OPERATIONAL GUIDE
•
The meter is supplied complete with four 1.5V AA
alkaline batteries. Remove the cover, unwrap the bat-
teries and install them while paying attention to their
polarity (also see “Battery Replacement” section).
•
To prepare the instrument for use, connect pH elec-
trode and temperature probe to the BNC and tem-
perature sockets on the top of the instrument.
•
The temperature probe is used in conjunction with the
pH electrode to utilize the meter’s ATC capability, but
it can also be used independently to take temperature
measurements. If the probe is disconnected, the tem-
perature can be set manually using the arrow keys
(see page 13 for details).
