16) HOUR : to set the current hour. Use the arrows to modify this parameter and confirm using
ENTER.
17) MIN : to set the current minutes. In order to correctly synchronize the minute, it is possible
to reset the seconds by pressing the °C/°F key. Use the arrows to set the current minute plus
one, and as soon as that minute is reached press °C/°F: this synchronizes the time to the
second. Press ENTER to go onto the next item.
18) BAUD_RATE: indicates the frequency used for the serial communication with the PC.
Values from 1200 to 38400 baud. Use the arrows to modify this parameter and confirm us-
ing ENTER.
The communication between instrument and PC (or serial port printer)
only works if the instrument and PC baud rates are the same . If the USB connection is
used this parameter value is automatically set (please see the details on page 30).
FUNC key
It enables the display and logging of the maximum (MAX), minimum (MIN) and average (AVG)
value of the conductivity, liquid resistivity, total dissolved solids, salinity and temperature meas-
urements, updating them with the acquisition of new samples. The acquisition frequency is once a
second. Use the
χ
- Ω -TDS key to switch from conductivity to liquid resistivity, to total dissolved
solids or to salinity.
MAX, MIN and AVG measurements remain in the memory until the instrument is on, even after
exiting the calculation function. To reset the previous values and restart with a new measure-
ment session, press FUNC until the message "FUNC CLR" appears, then use the arrows to se-
lect YES and confirm using ENTER.
The conductivity (or resistivity or total dissolved solids or salinity) and temperature values
are displayed at the same time. According to settings in the "RCD Mode" menu item, the
maximum, minimum and average indications have different meanings: please see the descrip-
tion of this MENU key.
Attention: the data captured using the Record function cannot be transferred to the PC
.
ESC key
In the menu, the key clears or cancels the active function (ESC).
CAL key
