Testing Continuity
• Measurement Method: 0.83 mA ± 0.2% constant current source, < 5 V open
circuit voltage.
• Response Time: 70 samples/ second with audible tone
• Continuity Threshold: 10 Ω fixed
• Input Protection: 1000 V (HI terminal)
Checking Diodes
• Measurement Method: Uses 0.83 mA ± 0.2% constant current source, < 5 V
open circuit voltage.
• Response Time: 70 samples/ second with audible tone
• Input Protection: 1000 V (HI terminal)
