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 C191HM is divided by the nominal load current as defined in the Display
Setup Menu (see Section 4.8) 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.
Alarm LED
The blinking Alarm LED gives you an alarm indication. It is controlled by the
alarm/event setpoints (see Section 4.6) and operates in latched mode. Even if
alarm conditions are no longer present, the alarm LED will continue to blink. To
clear the alarm LED, press the up/down arrow keys simultaneously for 5
seconds.

reset the Min/Max registers, maximum demands and energies from the display
mode without entering the reset menu.
NOTES
1. The common measurements display does not have a designated indicator LED. If no
indicator 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, press the illuminated key until it 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.
