fix EP1 at pH OFF

pK/HNP: OFF

Interpolation of volumes at fixed times (input range

depends on the measured quantity:

pH:

0...±20.00, OFF

U, Ipol:

0...±2000 mV, OFF

Upol:

0...±200.0 uA, OFF)

sets "OFF".

If a fix end point has been set, the volume value for the

input measured value is interpolated from the curve,

see also page 23. The volume values are available as

C5X.

Fix EP's are inquired until "OFF" is set. Up to 9 fix EP's.

Evaluation of pK or HNP (ON, OFF)

pK evaluation in case of pH titrations and half

neutralization potential for U, see page 23.

Preselections for the sequence

Request of identifications after start of titration. (id1,

id1&2, all, OFF)

After start, sample identifications can be inquired

automatically: Only id1, id1 & id2, all three id's or no

inquiries.

Request of sample size after start of titration (value, unit,

all, OFF)

"all" requests the value, then the unit.

Limiting value check for sample size (ON, OFF)

With "on" the error message "sample size out." appears

if the entry is outside the set limits. The limiting values

are shown in the display window.

The absolute value of the limit is checked during sam-

ple size input and during the calculation of the results.

If "on" has been set:

Lower limit for sample size (0.0...999 999)

Upper limit for sample size (0.0...999 999)

Pulse output on I/O line "activate" (L6, pin 1) of the

remote socket (ON, OFF)

see page 166.
