Data Sheet
In-Circuit ESR & DC Resistance Capacitor Tester
Model 881
Model 881 is a new portable In-Circuit ESR Meter, the new compact hand-held tester can
be used to measure the equivalent series resistance of electrolytic capacitors in or out of
circuit and can also be used to measure low value non-inductive resistors. Model 881 is a
must for anyone that tests or trouble shoots printed circuit boards.
