Connecting the AC/DC Adapter
Besides using four AAA-sized batteries as a power source, the pH 11/110 meter can
also operate from the power mains using an AC/DC power adapter either at 120/220
VAC (sold separately). This is extremely useful if you have an A.C. power source
available (e.g. laboratory).
Before plugging in, switch off the meter and the power source of adapter. This is a
safety precaution that should be adhered to safeguard your meter.
1.
Switch off the meter and power sources.
2.
Select the correct AC/DC Adapter either at 120/220 VAC which matches your
input mains voltage.
3. Select the correct output voltage of the AC/DC adapter. (Output Voltage: 9 to
15 V DC, Current: >=50 mA).
4.
Gently insert the power adapter D.C. jack into the meter power socket.
5.
Switch on the power source of the adapter followed by the meter.

Connecting the RS232C Cable (Only for pH 110)
The pH 110 meter provides a RS232C output for you to
transmit your readings either to a printer or a computer via
a cable. This is useful in instances where the meter is used
for continuous monitoring of a certain process or
experiment. Data output to the printer or the computer can
then be evaluated.
The data is output in the ASCII format. This format allows
the data to be imported by a wide variety of software that
read ASCII data (e.g. Microsoft’s Excel, Lotus, Quattro-pro
etc.). A complimentary Data Acquisition Software (DAS) is
provided and it captures data transmitted into an ASCII
file for later use.
1.
Open the printer port cover located at the bottom
end of the meter. Do not use excessive force when doing this. See Figure 10.
2. Noting the orientation of the RS232C connector, plug the male connector into
the RS232C port of the meter.
3. Fasten the RS232C connector by fastening the two screws at the side of the
male RS232C connector.
