1.2 Controls and parts
794 Basic Titrino
5
6 RS232 interface
for the connection of printer, balance or a computer
7 Remote lines
(input/output)
for the connection of the Remote Box, Sample Changers, robots etc.
8 Connection of electrodes and temperature sensor
• 2 high-impedance measuring inputs for pH and U measurements (Ind I/ Ind II).
They can either be used separately or for differential potentiometry, see page
155.
Important: If you work with both measuring inputs in the same vessel, the same
reference electrode must be used.
• 1 measuring input for polarized electrodes (Pol).
• 1 measuring input for PT100 or Pt1000 temperature sensor.
9 Connection for separate keypad
10 Analog output for the connection of a recorder
11 Connection for power cable
With power supplies where the voltage is subject to severe HF disturbances, the Ti-
trino should be operated via an additional power filter, e.g. Metrohm 615 model.
12 Mains switch
13 Earthing socket
14 Connection for stirrer
728 Magnetic Stirrer, 802 Rod Stirrer, 703 or 727 Ti Stand
Supply voltage: 9 VDC (I ≤ 200 mA)
15 Display of the set mains voltage
Before switching on for the first time, check that the set mains voltage matches the
voltage of your power supply. If this is not the case, disconnect mains cable and
change voltage.
16 Rating plate
with fabrication, series and instrument number
