5.2 Printing out measured values

24 826/827 pH meter, Instructions for Use

adapted accordingly, as otherwise the buffer memory of the con-

nected printer would be filled too quickly. This means, for exam-

ple, that the report header should only be printed out once at the

start of a series of measurements. Otherwise data could be lost.

In this case you should consider matching the measured value

recording to the measured value memory (see Section 5.3).

stop time: 0...999'999 s

The time after which an automatic series of measurements is to

be terminated can be entered in whole seconds. You can also let

a series of measurements run indefinitely without a fixed stop time

and then stop it manually with <QUIT> if you select the default

value'0 s' for this setting.

print crit.: drift

If this print criterion is used, a measured value will be printed out after

pressing <OK> in the menu print not until the message

drift-

ing... is no longer displayed.

date & time: on, off

rep.header: once, always, off

cal.report: on, off

These settings correspond to those of the print criterion 'immed.'

(see above).

print crit.: change

The next measured value is printed automatically not until the difference

to the previous measured value is bigger than the parameter delta

pH/T/mV defined here.

date & time: on, off

rep.header: once, always, off

cal.report: on, off

These settings correspond to those of the print criterion 'immed.'

(see above).

delta pH: 0.10...0.50...16.00 pH

delta T: 0.1...0.5...100.0 °C

delta mV: 0.1...30.0...999.9 mV

stop time: 0...999'999 s

The printout of the measured values is terminated when the stop

time has elapsed or will continue indefinitely ('0 s'). A termination

is always possible with <QUIT>.
