ELECTRICAL CONNECTIONS
To connect your Hanna meter to a PC use an HI 920010
cable.
Make sure that your meter is switched off and plug the
connectors, one to the meter RS 232C connector and the
other to the serial port of your PC.
If your interface does not fully comply with the RS 232C
standard, wiring could be different.
The GND pin of the interface connector and all the inter-
face signals are optoisolated from the ground of the
instrument, the pH electrode and the temperature sensor.
Before connecting the meter to the computer, consult the
computer manual.
