[GreenKeys] ST6 testing...

I am just wondering if the ST-6 is supposed to have a loop load with
a Teletype attached when you are making those measurements?
Bill Henry could probably tell you right off the top of his head.

hello all, did a little investigating on one of the nicer ST6's I got
in the batch of 3 on ebay ($60!). I decided before I plugged it all
in and fried everything, I would perform some basic measurements
according to the manual...
On page 22 of the manual, it gives several voltages to check on the
various edge connectors. My AC voltages all seem higher. Could this
be simply due to higher house voltage from when the ST6 was designed
and sold (The ST6 in question seems to be a factory one). For example:
(2)(a) - pins M&N should be 26VAC, mine is 37VAC
(2)(b) - should be 13 vac, mine is 18vac
(2)(c) - should be 250 vac, mine is 297 vac.
Or, perhaps, could this be RMS vs peak or something? I am using a
fluke 8840A/AF meter (very nice, but the darn keys stop working after
a while). I am pretty sure my meter is reading RMS. Just as a point
of reference, when I connect this meter to the AC line directly, I
get a reading of 120 vac
Should I worry about any of this?
Thanks
