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. Measures ESR with a range of 0.1 to 30 ohms. Three color front panel chart shows ESR reading s of good, fair, and bad. Measures DC Resistance with a range of 0.1 to 30 ohms. Automatically calibrates internal signal. 15mVp-p Output test voltage (will not turn on any solid state devices). Includes a one-handed tweezers test probe. Uses a standard 9VDC battery as power Source, 100 MHz Bandwidth. Open circuit probe voltage: 15mV pp. Output test frequency: 100 KHz sine wave. Measures ESR range ohm: 0.1 - 30 (25 segment LED bar scale) beeps from 1 to 5 beeps depending on ESR of capacitor. Measures DC Resistance range ohm: 0.5 - 30 flashing the LED. Power: one 9V battery or an external AC adapter (9V DC 100mA 5.5mm x 2.1mm center pin+). Power drain: 10mA typical. Measures 1-1/2" length by 3-51/64" width by 5-11/16" height. 1 year warranty.
