1. Brief introduction

TH2685/TH2686 Electrolytic Capacitor Leakage Current Meter is a kind of instrument on
the basis of Micro Process Technique, which can test the parameter of electrolytic capacitor
leakage current automatically.

The instrument can meet the demand of IEC about each electrolytic capacitor leakage

current. The test range of leakage current is 10nA~20mA，totally 5 bins, and adopting 3 1/2
digit display. The instrument can select the range automatically according to the set leakage
current value, and the test voltage can be adjusted continuously adopting 3 digit display. Charge
–test can be transformed automatically, and the charge time can be set within 0~99.9 s. The
instrument also have the feature of sorting over-limit indication, high accuracy, fast speed,
convenient operation, and reliability, which can is suitable for the production line of electrolytic
capacitor factory, incoming inspection of components as well as the measurement and sorting
on the electrolytic capacitor leakage current in colleges and the department of scientific research,
measurement units and quality control.

The instrument is consonant with the demand of 2
