Since ICE is no longer producing these in their original capacity, the community has stepped in. You can typically find the on the following types of sites:
Locating an original manual in good condition can be challenging for a vintage instrument. However, a key part of maintaining and effectively using the Supertester 680 R is having access to the correct manual. This is particularly important as the 680 R was produced over several decades, resulting in different series (IV, V, VI, VII, etc.), each with slight variations in features, component layouts, and calibration procedures.
Short the tips of the red and black probes together. The needle will swing toward zero on the top right of the scale.

The ICE Supertester 680 R is a high-sensitivity instrument, offering . While a sensitivity of 20,000 Ω/Volt was standard for professional test equipment at the time, what set the 680 R apart was its exceptional precision of 0.5% on DC ranges , thanks to its use of modern metallic layer resistors. These components not only provided a precision of 0.5% but also guaranteed this level of precision with stability in absolute time that was four times greater than the "precision" resistors used in other test meter analyzers available at the time.
Leo laughed, but the lab was empty. The hum of the 680 R seemed to deepen.
The resistance measurements are protected by an internal fuse, reducing the risk of damage during misuse. Since ICE is no longer producing these in
The Supertester 680 R was manufactured by (International Controlled Electronics) before the company was absorbed by Amprobe (now a subsidiary of Fluke). Because the model has been discontinued for over 15 years, official PDFs are no longer hosted on primary manufacturer support sites.
Some of the resources listed above, particularly the "Operator's Manual and Repair Manual" on manualslib.com, contain sections on maintenance and repair. Additionally, online electronics communities (like the Italian forum ElectroYou) often have discussions and tips from owners who have repaired their units, and an Italian user on a forum was working on restoring a 5th series, suggesting the information is available.
