5.3 PROGRAMMING AND CALIBRATING THE MODEL XMT
- TUTORIAL
Setting up and calibrating the Model Xmt is easy. The following tutorial
describes how to move around in the programming menus. For practice, the
tutorial also describes how to assign values to the 4 and 20 mA output.
1. If the menu screen (shown at the left) is not already showing, press
MENU. Calibrate is blinking, which means the cursor is on Calibrate.
2. To assign values to the current output, the Program sub-menu must be
open. Press q. The cursor moves to Program (Program blinking.)
Press ENTER. Pressing ENTER opens the Program sub-menu.
3. The Program sub-menu permits the user to configure and assign val-
ues to the 4-20 mA output, to test and trim the output, to change the
type of measurement from what was selected during Quick Start, to set
manual or automatic temperature correction for membrane permeability,
and to set security codes. When the sub-menu opens, Output is blink-
ing, which means the cursor is on Output. Press q or
u (or any arrow
key) to move the cursor around the display. Move the cursor to >> and
press ENTER to cause a second screen with more program items to
appear. There are three screens in the Program sub-menu. Pressing
>> and ENTER in the third screen cause the display to return to the first
screen (Output, Temp, Measurement).
4. For practice, assign values to the 4 and 20 mA output. Move the cursor
to Output and press ENTER.
5. The screen shown at left appears. Test is blinking. Move the cursor to
Range and press ENTER.
6. The screen shown at left appears. + is blinking, which means the cursor
is on +.
a. To toggle between + and - press p or q.
b. To move from one digit to the next, press t or u.
c. To increase or decrease the value of a digit, press p or q.
d. To move the decimal point, press t or u until the cursor is on the
decimal point. Press p to move the decimal to the right. Press q to
move the decimal point to the left.
e. Press ENTER to store the number.
7. The screen shown at left appears. Use this screen to assign a full scale
value to the 20 mA output. Use the arrow keys to change the number to
the desired value. Press ENTER to store the setting.
8. The screen shown at left appears. To configure the output or to test the
output, move the cursor to the appropriate place and press ENTER.
9. To return to the main menu, press MENU. To return to the main display,
press MENU then EXIT, or press EXIT repeatedly until the main display
appears. To return to the previous display, press EXIT.
NOTE
To store values or settings, press ENTER before pressing EXIT.
