3.16.1 Crest Factor in Rectified Mode Explanation
The load current in rectified mode are shown in Figure 3-15, Figure 3-16 and Figure 3-17; it’s
a rectified sine wave, therefore the CF value needs to be set.
3.17 DC Load Simulation -- Timing Mode
Timing Mode can be executed CC, CR, CP, CV and Rectified mode under the DC mode.
The timer starts after Load ON. There are three different conditions for the times to stop. 1.
Load OFF. 2. The UUT voltage drops below the cutoff voltage setting. 3. The timer has
reached the time set.
To switch to Timing mode, the methods are as follows.
1. Press CONF./LOCAL key.
2. Press 1 , then press ENTER to enter SETUP.
