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.

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.

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.

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.

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.
