Press Save to keep the calibration.
9
Press EXIT to reject the calibration.
4.10 A utomatic buffer recognition
The meter features automatic pH buffer recognition for the predefined buffer groups (see "Appen-
dix") and the user-defined buffer groups. The buffers within a buffer group are automatically recog-
nized by the meter and displayed during calibration.
This feature allows the calibration in any order within a predefined or user-defined pH buffer group.
4.11 S ample measurements
●
Place the sensor in the sample and press READ to start a measurement.
•
The display shows the readings of the sample.
•
The endpoint format blinks, indicating a measurement is in progress.
As soon as the measurement is stable according to the selected stability criterion, the Stability
icon appears.
●
If the "automatic endpoint" format is selected, the measurement stops automatically as soon
as the Stability icon appears.
●
If the "manual endpoint" format is selected, press READ to manually stop the measurement.
●
If the "timed endpoint" format is selected, the measurement stops after the preset time.
4.12 D ata transfer
It is possible to transfer either all data or a user-defined set of data from the memory to a METTLER
TOLEDO printer (for example RS-P26), to a PC by using LabX direct or to a USB memory stick.
The following section describes how to proceed with the different configurations.
Data transfer from the meter to a printer
1
Connect the RS232 cable to the meter and the corresponding interface on the backside of the
print e r.
2
Select the interface "printer" in the data transfer settings menu (see "Setup: Data Transfer Set-
tings").
3
Start transfer in the data menu.
For some printers (e.g. RS-P25, RS-P26 and RS-P28), the baud rate settings will be automatically
syn c hro n ized with those of the instrument.
For other printers the settings for data transfer in the printer need to be adjusted as follows:
●
Baud rate: 1200
●
Data bits: 8
●
Parity: none
●
Stop bits: 1
Data transfer from the meter to LabX direct pH
1
Connect the instrument via USB B to the PC.
The icon appears on the display.
2
Select the interface "LabX direct" in the data transfer settings menu (see "Setup: Data Trans-
fer Set t ings").
3
Open LabX direct pH and select the correct instrument.
