780/781 pH/Ion Meter, Manual
print crit.: drift
If this print criterion is used then a measured value will only be docu-
mented when the drift condition defined under PARAMETERS/measur-
ing parameters/drift has been fulfilled.
date & time: ON, OFF
report header: once, always, OFF
calibration report: ON, OFF
These settings correspond to those of the print criterion
' immediate ' (see above).
print crit.: plot
The directly recorded values can be outputted graphically as a meas-
ured value/ time plot.
time interval: 0.1...4...99999.0 s
In a similar way to the print criterion 'time' a time interval can be
defined for graphical measured value recording.
time scale: 5,10,30,60,120,180..99960 s/cm
This is the time axis scale. The reciprocal value of the quantity en-
tered corresponds to the paper feed rate. This means that, e.g.,
for a required feed rate of 2 cm/min a time scale of ½ min/cm =
30 s/cm must be entered.
time scale label.: rel, abs
The time axis scale can use the relative time in minutes and sec-
onds (start = 0 s). The current time can also be used with ' abs '.
stop time: OFF, 1...999999 s
The graphical plot is terminated when the stop time has elapsed
or will continue indefinitely (' OFF '). In both cases termination is
possible with <QUIT>.
