UM344-2ON-LINE AND OFF-LINE OPERATION

5.1.3.3 Local Pushbutton

Adjusting the damping changes the value of the digital filter’s

Damping Adjustment (Controller

time constant. An installed Digital Meter is recommended

OFF)

for this procedure so that the damping values may be

 

monitored.

 

1. Activate the Pushbutton Damping Mode.

 

Simultaneously press and hold, for 5 seconds or more, the

 

FULLSCALE and ZERO pushbuttons, then release both

 

pushbuttons. Note the following.

 

∙ The Damping Mode is automatically de-activated

 

when a 1 minute "mode active" period times-out. If

 

a change is not made, the present value is retained.

 

∙ When both pushbuttons are pressed a "PB"

 

annunciator will appear on the Digital Meter. If the

 

pushbuttons have been held on for the required

 

minimum 5 seconds, when they are released, the

 

"PB" annunciator will remain on and the Digital

 

Meter will alternately display the letters "SEC" (for

 

seconds) and the present damping value in seconds.

 

2. Select a new damping value. The damping value choices

 

are: 0, 0.5, 1, 2, 5, 10, 20, 30, 60, 90, and 120 seconds.

 

Repeatedly press the ZERO pushbutton to step down or

 

the FULLSCALE pushbutton to step up through the list.

 

Select a time constant from the list that is closest to the

 

desired value.

 

3. Simultaneously press, then release, both pushbuttons. The

 

new value is stored in memory and normal operation is

 

restored.

 

4. Restore protective cover over pushbuttons.

 

5. To set damping without a digital meter activate the

 

pushbutton mode as described in step 1 above.

 

6. Repeatedly press the ZERO pushbutton at least ten times

 

to set the damping value to zero seconds.
