1 INTRODUCTION
Thank you for selecting the Fisher Scientific Accumet AB 30
bench-top meter. This instruction manual describes the operation
of the meter. The state-of-art meter that you have purchased is
easy to operate and will guide you through the various functions
by displaying easy to understand prompts.
This instruction manual is designed to provide all the information
necessary to guide you through the process of measuring pH or
mV with a series of prompts on the screen.

You will find this symbol appearing in this manual; it indicates
useful tips that ease your meter operation.
The Accumet AB30 provides microprocessor precision in a
compact benchtop design that is easy to use. This meter allows
you to:
§Measure conductivity, resistivity and Total Dissolved Solids
(TDS).
§Select cell constants, temperature coefficients, and
temperature units.
§Standardize with two key strikes
§Replatinise your conductivity probe
It all adds up to rapid, completely automatic, intuitive operation.

3 GETTING STARTED
3.1 Connectors
1. Review the layout and arrangement of the rear connector panel.
2. Connect the electrode arm to the base.
3. Connect the power cable to the connector cable to the rear
connector panel power jack and to a power source.
4 USING THE METER
4.1 Conductivity Probes
This meter allows you to use both 2-cell and 4-cell conductivity
probes.
FF
FFDO NOT connect both probes together.
Remove the protective cover from the end of the probe. Prior to
use, soak the probe in distilled or deionized water for 10 minutes.
1. Install the 2-cell probe by plugging the pin connectors into the
dual pin jacks on the back of the meter.
OR
Install the 4-cell probe by plugging in its DIN connector into the
DIN jack on the back of the meter.
Install the ATC probe by plugging the 1/8Ó mini-phone jack into the
ATC jack on the back of the meter.
FF
FF
The Accumet 4-cell probe has built-in ATC and a separate ATC
probe is not required.
2. Rinse the conductivity probe
sensing elements with distilled or
deionized water between samples.
3. For long term storage, the
probes can be stored dry or in distilled
water.
FF
FF
Note that the cell constant may change slightly due to storage or
use, and it must be re-evaluated with the use of standard
conductivity solution (standardization) prior to use.
4.2 Display/ Keys
Overview of the meter screen display and function key layout.
Press std key to initiate
standardization from measure
mode. Or press std key at the
Standardize mode to confirm
the standardization and
return to Measure mode.
Press setup key to access
setup for configuration of
meter setting.
Press _ key to increase value
or scroll up selection.
Press enter key to confirm
selection or change being
made.
Press stdby key to start up or
put the meter in standby
mode.
