GENERAL OPERA

TIONS

After the initialization has been completed if the probe is connected, the meter displays the Probe 
Status screen. The probe status screen identifies the probe and attached sensors.

Press 

Measure

 to view the measurement screen. 

Log

 and 

Menu

 functional keys are displayed.

Press 

Param.

 to open the Parameters menu. This screen can also be accessed from the main menu.

Press the down arrow key to view additional information about the probe.

6.4.  BASIC OPERATIONS

The main operating modes are setup, measurement and logging.
The instrument can be configured to display measurement data for all enabled parameters (up to 11). 
The display has a feature that automatically sizes the digits to fit the screen. With fewer measurements 
the digits will be largest.

 

 

Press the keys on the alphanumeric keypad (1 - 7) to select number of parameters displayed at one 
time.
Use the arrow keys to scroll through the enabled parameters if they do not fit on one screen.

Note:

 Pressing 7 will display up to 11 parameters simultaneously.

Press 

Log

 to display the Log menu. Log a single sample or start an interval log. See LOGGING section 

for detailed description.
Press 

Menu

 to select the measurement parameters (see PARAMETER SETUP section).

To calibrate the sensors, see CALIBRATION section.
To change system settings, see SYSTEM SETUP section.
To view the meter and probe status or GLP information, see STATUS section.
