Re: Tektronix 465 No Trace, No Dot

In the 465 calibration procedure a Simpson 262 (or a Triplett 630-NA) is used as DC voltmeter to check the HV voltage. Both the Simpson 262 and 260 have 20 kOhm/V all range. The 262 has a 4 kV range, so even higher load than the 260 with 5 kV range. Hence the 260 should be OK.
