Heathkit IB-5281 RLC Bridge Resistance Capacitance Inductance Meter
This is a Heathkit IB-5281 RLC Bridge which will measure resistance from 10 ohms to 10 megohms. Capacitance from 10 pF to 10 uF, and inductance from 10 uH to 10 Henries. It can also be used to measure how well matched two components are. The bridge is in very good physical and working condition. I measured some precision components and found resistance measurements to be within about 5% and inductance and capacitance within about 10% The bridge uses two 9V batteries(included) I don't have a printed manual. But I will include a copy of the manual on CD. Shipping weight is about 5 pounds and will ship via USPS Parcel Select or Priority Mail to the lower 48 United States. I accept payment by PayPal.

Power cord, 3 pair of custom component adapter fixtures(made by me) and 1 original GR axial adapter(other one I lost) Five years ago I purchased all of Franklin Computer's engineering laboratory test equipment when they moved their development lab from NJ to China. The equipment was then used in my personal development lab. This unit was lightly used by me and Franklin in a lab environment and hence the reason it is in such wonderful condition; no production abuse what-so-ever. The 1657 is designed around 80s vintage discrete commercial off-the-shelf digital and linear ICs that are still readily available today. So if it ever needs service, its easy to trouble ... moreshoot and repair. 100% guaranteed as to performance and physical condition. If not 100% satisfied. Return for a complete refund.

Heathkit IB-5281 RLC (LCR) Bridge - Accurate - HAM
Heathkit IB-5281 RLC(LCR) Bridge- Accurate- HAM Here's a very nice. Working Heath model IB-5281 RLC bridge for your bench or"shack. It's a portable, battery operated instrument capable of accurately measuring resistance, capacitance, and inductance- either directly or as a comparison bridge for matching components or extending the existing ranges. The IB-5281 specifications are: Resistance 10 Ω to 10 MΩ in three ranges Capacitance 10 pF to 10 µF in three ranges Inductance 10 µH to 10 H in three ranges External Standard Range 1:1 to 10:1 Oscillator Frequencies 1 KHz. 10 KHz& 100 KHz Portable operation using two 9 Volt batteries While ohmmeters are common but generally have few and crowded scales. And capacitance meters are plentiful but at a price; meters that will accurately measure inductance are very few and are ... moregenerally expensive. The Heath IB-5281 is an exception. I bought this meter out of curiosity. Wondering just how accurate an inexpensive bridge like this could be for measuring inductance. I was very pleasantly surprised! It compared favorably with my lab grade HP 4262A digital bridge. I first calibrated the IB-5281 with the included resistor per the instruction manual. Then I connected a(nominal) 10 mH inductor for measurement. The second photo shows the bridge nulled, with a reading of just under 10.1 mH on the X 0.1 mH range. The third photo is of the same inductor being measured on my HP 4262A digital meter as 10.15 mH- very close indeed! The HP 4262A is not included in the auction, of course. This instrument is more than accurate enough for its intended use as a bench instrument. It is also quick and easy to use. Just connect your component to the included clips or test leads. Select your function and range, and adjust the dial for a null on the meter- then read. Please note before bidding that the protruding lip on the front of the case was removed by the original owner to allow easier access to the connectors. The instrument ships with new batteries. Both the clips and
