Chapter 5 Data Display
Table 5-1 lists all displayed parameters and their LED indicators.
Load Bar Graph
The load bar graph displays the amount, in percent, of the current load
with respect to user-defined nominal load current. The highest current
measured by the PM172EH is divided by the nominal load current as
defined in the Display Setup Menu (see Section 4.11) and expressed as a
percent by the LEDs (40% to 110%) which are lit. For example, if all LEDs
up to and including 90% are lit, this means that the load is 90% of the
nominal load current. If the nominal load current is set to 0, it is taken
from the CT primary current setup.
Auto Scroll
If display Auto Scroll option is enabled (see Section 4.11), the common
measurements display (main screen)
will scroll automatically after 30
seconds of uninterrupted use.

Auto Return to the Main Screen
If display Auto Return option is enabled (see Section 4.11), the display
will automatically return to the main screen from any other measurement
screen after 30 seconds of uninterrupted use.
Fast Reset of Accumulated Data
When changing data via the front panel is not secured by a password,
you can reset the Min/Max registers, maximum demands and total
energies from the display mode without entering the reset menu.
NOTES
1.
The common measurements display (main screen) does not have a
designated indicator LED. If no arrow LED is lit up below the display, this
means that the common measurement parameters are being displayed at
this time. To return to the common measurements from another group, just
press the same key that you used to display this group (the key pointed to
by an illuminated arrow LED) until the illuminated LED goes out.
2.
When you move to another measurement group, the instrument stores
your last location; when you return to the previous group, the instrument
restores the last page. At power up, the instrument always returns to the
common measurements group and shows you the last page that was
displayed prior to loss of power.
