Auto Ramp the Output
When ramped, the source sweeps up or down in value. Use
the Auto Ramp feature to verify a switch or alarm, or when a
smooth increase or decrease of the output function is
necessary. Set the Product to ramp up Pressure or Current.
1. From the main screen, push D (Auto Ramp).
2. Set the Product for the necessary source function:
• B (Pressure)
• C (Current)
3. Use the arrows, numeric keypad, and E to change
the Start Values, End Values, and Slew Rate (Ramp
Time).
4. Select the Repeat Mode:
• B (One Time)
• C (Repetitive)
5. Select the Step Style:
• B (Sawtooth)
• C (Triangle)
6. Push D (Start).
While the signal ramps, the output adjusts to the value. The
selection of endpoints and ramp time determines the size of
steps. For example, if you set the Product to ramp from
1 mV to 1 V over 10 seconds, the output adjusts in
approximately 25 mV steps. The Ramp function continues
until you get the selected limit.
