Default Re: AVO Multimeter survey

Superhet,

As you will have seen from the link you quote, this is a "Test Set No. 1", essentially a screened, panclimatic variant of the Model 8 with 1-3-10 series ranges, rather than the 1-2.5-10 of the corresponding civil models. The military versions also have the resistance scales on the INSIDE arc of the scale plate which makes sense since the voltage and current ranges are the more accurate ones and hence benefit most from the greater scale length. The alternating current ranges are 10A, 2.5A, 1A and 100mA on the civil models; on the Test Set Mk I, the second value is 5A instead of 2.5A

By 1967, the Model 8 had reached the Mk III version. The Model 8 Mark I was never officially known as anything other than simply the Model 8.

With a DC accuracy of 1% and its very robust construction, many people who don't mind the weight would argue that this is possibly the best Avometer ever made.
