MEASURE - ERROR 18:
Different mass conc. Mass concentrations on the
”SUBSTANCES/Calibration”
and ”SOLUTIONS” pages do
not agree
Set mass concentrations equal on both
pages
E/S
MEASURE - ERROR 19:
Missing mass

ADD and CSOLN instructions
− No solution for ADD instruc-
tion specified
− Enter Mass conc. on the
”SUBSTANCES/Calibration” page
− Enter solution name Soln.name in
ADD instruction

MEASURE - ERROR 20:
Illegal instruction for
Autosampler The SMPL/M and CSOLN/M
instructions are not allowed
with the 695 Autosampler
Correct SMPL or CSOLN instructions on
the ”OP.SEQUENCE” or ”SEGMENTS”
page

MEASURE - ERROR 21:
V.sample max too small
for dosing The maximum volume
V.sample max of the sample
vessels on the sample rack is
too small for the volume to be
dispensed
Lower volume V.add for dispensing or
transfer instruction
E/S
MEASURE - ERROR 22:
Unknown volume in FEED
for dosing − The entry of the asterisk in
Sample size/S0 is here not
admissible in conjunction
with the SMPL/F instruction
− The entry of the asterisk in
V0.CSoln. is here not ad-
missible in conjunction with
the CSOLN/F instruction
− Enter volume or mass in Sample
size/S0
− Enter volume in V0.Csoln.
E/S
MEASURE - ERROR 23:
Illegal * in
calibration volume
V0.CSoln. The entry of the asterisk in
V0.CSoln. is not admissible in
operation without the 695
Autosampler
Enter volume in V0.CSoln. E/S
MEASURE - ERROR 24:
Illegal variable S2 No numeric value in S2 . If S0
has been entered as the mass,
the density must be entered in
S2 in g/mL
Enter density in g/mL in S2 on the
”SAMPLES” page
E/N
MEASURE - ERROR 25:
Undefined electrode Undefined electrode type
(electrode type must be
entered before the measure-
ment mode)
Enter instruction for the electrode type
before that for the measurement mode
on the ”OP.SEQUENCE” or
”SEGMENTS” page
E/S
MEASURE - ERROR 26:
Undefined measurement
mode − Undefined measurement
mode (measurement mode
must be entered before the
sweep)
− Wrong measurement mode
(e.g. CYCMODE with SWEEP )
− Enter instruction for the measurement
mode before that for the sweep on
the ”OP.SEQUENCE” or
”SEGMENTS” page
− Enter correct measurement mode on
the ”OP.SEQUENCE” or
”SEGMENTS” page
E/S
MEASURE - ERROR 27:
Too many measuring
points The maximum number of 1000
measured points for a sweep
was exceeded
Reduce number of measured points by
shortening the sweep ( U.start/U.end )
or increase the voltage step U.step

MEASURE - ERROR 28:
Missing (CSWEEP Command for start of the cyclic
loop missing
Enter instruction (CSWEEP on the
”OP.SEQUENCE” or ”SEGMENTS”
page
