Figure 6-39. DC Source Test Circuit for a SCR
Do the following to dynamically test a SCR using the Tracker 2700:
1. Select the 10V, 1 kΩ
ΩΩ
Ω range.
2. Set the frequency to 60 Hz.
3. Connect the blue easy grabber from Tracker 2700's DC Source +DC output terminal to the
component's gate lead.
4. Connect the red test probe from Tracker 2700's A test terminal to the SCR's anode lead.
5. Connect the black test probe from Tracker 2700's Common test terminal to the SCR's
cathode lead.
