Introduction
Thank you for purchasing the Fisherbrand™accumet™
AB330 conductivity bench meter. The accumet AB300
meters are designed to provide the important functions
needed for routine measurements with simplified,
convenient, easy-to-use functionality.
The accumet AB330 conductivity meters are capable of
measuring conductivity, salinity, TDS and temperature and
offer a large, backlit display for clear viewing with small
footprint to conserve laboratory bench space.
Ensure important data is preserved with a 500-point data
log with date/time stamp that can also be exported to a
printer or computer using the meter communication port.
All accumet AB330 conductivity meters include a meter-
attached electrode holder and universal 100-240V power
adapter with wall plugs for US/Japan, Euro, UK/Singapore,
Australia/New Zealand and China. Additional meter
accessories can be viewed at www.fishersci.com.

Getting Started
2.1 Electrode Holder
Installation
The meter-attached electrode holder (Catalog Number 13-
637-671) can be installed on either side of the meter.
Unpack the base plate and stand with electrode
holder from the meter box.
Turn the meter over, with the meter display facing
down, on a clean dry surface.
Identify the side of the meter that the holder will be
installed on and remove the screw between the
circles on that side of the meter.
Align the base plate of the holder with the circles
on the meter.
Replace the screw from step 3 to attach the base
plate to the meter.
Turn the meter over, with meter display facing up.
Insert the stand with electrode holder into the
metal post on the base plate.
Place the electrodes into the electrode holder.
2.2 Universal Power
Supply Assembly
A universal power adapter (Catalog Number 13-637-010)
with US/Japan, Euro, UK/Singapore, Australia/New
Zealand and China wall plug plates is included with the
meter. This universal power adapter is specifically for use
with this meter. Use of other power adapters can damage
the meter and will void the warranty.
Unpack the power supply provided with the meter.
Select the appropriate wall plug plate for the
power outlet that will be used.
Slide the appropriate wall plug plate into the
groove on the back of the power adapter.
Connect the assembled power adapter to a power
outlet and meter input.
a. To connect the power adapter with the meter,
insert the power adapter plug and twist to lock
the connection.
Note: The power adapter plug has two prongs that allow
the power adapter to be locked onto the meter. These two
prongs must be properly aligned when connecting it to
ensure it is fully connected and locked onto the meter.
You are now ready to turn on the meter.
CAUTION: Use of a surge protector or
uninterrupted power supply (UPS) is
recommended, as an unintended power
surge of electricity to the meter may
damage the meter and void the warranty.
