Introduction

822 Titration Curve Simulator, Instructions for Use

1 Introduction

These Instructions for Use give you a overview of the applications and

the functionality of the 822 Titration Curve Simulator.

First, the device as such and the simulation of the titration curves are

explained. The description of the additional curves, the explanation of

the LEDs and the technical data are summarized in the appendix.

1.1 Instrument

description

The 822 Titration Curve Simulator is a diagnostic tool that allows

Metrohm service technicians to check titrators. With this simulator a

possible malfunction of the titration or dosing device or even the elec-

trode can be identified quickly and easily. This is done by connecting

the 822 Titration Curve Simulator instead of an electrode. During the

test it simulates a titration, i.e. the user gets a titration curve without us-

ing electrodes or chemicals.
