interface (6.2148.010) (see Section 9.5). Out of limits conditions are al-
so shown on the display and documented in the report.
state: ON, OFF
u.limit -1.00E+30...1.00E+30
u.hyst. -1.00E+30...2.00...1.00E+30
l.limit -1.00E+30...0.00...1.00E+30
l.hyst. -1.00E+30...2.00...1.00E+30
The exact way in which the limits function works is described in Sec-
tion 7.4 independent of the mode.
6.5.7 Limits T
(applies only for Conc measurement type: direct)
PARAMETER Conc
:
├ limits T
: └ state
Just as in the pH mode, in the Conc mode the temperature can also be
monitored via the limits function in addition to the primary measuring
quantities. However, you should only activate this limits function for the
temperature when a temperature sensor is connected, as otherwise an
error message will appear.
state: ON, OFF
u.limit -999.9...100.0...999.9 °C
u.hyst. -999.9...0.2...999.9 °C
l.limit -999.9...0.0...999.9 °C
l.hyst. -999.9...0.2...999.9 °C
A detailed description of the remote lines is given in Section 9.5. The
exact way in which the limits function works is described in Section 7.4
independent of the mode.
6.5.8 Plot parameters
(applies only to measurement type: direct)
PARAMETER Conc
:
├ plot parameters
: ├ left mar.
├ right mar.
├ left marg.T
└ right marg.T
The directly measured quantities concentration and temperature can be
printed out as a function of time in a plot. Under
CONFIG/print meas.
value
the print criterion 'plot' must be selected (see Section 5.2).
The scales of the measured values axes are determined by the follow-
ing limits.
