  • Page 13: Introduction

    INTRODUCTION B&K Precision’s 830C and 890C 11,000-count hand- held capacitance meters measure capacitance and include a capacitance sorting function. Simple to operate, instruments make quick measurements and simplify the capacitance sorting process. Capacitance is measured by using a small DC voltage signal that slightly charges the connected capacitor for a short time.
  • Page 14 A single 9V battery or the included DC 12V power adaptor (included with model 830C only) can be used to power the meter. This gives user flexibility for portable or bench-top use.
