Question about a power supply tester

[AMDfreak]

I recently got a PSU tester with an LCD readout. One of the readings is labeled "P.G." but I can't figure out what it is, and the manual is no help.

Anyone know what P.G is?

PG = Power Good

This is a 0/1 signal that the power supply sends after it's turned on and it believes that the voltages are stable.

----------------------------------------------
Quote from UseNet:

The power good signal is *from* the PSU *to* the motherboard, Quoted from
the original IBM PC/XT hardware reference manual :-

Power on/off cycle: when the supply is turned off for a minimum of 1.0
second, and then turned back on, the power-good signal will be regenerated.

The power-good signal indicates there is adequate power to continue signal
processing. If the power goes below the specified levels, the power-good
signal triggers a system shutdown.

This signal is the logical AND of the dc output-voltage sense signal and
the ac input voltage fail signal. This signal is TTL-compatible up-level
for normal operation or down-level for fault conditions. The ac fail signal
casues power-good to go to a down-level when any output voltage falls below
the regulation limits.

The dc output-voltage sense signal holds ther power-good signal at a down
level (during power-on) until all output voltages have reached their
respective minimum sense levels. The power-good signal has a turn-on delay
of at least 100 ms but no greater than 500ms.

Hey thanks! :beer:

Just a recommendation, those things are still not as accurate as a digital multimeter. May I suggest using one?
