Example of a Periodic Ramp Sequence
Manually Controlled Ramp Sequence
After entering all parameters, start by pressing .
Rising or decaying ramps can be triggered with the  or  key.
The relationship between the output signal and each of the key
operations is depicted with the help of the following example.
Example of a Periodic Ramp Sequence Controlled by Manual Intervention
Ramp parameters: output quantity: U (range of 0  15 V),
start =2V, end =10V, t1 =5s, t2 =8s, t3 =5s, repeat for peri-
odic ramps
Key
1 When ramp ready is displayed:
Start the sequence by pressing .
2 Stop the decaying ramp within decay time t3 with the  or 
key.
3 Start a rising ramp within remaining decay time t3 with the 
key.
4 Stop the ramp sequence by pressing the  or  key.
5 Start a decaying ramp with the  key, remaining dwell time t2
is cleared.
6 Stop the ramp sequence by pressing .
