Capacitance and ESR Meter (VEL28E)

Features

• ESR measurement range 0 to 40 Ohm
• ESR resolution as low as 0.01 Ohm
• capacitance range 1µF…22mF (22,000µF)
• can also be used for low-Ohms resistance checking
• built-in protection circuitry means risk of damage to the
  unit due to residual charge is greatly reduced
• integrated controlled discharge circuitry reduces the need
  for the user to manually discharge capacitors before test
• use in or out of circuit for ESR measurement
• automatic and manual power-off
• with audible alerts
