EGM-5 Operation Manual V. 1.04

support@ppsystems.com

Splash Screen

The Splash screen is always shown on the display when the EGM-5 is off. When the instrument is first
powered up, the Splash screen is displayed momentarily followed by the Measure screen displaying CO

2

in large text.

Measurement Mode

The Measurement Mode is comprised of four screens:

1.  Measure screen
2.  Readings screen
3.  Probe screen
4.  Graphic display screen

Each screen allows the user to view the EGM-5 data in various ways. The screens can be rotated through
by the user using the left (< -) and right (- >) arrow buttons. Generally speaking, the left arrow brings you
back to the previous screen and the right arrow to the next available screen. The initial screen is the
Measure screen which displays the value of CO

2

concentration in a large bold font. The next screen is the

Readings screen and displays the values of six parameters in real time; CO

2

, H

2

O, O

2

, Temperature, Flow

Rate, and Pressure. The third screen is the Probe screen which displays the values of six parameters in
real time; CO

2

, PAR, Aux, air temperature (Tair), soil temperature (Tsoil) and soil moisture (Msoil). The

fourth screen Graphic Display screen which displays CO

2

, H

2

O or O

2

concentration graphically over time.

Each screen contains common features. There is a flashing

♥

icon to confirm that the EGM-5 is on

(power status). The percentage value in the top left corner is the percentage of battery remaining. The
percentage value in the top right corner is the percentage of absorber column remaining. Also, a manual
zero can be initiated using the “Z” button. A status or error message can be displayed in the Status Box.
Each Measurement screen is explained in more detail below.

Measure Screen

The Measure screen is displayed after the Splash screen once the EGM-5 is powered up. For the first 10-
15 minutes, the EGM-5 goes into a warm-up period until it achieves its final temperature of 55°C and a
zero check is performed. During this time, messages are displayed in the Status Box that indicate that the
instrument is in the warm-up stage (see below). During warm-up, the CO

2

value is displayed as 0 ppm.
