Thank you, Nute.
Page 70 of the manual indicates the ability to select a measuring network.
According to the first paragraph on this page, it's a meter only for voltage
measurements. Page 71 shows how to select a measurement network when using
meter mode.
FWIW, I used Networks A, B and G on
Thank you, John.
Agreed, but I have also moved the conductors around, used multiple wire
routings, multiple power sources, power systems in two buildings, on a ground
plane (this was happenstance in the second building)...
While the results have minor differences, the effects I'm seeing are
Doug,
None of the machinery standards require lighting in the panel, they simply
permit it where the designer wants to use it, and provide rules for the
installation should you choose to install it. A risk assessment should be the
deciding factor, and any customer preferences for the provision
Agree with Mr. Woodgate, but there are additional problems. A good reference
for this is Mr. Perkin's presentations and articles on the subject. Current and
voltage waveforms in ground and touch Type Tests for switch-mode power supplies
are very complex; and can vary in amplitude, frequency,
Hello Peter:
I downloaded the TOS3200 manual to better
understand your problem.
When the TOS3200 is in "meter mode," the terminals
A-B comprise an ammeter (without the body
impedance network). This will yield a higher
current than in the TC (touch current) mode. I'm
not sure if A-B can have
Stray capacitances are different in the two modes, but probably only affect
measurements if there are relatively strong high-frequency components in the
current.
