When configuration of the instrument is completed, most
parameters will not need to be set by field operators.
Furthermore, field operators may not understand many
parameters, and may probably set parameters incorrectly
by mistake and make the instrument unable to work.
EP1~EP12 define 0~12 field parameters for operators' use
in parameter table. Their parameter values are parameters
except parameter EP itself, like H.AL1, L.AL1, .etc,
Parameters from EP1 to EP12 can define 12 field
parameters at most, if the number of field parameters is
Field
less than 12(sometimes even none), it is necessary to
EP1-12
NonE~bAud
parameter
define field parameters from EP1 to EP12 in order, the first
unused EP should be set to none.
For example, six parameters of H.AL1 to H.AL6 (all
channels' upper alarm) are need to be modified by field
operators, the parameter EP can be set as following:
EP1=H.AL1、EP2=H.AL2、EP3=H.AL3、EP4=H.AL4 、
EP5=H.AL5 、EP6=H.AL6 、EP7=nonE
Sometimes field parameters are not needed after we finish
adjusting the instrument, we can set EP1 parameter an
nonE, then set Loc to 0 or 1.
