1 Introduction

1.1 Description

The Power Box is used to provide the 899 Coulometer with an uninterrup­tible power supply in environments with an unstable or non-existent
mains supply. For instance, you can connect the Power Box to the mains
supply and the 899 Coulometer to the Power Box. If the mains supply fails
while operating the 899 Coulometer, the Power Box automatically starts
supplying power. If you are working completely without a mains supply,
you can operate the 899 Coulometer for at least twelve hours using a
fully-charged Power Box.

1.2 Intended use

The Power Box is intended solely for supplying the 899 Coulometer with
power. No other instruments may be connected to the Power Box.
