Function No. ‘7.’: Sets high limit of the output range

Sets a high limit density value (g/cm

) of an analog output range.

(Note) Difference between high and low limit value should be 0.05 g/cm3 or more. If an

inadequate value is set, the function No. returns to ‘6.’ operations of ‘6.’ and ‘7.’ are related;
when setting is made at ‘6.’ setting should also be made at ‘7.’.

Function No. ‘8.’: Sets reference temperature of measuring liquid

Sets a reference temperature (°C) of measuring solution.

Function No. ‘9.’: Sets temperature coeffi cient of measuring liquid

Sets the value which is -1 x 10

(= -100000) times the temperature coeffi cient of measuring

solution (g/cm

/°C) to change it to plus integer.

(Note) Purifi ed water is an exception; its maximum density is at approx. 4 °C.

Generally, temperature coeffi cients of any liquids are minus number.

Function No. ‘A.’: Sets detector constant A

Sets the detector constant A. Since the detector constant A is an inherent characteristic of the
detector, this is indicated in each detector.

(Note) Detector constant A changes with each calibration.

Function No. ‘B.’: Sets detector constant B

Sets the detector constant B. Since the detector constant B is also an inherent characteristic of
the detector, this is indicated in each detector.

Function No. ‘C.’: Displays detector calibration coeffi cient C (span)

Indicates either the one-point or two-point calibration has been performed. 1 is indicated for one-
point calibration and calibration coeffi cient (span) for twopoint.

Function No. ‘D.’: Displays detector calibration coeffi cient D (zero)

Indicates either the one-point or two-point calibration has been performed. 0 is displayed for
one-point calibration, and calibration coeffi cient (zero point) than 0 is displayed for two-point
calibration.
