Information
The
792A AC/DC Transfer Standard is a laboratory standard
instrument that calibrates ac voltage calibrators, ac/dc
transfer standards, and ac voltmeters. It consists of four
main components: a transfer standard sensor unit (called the
transfer standard in this manual), power pack, 1000V range
resistor, and transfer switch.
Inputs are accepted in the range 2 mV to 1000V rms, 10 Hz up
to 1 MHz, with a maximum Volt-Hertz product of 10 The 792A
compares the heating effect of an ac voltage with that of a
known dc voltage (or other ac voltage). Sensing the rms
value is done entirely without thermocouples and the
drawbacks that accompany them. (See The
Fluke RMS Sensor,
paragraph 1-3, for more information.)
The transfer standard accepts dc and ac voltages through a
stainless steel Type “N” INPUT connector and presents a dc
voltage at the front panel DC OUTPUT binding posts that is
linearly proportional to the rms potential of the input. A
digital voltmeter of 6V4-digit resolution or better can be
used to resolve the 2.0V nominal full-scale output.
An OVERLOAD indicator and beeper warns of input overloads.
Even though the transfer standard is protected
electronically from overloads, it is a delicate laboratory
instrument and should be treated with extreme care.
Before operating the transfer standard, be sure to read
Sections 2 and 3, particularly the WARNING that explains the
restriction to use only sources that are current-limited to
200 mA or less (at the beginning of Section 2), and the
CAUTION about observing the voltage protection level limits
for each INPUT RANGE setting.
