Setup and Other Functions

SCAL SCALING
- ING
This menus enables the user to scale the readings of the PM3300 to
OFF suit the ratio of external voltage and current transducers. If required
ON inputs may be individually scaled to match calibrated transducers.

This key will provide useful information regarding the detailed setup
features available with the MENU+PROG keys (see below), and
waveform and harmonic display configuration.

LOCAL LOCAL

This allows the user to switch from remote control (IEEE or RS232) to

Apk PM3300 is fully autoranging for both voltage and current over the
RANGE whole input range. Independent channel ranging is selectable.

Manual ranging can be selected for recording transient events such
as motor start-up currents, or for use with data-log.

In each case the selected range is indicated on the 12 element
bargraph on the front panel. An overload on any range will be
indicated by the PM3300 display.
