Setting Ramp Parameters
seleCt range 300 mV … 15 V V Z ramp
Initial value:
ramp start 02.000 V YZ UV
Final value: ramp end 10.000 V YZ UV
Rise time:
ramp t1 00.05 min.s YZ UV
Dwell time:
ramp t2 00.08 min.s YZ UV
Decay time:
ramp t3 00.05 min.s YZ UV
Repetition: ramp mode repeat V onCe
(rEPEAT = endless loop, onCE = one-time only)
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 U or V 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 U or V
key.
3 Start a rising ramp within remaining decay time t3 with the U
key.
4 Stop the ramp sequence by pressing the U or V key.
5 Start a decaying ramp with the V key, remaining dwell time t2
is cleared.
6 Stop the ramp sequence by pressing .
