Velleman Measuring device ESR

Velleman ESR70 measuring device for ESR, low resistance and capacitance,
Properties

ESR measuring range : from 0 to 20 Ohm
low ESR resolution: 0.01 Ohm
Capacitance range: 1µF...22mF (22.000µF)
is also suitable for measuring low resistances
the built-in discharge circuit ensures that a charged capacitor does not damage the device
with the integrated controlled discharge circuit the user has to discharge the capacitors manually before the test
for use inside or outside the circuit for ESR and low ohmic resistance measurements
automatic and manual switch-off
with audible alerts
