In order to protect the instrument and the components connected to it from unqualified hand-
ling, the above mentioned procedure has to be performed. In addition, the instrument configura-
tion can be protected by a 4-digit PIN. This PIN is factory set to 0000, which means that after
pressing the SCROLL button for 2 s, properties can be changed freely. The Windows software
BMT 932 Link can be used to change this PIN to any other 4-digit number. If the PIN is differ-
ent from 0000, pressing the SCROLL key for 2 s will lead to the display of:
Enter PIN 0000:
Only the correct PIN will allow entry to Set Parameters, any other number will lead back to the
display of ozone concentration. The PIN is entered digit by digit, by using the SET key to
change digits and using the ENTER key to move from one digit to another and finishing PIN
entry.
