One thing to verify at time of test is what the System Voltage at the Main Service is, then compare it to the test results.
Could very well be working off a small Transformer, which is at that certain time being loaded by multiple users (customers).
That would bring the "Available VAC" (Ok to say this? kind of improper, but gets point across) at the service down drammatically.
Not sure, but do the "Sure-Test" multitesters use a base reference of 120 VAC for volts lossed calculations, or do they adjust on the fly?
If based on E=120 VAC, then a loaded transformer might result in "other than desireable results", yet the actual scenario might not be so extreme.
Just thinking about some possible things.

BTW, has anyone verified the results of a Sure-Test's volts loss reading with "auxiliary" test methods? (using a Variable Inductive load or Variable Resistance load, or combination of L+R load, then measure Voltage at test end and compare to Voltage at service). Would be curious to know results.
S.E.T.
