Signstek 2 in 1 Digital Auto-ranging ESR + Capacitance Meter 0-470Ω ERS 0μF-470mF Rechargeable Capacitance Tester and Internal Resistance Tester with SMD Test Clips and USB Cable

Description

Features
Measure method: We have 4 range of charging current from 100uA to 50mA, we can ge the capacitance value by counting the time for charge a capacitor to 0.55V
Auto sleep: Around 15minute for not testing, it will shut down automatically to save power; Over flow or OL: Display overflow when the value is out of range, you need to check that if you are zero correctly
ERS form: it is for reference only; different manufacturer of capacitor has different ERS, better to test a good cap ERA and compare with what you are testing, usually bad cap with higher ERS cost few time lager


Notice
Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter
It doesn t support IN CIRCUIT Testing
This meter can measure low resistance, but can t be used for wire wound resistor
