Instrument Specification
At any time during front panel operation, you can confirm the specification of the
voltage measurement. When using the current shunt mode, the specification
shown is the voltage specification and not that of the calculated current
measurement (see Instructions for Current Measurements). The specification is
shown at the top of the display in addition to the Calibration Interval and number
of days since the last verification at all times. An example of the display is shown
below.

Note
For INPUT 1 OR 2, the specification shown is the measurement
mode absolute specification. For WIDEBAND, the specification
shown is the total uncertainty including flatness. For the AUX input,
no specification is shown. The days since verification relates to the
verification procedure for the active input (Periodic or WIDEBAND).

Caution
To avoid dielectric breakdown, use only cables and connectors
that have voltage ratings higher than the voltages you will be
applying.
Connect the source to be measured to the INPUT 1 50 Ω Type "N" connector or
the INPUT 2 binding posts. For the best measurement quality, use a coaxial
cable and INPUT 1 for input frequencies >300 kHz (refer to Table 4-3). For more
information, refer to the Fluke Calibration application note How Cables and
Connectors Impact Measurement Uncertainty. Cable recommendations depend
on the INPUT connector used and the input amplitude and frequency. Table 4-3
gives test lead and INPUT connector recommendations for different applications.
