Preparing the Meter Section 2
YSI, Incorporated Model 30/30M 4
NOTE: It is very important that the batteries be installed ONLY as illustrated. The instrument
will not function if the batteries are installed incorrectly.
Turn the instrument on by pressing and releasing the ON/OFF key on the front of the instrument.
The liquid crystal display (LCD) should come on. Allow a few seconds for the instrument to
complete its diagnostic routine. Notice that the instrument will display the specific cell constant of
the probe at the completion of its diagnostic routine. If the instrument does not operate, consult
Section 9, Troubleshooting.
You may also want to take the instrument into a dark room and, with the instrument ON, hold down
the LIGHT key. The instrument back-light should illuminate the LCD so that the display can be
easily read.
2.4 STORAGE CHAMBER
The Model 30 has a convenient storage chamber built into the instrument’s side. This chamber
provides an ideal storage area for the probe during transport and extended non-use.
An optional sponge is available from YSI that will fit inside the storage chamber and provide a moist
environment for probe storage should your application or operational procedures require it. See
Appendix B, Accessories and Replacement Parts.
2.5 HAND STRAP
The hand strap is designed to allow comfortable operation of
the Model 30 with minimum effort. If the hand strap is
adjusted correctly, it is unlikely that the instrument will be
easily dropped or bumped from your hand.
To adjust the hand strap on the back of the meter, unsnap the
leather cover and pull the two Velcro strips apart. Place your
hand between the meter and the strap and adjust the strap length so that your hand is snugly held in
place. Press the two Velcro strips back together and snap the leather cover back into place.

2.6 THE METER CASE
The meter case is sealed at the factory and is not intended to be opened, except by authorized service
technicians. Do not attempt to separate the two halves of the meter case as this may damage the
instrument, break the water-proof seal and may void the manufacturer's warranty.
