Chapter 3. Operation

3.5 Taking Measurements

The Model XGM868i is capable of displaying several different variables in a variety of formats. However, this manual 
will discuss only the basic measurement displays using the LCD display or the PanaView display. Refer to Chapter 2, 

Displaying Data

, in the 

Programming Manual

 for instructions on setting up alternate choices. Also, refer to the 

Programming Manual

 and/or the 

PanaView User’s Manual

 to use PanaView or the analog outputs to obtain the flow 

rate data.

3.5.1 Programming the LCD

Note:

When you first initialize the XGM868i, the number of LCD parameters is set to OFF. You must program the 
LCD to display any measured parameters. 

Through the 

Keypad Program

, you can program the LCD display to display up to four variables in sequence. Complete 

the following steps to program the LCD display:

1.

Power up the XGM868i and wait until it has initialized.

2.

Press 

[Escape], [Enter], [Escape].

3.

In the 

Keypad Program

 window, scroll to 

PROG

 and press 

[

Enter].

4.

In the 

PROG

 

menu, scroll to 

GLOBL 

and press 

[Enter].

5.

Scroll to 

I/O

 and press 

[Enter].

6.

Scroll to

 

LCD

 

and press 

[Enter].

7.

The window now asks for the

 # of LCD Parameters

. Scroll to the desired number (from 

OFF

 through 1-4 and

 KEY

) 

and press 

[Enter]

.

The

 OFF

 setting switches the measurement display off, while the 

KEY

 setting enables users to change the measurement 

display via the arrow keys, without accessing the

 Keypad Program.

 If you select 

KEY:

•

To view a parameter other than the one currently displayed, press the [

] or [

] keys to scroll through the various 

parameters. 

•

To scroll through the channel options on a two-channel XGM868i, press the [

] and [

] keys until you have 

reached the desired option.

For a 1-Channel XGM868i, the data for Channel 1 is displayed automatically, and you can skip to step 9. However, for 
a 2-Channel meter, the channel data to be displayed must be specified at the following prompt.
