If M2= 4 then S2-D2 LA;
If M1= 1 and M2 = 2
then S1-H1 S2+H2, S2 LA, HA S1;
If M1 = 2 and M2 = 1
then S2-H2 S1+H1, S1 LA, HA S2;
If M1 = 3 and M2 = 2
then S1 S2+H2, S2 LA, HA S1+D1;
If M1 = 2 and M2 = 3
then S1+H1 S2, S1 LA, HA S2+D2;
If M1 = 4 and M2 = 1
then S1 S2–H2, S1–D1 LA, HA S2;
If M1 = 1 and M2 = 4
then S1–H1 S2, S2–D2 LA, HA S1;
If M1 = 3 and M2 = 4
then S1 S2, S2–D2 LA, HA S1+D1;
If M1 = 4 and M2 = 3
then S2 S1, S1–D1 LA, HA S2+D2;
where the minimum deviation (D1 or D2) is 0.5% of the maxi-
mum range value.
Note
Some setup codes are available depending on the model.
Note
When a wrong setup value is confirmed
or a wrong setup code is selected, the con-
troller does not skip to the next setup item
but remains in the current item displaying
a flashing "ERROR" indicator until the pa-
rameter value is changed by the user.
Note
In some circumstances, the user cannot succeed in setting a
parameter to a desired value if the related parameters are not
changed beforehand; e.g. to set a EC high setpoint to 10.0
mS the high alarm must be set to a value greater than 10.0
mS first.
