For step and ramp operation, the percent keys can be 
used to set the milliamp output to 0 % of span, 100 % of 
span, or step the output by 25 % of span. 

Hands-free operation is possible with . Set the 
Product to automatically and continuously step or ramp 
the milliamp output from 0 % to 100 % and back. 

The 100 % value is always 20 mA, but the 0 % value can 
be 0 mA or 4 mA. This depends on how the mA span is 
set. The 25 % step size is 5 mA or 4 mA accordingly. 

To use the manual step function: 

1.  Use the Main menu to set the Product to source or 

simulate current. 

2. Push 



 to set the output to 0 % of span. 

3. Push 



 to set the output to 100 % of span. 

4. Push 



 to step the output in 25 % of span 

increments, from 0 % of span to 100 % of span and 
back. 

To use the automatic step and automatic ramp functions: 

1.  Use the Main menu to set the Product to source or 

simulate current. 

2.  The Product has separate auto ramp and step times. 

Use the menu to set the ramp or step time. 

3. Push 



 once to continually step the output from 

0 % of span to 100 % of span and back in increments 
of 25 % of span at the specified interval.  

4. Push 



 once more to go to auto ramp.  

5.  Push one of the percent keys, and  twice, to turn 

off the auto step and ramp. 

6. Push 



 twice to continually ramp the output from 

0 % of span to 100 % of span over the specified 
interval, and then back over the specified interval.  

7.  Push one of the percent keys or  once more, to 

turn off the auto step and ramp.
