Here are specs from an older General Radio Bridge for observation.
GR 1644-A specifications:
Resistance Range: 1 kΩ to 1000 TΩ (10^3 to 10^15 Ω) in ten ranges.
Accuracy: 10^3 Ω to 10^10 Ω, ±1 %. After self-calibration: 10^10 to
10^12 Ω, ±1%*; 10^13 Ω, ±2%; 10^14 Ω, ±10%; 10^15 Ω, ± one scale

Yes, David, unless you go to very extreme measures, you won't see real R
values that have any practical meaning beyond E12 ohms or so. Most
practical insulation Rs may be around E12-E14 tops, unless you go to

Maybe one bad resistor? I've read that tin whiskering can occur even on
relatively recent equipment, slower than lead free but still a problem.
I'd do a visual inspection just to see, shouldn't be an issue.
