1 Press the key to enter into the mode selection and parameter setting menu; use
▲
and
▼
keys to select one basic operating
mode; press the Enter key to confirm and exit the mode selection and parameter setting menu.
2 Press the key to enter into transient operation. The display shows “t” to indicate in the basic test mode.
3 Press the key to enter into the transient operation menu.
4 Use
▲
and
▼
keys to select the parameter: LevelL, LevelH, TimeL, TimeH, TimeR und TimeF
5 Use Entry keys or use the knob together with ◄ ► keys to set values for LevelL, LevelH, TimeL, TimeH, TimeR, and TimeF.
Use ◄ ► keys or knob to set Mode value: continuous, pulsed or toggled operation.
6 Press the key to exit the transient operation menu.
7 Press the key to turn on the load.
8 If it is the pulsed transient operation or the toggled transient operation, one trigger occurs when pressing key + key or
the signal at the trigger input terminal (TRIG IN) is low level.
4.7.1 Continuous Transient Operation
In continuous transient operation, the load switches at defined intervals between high and low level.
Relevant parameters:
– low-Pegel (LevelL),
– high-Pegel (LevelH),
– low-Pegel-Zeit (TimeL),
– high-Pegel-Zeit (TimeH),
– time for rising edge (TimeR) and
– time for falling edge (TimeF).
Example 1: Set the load voltage value to periodically switch between 1 V and 5 V; set the time for rising edge (TimeR) to 10 ms; set
high level time (TimeH) to 200 ms; set time for falling edge (TimeF) to 20 ms; set low level time (TimeL) to 400 ms, and the load is in
continuous transient operation. The operating procedures are shown as below:
