Select Boost Amplifiers; Error Reference - Fluke Calibration 5730A Operator's Manual

Select Boost Amplifiers

If an auxiliary amplifier other than the 5725A will be used, one amplifier can be
identified for current boost and one amplifier can be identified for voltage boost. Model
5725A is the factory default for both voltage and current boost. To select other
amplifiers:
1. Touch Setup Menu>Instrument Setup>Boost Amp Types.
(If the Setup Menu is not shown, push  first).
The display changes to:
Setup Menu
Boost Amp Types
Voltage
Current
2. Touch Current to scroll the highlighted label until it shows 5725 or 52120.
3. To go to normal operation, touch Exit.

Error Reference

When the output value is edited, the display shows the difference between the reference
value (the value originally entered) and the edit value (the value shown on the display),
displaying error difference in parts per million (ppm) or percent (%).
For example, an edited difference of 0.00030 volts for an output of 10.00000 V
represents 0.00030/10.00000=0.000030, or 30 parts per million. The sign is negative
(-30.0 ppm) because the output necessary to display 10.00000 at the UUT shows the
UUT is reading below the output value. When the reference is negative, the error sign
is relative to the magnitude. For example, if the reference is -10.00000 V and the
display is -10.00030, the error is -30 ppm or -0.0030 %.
The 5730A Calibrator has two methods of scaling the UUT error. The first method, called
the "nominal" method is used in the Fluke Calibration 5700A, 5720A, 5502A, and 5522A
calibrators.
