Measuring Continuity; Measuring Diode; Battery Test - Amprobe AM-420 User Manual

Measuring Continuity

X�
Disconnect circuit power and
discharge all high-voltage
capacitors before testing continuity.
Meter beeps at ≤10Ω, beeper turns
off at > 70 Ω

Measuring Diode

X�
Disconnect circuit power and
discharge all high-voltage
capacitors before testing diode.

Battery Test

X�
Applying a voltage source or
incorrect battery type under battery
test may cause personal injury or
damage to the Meter.
