or MB levels), from L1 to L5, 
with  L5  being  the  most  conservative  and 
L1 being just a bit more conservative than 
the  standard  ZH-L8  ADT,  here  referred  to 
as L0.
Choosing an MB level between L1 and L5 
makes  the  algorithm  more  conservative, 
therefore  the  diver  will  have  either  shorter 
no-stop  times  or  deeper  and  longer 
decompression  stops (referred  to  as 
level  stops)  than  when  diving  with  L0. 
Consequently the  body  will either  take  up 
less nitrogen (shorter no-stop dives) or will 
be able to off-gas more before returning to 
the  surface  (dives  with  level  stops).  Both 
work  towards  reducing  the  amount  of 
microbubbles  present  in  the  body  at  the 
end of the dive. 
Please refer to  chapter  3.3.3 Setting the
Micro Bubble level for information  on 
setting the MB level.

  • Hi. What is error message E37 on the Meridian. Just did a dive and computer would not go into dive mode. When I came out it said E 37 Submitted on 27-4-2024 at 12:45
