Introduction

About this Manual

This manual provides detailed instructions for setup, operation and
maintenance of the Multi-PID 2 Portable Photoionization Monitor.

Before unpacking the instrument, please read Warnings and Safety
Practices. This section describes possible hazards that might injure
the user, damage the instrument or compromise its operation. Some
general safety information is also provided.

To help you learn to use the Multi-PID 2 quickly, this manual is organi-
zed by tasks beginning with:
—

Using the Multi-PID 2 in “Using the Multi-PID 2” on page 25..

—

Accessories are covered in “Connecting Accessories” on
page 43..

—

Routine maintenance is covered in “Routine Maintenance” on
page 71..

—

Troubleshooting techniques are covered in “Troubleshooting” on
page 87..

The Multi-PID 2 manual uses a few conventions for key names on the
keypad and for text that is shown on the display.

» Display Text «

Texts shown on the Multi-PID 2 display are written with quotation
marks, e.g.

» Enter current time «

The names of soft keys are also written with quotation marks, e.g.

" select "

In the text you will ﬁnd various warnings and notes.

WARNING:
A warning indicates an operation that could cause
personal injury if precautions are not followed.

CAUTION:
